VAHANNA TECH EDGE ACQUISITION I CORP.

Dear Shareholder:

You are cordially invited to attend the special meeting (the “Vahanna Special Meeting”) of Vahanna Tech Edge Acquisition I Corp., a British Virgin Islands business company (“Vahanna”), at 10:00 a.m., New York time, on August 25, 2023, at the offices of Winston & Strawn LLP at 200 Park Avenue, New York, New York 10166 and virtually at https://www.cstproxy.com/vahannatech/sm2023.

On February 10, 2023, Vahanna entered into an Agreement and Plan of Merger (as amended, the “merger agreement”) with Vahanna Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of Vahanna (“Merger Sub”), and Roadzen, Inc., a Delaware corporation (“Roadzen”), whereby Merger Sub will merge with and into Roadzen, with Roadzen surviving the merger as a wholly owned subsidiary of Vahanna (the “merger”).

In the event that redemptions of Vahanna Class A Ordinary Shares, par value $0.0001 per share (the “Class A Ordinary Shares”), in connection with the Vahanna Special Meeting are less than approximately 48% of the issued and outstanding shares of capital stock of Vahanna, which is comprised of 20,010,000 Class A Ordinary Shares and 5,002,500 Vahanna Class B Ordinary Shares, par value $0.0001 per share (the “Class B Ordinary Shares,” and together with Class A Ordinary Shares, the “Vahanna ordinary shares”), then at least one (1) business day prior to the merger, Vahanna will change its domicile by way of its continuation out of the British Virgin Islands, as a business company incorporated under the laws of the British Virgin Islands, and into the State of Delaware to become a corporation incorporated under the laws of the State of Delaware (the “Domestication”). In connection with the merger or, as applicable, the Domestication, Vahanna will change its name to Roadzen Inc. (“New Roadzen”).

In connection with the merger, New Roadzen will issue or reserve for issuance 68,300,000 ordinary shares, par value $0.0001 per share, of New Roadzen (the “New Roadzen Ordinary Shares”, and if the Domestication occurs pursuant to the terms of the merger agreement, following the effective time of the merger, references herein to “New Roadzen Ordinary Shares” shall mean common stock, par value $0.0001 per share, of New Roadzen) (such consideration, the “Merger Consideration”). Each outstanding share of Roadzen common stock, including common stock held by prior owners of Roadzen preferred stock (other than shares owned by Roadzen as treasury stock and dissenting shares) (“Existing Roadzen Common Stock”) will represent a right to receive a pro rata portion (on a fully-diluted basis) of Merger Consideration. New Roadzen will also reserve a portion of the Merger Consideration for issuance upon the future conversion, exercise, vesting and/or settlement of any other equity security of Roadzen (other than Existing Roadzen Common Stock, warrants of Roadzen and Roadzen RSUs) issued and outstanding immediately prior to the effective time of the merger (the “New Roadzen Assumed Additional Securities”). In addition, a portion of the Merger Consideration shall be used for Roadzen RSUs (as defined below) outstanding immediately prior to the merger and converted into New Roadzen RSUs (as defined below) that are assumed under the Incentive Plan (as defined below).

If no public shareholders exercise their redemption rights with respect to the public shares they hold, New Roadzen’s ordinary shares issued and outstanding immediately after the business combination is expected to be as follows: (a) former Roadzen stockholders, 70.0%; (b) public shareholders of Class A Ordinary Shares, 24.0%; and (c) holders of Class B Ordinary Shares, 6.0%. If the public shareholders fully exercise their redemption rights with respect to all of the public shares they hold, the combined company’s ordinary shares issued and outstanding after the business combination are expected to be as follows: (a) former Roadzen stockholders, 92.1%; (b) public shareholders of Class A Ordinary Shares, 0.0%; and (c) Vahanna holders of Class B Ordinary Shares, 7.9%.

Subject to the assumptions set forth under “Basis of Presentation and Glossary” in the accompanying proxy statement/prospectus, the exchange ratio would have been approximately 27.459 New Roadzen Ordinary Shares for each share of Existing Roadzen Common Stock (assuming for purposes of such calculation that all shares of Roadzen preferred stock and all options and warrants to purchase capital stock of Roadzen, in each case

outstanding immediately prior to the Effective Time (as defined below), have converted into New Roadzen Ordinary Shares) with any resulting fractional New Roadzen Ordinary Shares rounded up to the nearest whole share.

Vahanna’s units, Class A Ordinary Shares and public warrants are publicly traded on the Nasdaq Stock Market (“Nasdaq”). In connection with transactions contemplated by the merger agreement, Vahanna units will automatically be separated into their underlying Class A Ordinary Shares and public warrants, with any fractional public warrants being forfeited for no consideration. We have applied to list the New Roadzen Ordinary Shares and public warrants on Nasdaq under the symbols RDZN and RDZNW, respectively, upon the closing of the merger.

The Vahanna Special Meeting is being held in lieu of the 2023 annual meeting of shareholders to consider matters relating to the proposed merger. Vahanna and Roadzen cannot complete the merger unless Vahanna’s shareholders consent to the approval of the merger agreement and the transactions contemplated thereby, including the issuance of New Roadzen Ordinary Shares to be issued as the merger consideration, and Roadzen’s stockholders’ consent to adoption and approval of the merger agreement and the transactions contemplated thereby. Vahanna is sending you this proxy statement/prospectus to ask you to vote in favor of these and the other matters described in this proxy statement/prospectus.

The Vahanna Special Meeting will be held on August 25, 2023 at 10:00 a.m., New York time, at the offices of Winston & Strawn LLP at 200 Park Avenue, New York, New York 10166. You can participate in the meeting, vote, and submit questions via live webcast by visiting https://www.cstproxy.com/vahannatech/sm2023 and entering the voter control number included on your proxy card. You will not be required to attend the meeting in person in order to vote, and Vahanna encourages virtual participation. You will need the control number that is printed on your proxy card to enter the Vahanna Special Meeting.

VAHANNA TECH EDGE ACQUISITION I CORP.

NOTICE OF THE SPECIAL MEETING IN LIEU OF 2023 ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON AUGUST 25, 2023

NOTICE IS HEREBY GIVEN that a special meeting in lieu of the 2023 annual meeting of the shareholders (the “Vahanna Special Meeting”), of Vahanna Tech Edge Acquisition I Corp., a British Virgin Islands business company (which is referred to as “Vahanna”) will be held at 10:00 a.m., New York time, on August 25, 2023, at the offices of Winston & Strawn LLP at 200 Park Avenue, New York, New York 10166. You can participate in the meeting, vote, and submit questions via live webcast by visiting https://www.cstproxy.com/vahannatech/sm2023 and entering the voter control number included on your proxy card. You will not be required to attend the meeting in person in order to vote, and Vahanna encourages virtual participation. Vahanna recommends that you log in at least 15 minutes before the Vahanna Special Meeting to ensure you are logged in when the meeting starts. You are cordially invited to attend the Vahanna Special Meeting for the following purposes:

These proposals, along with Proposal No. 2, will only be presented and voted upon in the event that holders elect to redeem 12,000,000 or more Class A Ordinary Shares, par value $0.0001 per share, in connection with the Vahanna Special Meeting (or at least approximately 48% of the issued and outstanding Vahanna ordinary shares, which is comprised of 20,010,000 Class A Ordinary Shares and 5,002,500 Class B ordinary shares, par value $0.0001 per share (the “Class B Ordinary Shares”, and together with the Class A Ordinary Shares, the “Vahanna ordinary shares”)). If not, we will present Proposals No. 4 through 6D.

These proposals, along with Proposal No. 5, will only be presented and voted upon in the event that elections to redeem Class A Ordinary Shares in connection with the Vahanna Special Meeting are less than 12,000,000 Class A Ordinary Shares (or less than approximately 48% of the issued and outstanding Vahanna ordinary shares).

Only holders of record of Class A Ordinary Shares and Class B Ordinary Shares at the close of business on July 21, 2023 (the “Record Date”) are entitled to notice of the Vahanna Special Meeting and to vote at the Vahanna Special Meeting (or any adjournments or postponements of the Vahanna Special Meeting). The eligible Vahanna shareholder list will also be available at that time on the Vahanna Special Meeting website for examination by any shareholder attending the Vahanna Special Meeting live audio webcast.

Pursuant to Vahanna’s Existing Charter, Vahanna will provide holders (“public shareholders”) of its Class A Ordinary Shares with the opportunity to redeem their Class A Ordinary Shares for cash equal to their pro rata share of the aggregate amount on deposit in the trust account (the “Trust Account”), which holds the proceeds of Vahanna’s initial public offering (“IPO”) as of two (2) business days prior to the consummation of the transactions contemplated by the Business Combination Proposal (including interest earned on the funds held in the Trust Account (net of taxes paid or payable, if any)) upon the closing of the transactions contemplated by the merger agreement. For illustrative purposes, based on funds in the Trust Account of approximately $209.3 million on March 31, 2023, the estimated per share redemption price would have been approximately $10.46, inclusive of additional interest earned on the funds held in the Trust Account and not previously released to Vahanna to pay taxes. Public shareholders may elect to redeem their shares even if they vote for the Business Combination Proposal. A public shareholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Class A Ordinary Shares, without the prior written consent of Vahanna. Vahanna LLC, a Delaware limited liability company (the “Sponsor”), and Vahanna’s officers and directors have agreed to waive their redemption rights in connection with the consummation of the merger with respect to any Class A Ordinary Shares they may hold. Currently, the Sponsor owns approximately 19.4% of the Vahanna ordinary shares, consisting of Class B Ordinary Shares, initially purchased by the Sponsor in a private placement (together with any Class A Ordinary Shares issued upon the conversion thereof, “Founder Shares”). Vahanna’s directors and officers do not own any Vahanna ordinary shares. Founder Shares will be excluded from the pro rata calculation used to determine the per share redemption price. The Sponsor and Vahanna’s directors and officers have agreed to vote any Founder Shares owned by them in favor of the proposals set forth in this proxy statement/prospectus.

Approval of each of the proposals set forth herein requires the affirmative vote of a majority of the votes cast by holders of Class A Ordinary Shares and Class B Ordinary Shares, voting together as a single class at a meeting at which a quorum is present. The Vahanna board of directors has already approved each of the proposals.

As of March 31, 2023, there was approximately $209.3 million in the Trust Account, which Vahanna intends to use for the purposes of consummating a business combination within the time period described in this proxy statement/prospectus and to pay approximately $6,525,000 in deferred underwriting commissions to the underwriters of the IPO. Each redemption of Class A Ordinary Shares by its public shareholders will decrease the amount in the Trust Account. Vahanna will not consummate the merger if the redemption of Class A Ordinary Shares would result in Vahanna’s failure to have at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (or any successor rule).

If Vahanna shareholders fail to approve the Business Combination Proposal, the Nasdaq Proposal or, as applicable, the Charter Proposal, the Domestication Proposal or the Delaware Charter Proposal, the merger will not occur. The Charter Proposal, the Domestication Proposal, the Delaware Charter Proposal, the ESPP Proposal and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal and the Nasdaq Proposal. The Adjournment Proposal, the Governance Proposals and the Delaware Governance Proposals are not conditioned on the approval of any other proposal. The proxy statement/prospectus accompanying this notice explains the merger agreement and the transactions contemplated thereby, as well as the proposals to be considered at the Vahanna Special Meeting. Please review this proxy statement/prospectus carefully.

The Vahanna board of directors has set July 21, 2023 as the record date for the Vahanna Special Meeting. Only holders of record of Vahanna ordinary shares at the close of business on July 21, 2023 will be entitled to notice of and to vote at the Vahanna Special Meeting and any adjournments or postponements thereof. Any shareholder entitled to attend and vote at the Vahanna Special Meeting may attend the meeting virtually and is entitled to appoint a proxy to attend and vote on such shareholder’s behalf. Such proxy need not be a holder of Vahanna ordinary shares.

YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF VAHANNA ORDINARY SHARES YOU OWN. Whether or not you plan to attend the Vahanna Special Meeting, please complete, sign, date and mail the enclosed proxy card in the postage-paid envelope provided at your earliest convenience. You may also submit a proxy by telephone or via the Internet by following the instructions printed on your proxy card. If you hold your shares through a broker, bank or other nominee, you should direct the vote of your shares in accordance with the voting instruction form received from your broker, bank or other nominee.

The Vahanna board of directors has unanimously approved the merger agreement and the transactions contemplated thereby and recommends that you vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposal, “FOR” the Governance Proposal, “FOR” the Domestication Proposal (to the extent required), “FOR” the Delaware Charter Proposal, “FOR” the Delaware Governance Proposal (to the extent required), “FOR” the Nasdaq Proposal, “FOR” the Incentive Plan Proposal, “FOR” the ESPP Proposal, and “FOR” the Adjournment Proposal (to the extent required).

QUESTIONS AND ANSWERS

The following are answers to certain questions that you, as a shareholder of Vahanna may have regarding the merger and the Vahanna Special Meeting (as defined below). We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the annexes to this proxy statement/prospectus.

QUESTIONS AND ANSWERS ABOUT THE MERGER

Vahanna will hold a special meeting in lieu of the 2023 annual meeting of Vahanna shareholders (the “Vahanna Special Meeting”) to, among other things, obtain the approvals required for the merger and the other transactions contemplated by the merger agreement and you are receiving this proxy statement/ prospectus in connection with such meeting. Roadzen is also providing consent solicitation materials to the holders of Existing Roadzen Common Stock and the holders of Roadzen’s preferred stock, par value $0.0001 per share, designated as “Series A Preferred Stock” (including the preferred stock designated as “Series A-1 Preferred Stock”) in its Certificate of Incorporation (as amended, the “Roadzen certificate”) (collectively, the “Roadzen Preferred Stock”) to solicit, among other things, the required written consent to adopt and approve in all respects the merger agreement and the merger (the “Business Combination Proposal”). See the section titled “The Merger Agreement.” In addition, a copy of the merger agreement is attached to this proxy statement/prospectus as Annex A. We urge you to carefully read this proxy statement/ prospectus and the merger agreement in their entirety.

The merger cannot be completed unless Vahanna’s shareholders approve the Business Combination Proposal, the Charter Proposal, the Nasdaq Proposal, the Incentive Plan Proposal and the ESPP Proposal, and, if the Domestication occurs, the Domestication Proposal and the Delaware Charter Proposal, set forth in this proxy statement/prospectus. Information about the Vahanna Special Meeting, the merger and other business to be considered by shareholders at the Vahanna Special Meeting is contained in this proxy statement/prospectus.

This document constitutes a proxy statement and a prospectus of Vahanna. It is a proxy statement because the board of directors of Vahanna is soliciting proxies using this proxy statement/prospectus from its shareholders. It is a prospectus because Vahanna, in connection with the merger, is offering New Roadzen Ordinary Shares in exchange for the outstanding shares of Existing Roadzen Common Stock. See “The Merger Agreement — Merger Consideration.”

vii

Assuming the proposals set forth herein are approved and the Domestication occurs pursuant to the merger agreement, Vahanna will continue out of the British Virgin Islands, as a business company incorporated under the laws of the British Virgin Islands, and into the State of Delaware to become a corporation incorporated under the laws of the State of Delaware, and in connection therewith adopt and file the Interim Charter.

Following the Domestication and adoption of the Interim Charter, and upon consummation of the merger and adoption of the Proposed Delaware Charter, securities of Vahanna shall convert on the same basis as if

viii

no Domestication had occurred, except that such securities shall convert to or represent the right to acquire shares of common stock, par value $0.0001 per share (in the event that a Domestication occurs, “New Roadzen Common Stock”).

Vahanna’s units, Class A Ordinary Shares and public warrants are currently publicly traded on Nasdaq under the symbols “VHNAU,” “VHNA,” and “VHNAW,” respectively. Upon consummation of the merger, New Roadzen will have one class of ordinary shares (or common stock in the event of the Domestication) that will be listed on Nasdaq under the symbol RDZN and its public warrants will be listed on Nasdaq under the symbol RDZNW. New Roadzen will not have units traded on Nasdaq following the consummation of the merger and existing units will automatically be separated into their component securities without any action.

Subject to the assumptions set forth under “Basis of Presentation and Glossary” in the accompanying proxy statement/prospectus, the exchange ratio would have been approximately 27.459 New Roadzen Ordinary Shares for each share of Existing Roadzen Common Stock (assuming for purposes of such calculation that all outstanding shares of Roadzen Preferred Stock and Roadzen RSUs have converted into Existing Roadzen Common Stock), except for any resulting fractional New Roadzen Ordinary Shares.

In addition, because Vahanna is expected to qualify as a passive foreign investment company (“PFIC”), proposed U.S. Treasury Regulations under Section 1291(f) of the Code (which have a retroactive effective date), if finalized in their current form, generally would require a U.S. Holder to recognize gains as a result of the Deemed Domestication or the Domestication, as applicable, unless the U.S. Holder makes (or has made) certain elections discussed further under “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — Passive Foreign Investment Company Rules.” The tax on any such gain would be imposed at the rate applicable to ordinary income and an interest charge would apply based on a complex set of rules. It is difficult to predict whether such proposed regulations will be finalized and whether, in what form, and with what effective date, other final U.S. Treasury Regulations under Section 1291(f) of the Code will be adopted.

Vahanna received a written opinion dated as of the date hereof, to the effect that, as of the date hereof and subject to the qualifications, assumptions and limitations set forth herein and in the opinion attached as

ix

Exhibit 8.1 to the Registration Statement of which this proxy statement/prospectus forms a part, the statements of law and legal conclusions set forth below under the headings “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — The Deemed Domestication” and “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — The Domestication” constitute the opinion of Gibson, Dunn & Crutcher LLP as to the material U.S. federal income tax consequences of (i) the Deemed Domestication to the Holders of Vahanna Securities, (ii) an exercise of redemption rights generally applicable to Holders of Class A Ordinary Shares following the Deemed Domestication, (iii) the ownership and disposition of Vahanna Securities following the Deemed Domestication, (iv) the Domestication to the Holders of Vahanna Securities, (v) an exercise of redemption rights generally applicable to Holders of Class A Ordinary Shares following the Domestication, and (vi) the ownership and disposition of Vahanna Securities following the Domestication.

Additionally, the Deemed Domestication or the Domestication, as applicable, may cause Non-U.S. Holders (as defined in “Material U.S. Federal Income Tax Considerations” below) of Existing Roadzen Common Stock or Class A Ordinary Shares, as applicable, to become subject to U.S. federal income withholding taxes on any redemption of such Non-U.S. Holder’s Existing Roadzen Common Stock or Class A Ordinary Shares, as applicable, and on any amounts treated as dividends paid in respect of such Non-U.S. Holder’s Existing Roadzen Common Stock or Class A Ordinary Shares, as applicable, after the Deemed Domestication or the Domestication, as applicable (as discussed more fully under the section “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of Non-U.S. Holders”).

For a discussion of the material U.S. federal income tax considerations applicable to Holders (as defined below) with respect to the merger, see the section titled “Material U.S. Federal Income Tax Considerations.”

However, neither Vahanna nor Roadzen can assure you of when or if the merger will be completed and it is possible that factors outside of the control of both companies could result in the merger being completed at a different time or not at all. Vahanna must first obtain the approval of Vahanna shareholders for each of the proposals set forth in this proxy statement/prospectus for their approval (other than the Adjournment Proposal) and Vahanna and Roadzen must also first obtain certain necessary regulatory approvals and satisfy other closing conditions. See the section titled “The Merger Agreement — Conditions to the Merger.”

Instead, Roadzen will remain an independent company. See the sections titled “The Merger Agreement — Termination” and “Risk Factors.”

The Domestication will require Vahanna to file certain documents in both the British Virgin Islands and the State of Delaware. At the effective time of the Domestication (which will occur, if at all, at least one

x

(1) business day prior to the merger), Vahanna will cease to be a business company under the laws of the British Virgin Islands and in connection with the transactions contemplated by the merger agreement, New Roadzen will continue as a Delaware corporation. In connection with the Domestication, the Existing Charter will be replaced by the Interim Charter and your rights as a shareholder will cease to be governed by the laws of the British Virgin Islands and will be governed by Delaware law.

No sooner than one (1) business day following the Domestication, assuming the satisfaction of the conditions to close the merger agreement, we will effectuate the merger. Concurrently, the Interim Charter will be amended and restated in its entirety and replaced with the Proposed Delaware Charter.

The number of Class A Ordinary Shares redeemed and whether the Domestication Proposal will be called to a vote will be known and determined by Vahanna on the evening of the redemption deadline, the date that is two (2) business days prior to the Vahanna Special Meeting. To inform shareholders regarding whether the Domestication Proposal is required to be called for a vote (i.e., if holders of less than 12,000,000 Class A Ordinary Shares have elected to redeem such shares), Vahanna expects to issue a press release following the redemption deadline, but prior to the deadline for shareholders to vote on proposals to be presented at the Vahanna Special Meeting, announcing whether the Domestication Proposal will be called for a vote or if Vahanna will continue as a business company incorporated under the laws of the British Virgin Islands following the consummation of the merger. Following the Vahanna Special Meeting, pursuant to SEC rules and regulations, Vahanna will file a Form 8-K announcing the results of the meeting, which will include a statement as to the jurisdiction of incorporation of New Roadzen.

To address certain of Roadzen’s business and accounting considerations, the parties agreed that New Roadzen would continue as a British Virgin Islands business company after the merger. If so, then so long as public holders of Vahanna’s Class A Ordinary Shares in the aggregate elected to redeem enough shares for the merger to result in a Deemed Domestication by virtue of an 80% Inversion, the merger would be structured in a tax-efficient manner for Roadzen shareholders. However, if New Roadzen retained its non-U.S. incorporation, and public holders of Vahanna’s Class A Ordinary Shares did not elect to redeem enough shares for the merger to result in a Deemed Domestication by virtue of an 80% Inversion (as defined in “Material U.S. Federal Income Tax Considerations — Tax Residency of Vahanna for U.S. Federal Income Tax Purposes”), then to mitigate potential U.S. tax consequences to Roadzen shareholders the parties also agreed that Vahanna would in that event change its jurisdiction of incorporation to become a corporation incorporated under the laws of the State of Delaware. As a result, in all events, from a U.S. federal income tax perspective, Vahanna is expected to be deemed to convert from a non-U.S. corporation to a U.S. corporation either at the end of the day immediately preceding the merger, in the case of the Deemed Domestication, or on the date that the certificate of domestication is filed with the Delaware Secretary of State, but in all events at least one (1) business day before the merger. If Vahanna failed to qualify as a domestic corporation for U.S. federal income tax purposes in advance of the merger, either because of a failed 80% Inversion or because it ultimately did not undergo the Domestication, the merger would not be able to qualify for the intended tax treatment (as described in “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — The Deemed Domestication” and “— The Domestication”).

QUESTIONS AND ANSWERS ABOUT THE VAHANNA SPECIAL MEETING

xi

These proposals, along with Proposal No. 2, will only be presented and voted upon in the event that holders elect to redeem 12,000,000 or more Class A Ordinary Shares, par value $0.0001 per share, in connection with the Vahanna Special Meeting (or at least approximately 48% of the issued and outstanding Vahanna ordinary shares, which is comprised of 20,010,000 Class A Ordinary Shares and 5,002,500 Class B ordinary shares, par value $0.0001 per share (collectively, the “Vahanna ordinary shares”)). If not, we will present Proposals No. 4 through 6D.

xii

These proposals, along with Proposal No. 5, will only be presented and voted upon in the event that elections to redeem Class A Ordinary Shares in connection with the Vahanna Special Meeting are less than 12,000,000 Class A Ordinary Shares (or less than approximately 48% of the issued and outstanding Vahanna ordinary shares).

The adoption and approval of the Business Combination Proposal and the Domestication Proposal is required under Vahanna’s Existing Charter and the approval of the merger is required under Vahanna’s Existing Charter. The approval of the Nasdaq Proposal is required under Nasdaq Rules. In addition, approval of such proposals by Vahanna shareholders is also a condition to the closing of the merger under the merger agreement.

If Vahanna shareholders fail to approve the Business Combination Proposal, the Nasdaq Proposal or, as applicable, the Charter Proposal, Domestication Proposal or Delaware Charter Proposal, the merger will not occur.

It is important to note that if Vahanna shareholders fail to approve the Business Combination Proposal, the Nasdaq Proposal or, as applicable, the Charter Proposal, the Domestication Proposal or the Delaware Charter Proposal, the merger will not occur.

On November 26, 2021, Vahanna completed its IPO. A total of $204,102,000, comprised of $195,463,500 of the proceeds from the IPO (including aggregate fees of approximately $6,525,000 as deferred underwriting commissions) and $8,638,500 of the proceeds from the concurrent sale of the Private Placement Warrants, was placed in a trust account (the “Trust Account”), maintained by Continental Stock Transfer & Trust Company (“CST”), acting as trustee. Since the IPO, Vahanna’s activity has been limited to the evaluation of business combination candidates.

At the heart of its mission is its commitment to create transparency, efficiency, and a seamless experience for the millions of end customers who use its products through its insurer, original automotive equipment manufacturer (“OEM”), and fleet (such as trucking, delivery, and commercial fleets) partners. Roadzen seeks to accomplish this by combining computer vision, telematics and AI with continually updated data sources to provide a more efficient, effective and informed way of building auto insurance products, assessing damages, processing claims and improving driver safety.

Insurers across the world use Roadzen’s technology to launch new auto insurance products, manage risk better and resolve claims faster. These products are built with dynamic underwriting capabilities, application programming interface (“API”)-led distribution and real-time claims processing.

Roadzen has been recognized as a top innovator in the insurtech space by Forbes and Financial Express (India).

Based on its due diligence investigations of Roadzen and the industry in which it operates, including the financial and other information provided by Roadzen in the course of their negotiations in connection with the merger agreement, Vahanna believes that Roadzen aligns well with the objectives laid out in its investment thesis which focused on identifying a high-growth, new technology company with a strong connection to India and that is both vertically focused (e.g., insurtech), concentrating in a niche market, and horizontally focused (e.g., AI Analytics, IoT, etc.), spreading across various industries.

As a result, Vahanna believes that a merger with Roadzen will provide Vahanna shareholders with an opportunity to participate in the ownership of a publicly listed company with significant growth potential at an attractive valuation. See the section titled “The Merger — Recommendation of the Vahanna Board of Directors and Reasons for the Merger.”

Notwithstanding the foregoing, a holder of Class A Ordinary Shares, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Class A Ordinary Shares, without the prior written consent of Vahanna.

Holders of the outstanding public warrants of Vahanna do not have redemption rights with respect to such warrants in connection with the transactions contemplated by the Business Combination Proposal.

Under Vahanna’s Existing Charter, the merger may be consummated only if Vahanna has at least $5,000,001 of net tangible assets after giving effect to all holders of Class A Ordinary Shares that properly demand redemption of their shares for cash.

Any request for redemption, once made by a holder of Class A Ordinary Shares, may not be withdrawn once submitted to Vahanna unless the directors determine (in their sole discretion) to permit the withdrawal of such redemption request. If you deliver your shares for redemption to Vahanna’s transfer agent and later decide prior to the Vahanna Special Meeting not to elect redemption, subject to approval by Vahanna’s directors, you may request that Vahanna’s transfer agent return the shares (physically or electronically).

Any corrected or changed proxy card or written demand of redemption rights must be received by Vahanna’s transfer agent prior to the vote taken on the Business Combination Proposal at the Vahanna Special Meeting. No demand for redemption will be honored unless the holder’s stock has been delivered (either physically or electronically) to the transfer agent no later than 5:00 p.m., New York time, two (2) business days prior to the vote at the Vahanna Special Meeting.

If a holder of Class A Ordinary Shares properly makes a request for redemption and the Class A Ordinary Shares are delivered as described to Vahanna’s transfer agent as described herein, then, if the merger is consummated,

xv

Vahanna will redeem these shares for a pro rata portion of the funds deposited in the Trust Account. If you exercise your redemption rights, then you will be exchanging your Class A Ordinary Shares for cash.

For a discussion of the material U.S. federal income tax considerations for holders of Class A Ordinary Shares with respect to the exercise of these redemption rights, see the sections titled “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — Redemption of Class A Ordinary Shares Following the Merger” and “— U.S. Federal Income Taxation of Non-U.S. Holders — Redemption of Class A Ordinary Shares Following the Merger.”

Effect of Redemptions and Underwriting Fees on Book Value Per Share

As of the date of this proxy statement/prospectus, Vahanna had warrants to purchase an aggregate of 18,643,500 New Roadzen Ordinary Shares, comprising 10,005,000 public warrants and 8,638,500 Private Placement Warrants. The likelihood that these Vahanna Warrants will be exercised increases if the trading price of New Roadzen Ordinary Shares exceeds the exercise price of the Vahanna Warrants. The exercise price of the Vahanna Warrants is $11.50 per share.

Based on the closing price of $0.034 per warrant on Nasdaq on June 29, 2023, the most recent practicable date prior to the date of this proxy statement/prospectus, the public warrants and the Private Placement Warrants have an aggregate

xvii

market value of approximately $633,879 (including approximately $340,170 for the public warrants that may be retained by redeeming shareholders in the maximum redemption scenario). However, there is no assurance that the Vahanna Warrants will ever be in the money following the time they become exercisable and prior to their expiration, and as such, the warrants may expire worthless.

To the extent the Vahanna Warrants are exercised, additional New Roadzen Ordinary Shares will be issued, which will result in dilution to the non-redeeming Vahanna public shareholders and increase the number of shares eligible for resale in the public market. The dilution, as a percentage of outstanding shares, caused by the exercise of the Vahanna Warrants will increase if a large number of Vahanna public shareholders elect to redeem their Class A Ordinary Shares in connection with an initial business combination. Holders of Vahanna Warrants do not have a right to redeem the warrants. Further, the redemption of Class A Ordinary Shares without any accompanying redemption of the public warrants will increase the dilutive effect of the exercise of public warrants. Sales of substantial numbers of shares issued upon the exercise of Vahanna Warrants in the public market, or the potential that such warrants may be exercised and sold in the public market, could also adversely affect the value of New Roadzen Ordinary Shares. See the section titled “Summary — Ownership of New Roadzen” which details the post-closing capitalization of New Roadzen on a fully diluted basis, including the effects of the exercise of issued and outstanding public warrants and Private Placement Warrants.

On each of May 24, 2023, June 22, 2023 and July 24, 2023, pursuant to the Existing Charter, the Sponsor caused to be deposited an aggregate of $660,330 into the Trust Account to extend the deadline by which Vahanna must consummate an initial business combination from May 26, 2023 to June 26, 2023, June 26, 2023 to July 26, 2023 and July 26, 2023 to August 26, 2023, respectively. In addition, Vahanna has filed a preliminary proxy statement to call an extraordinary general meeting of shareholders regarding a proposal to provide the Vahanna board of directors the ability to further extend the business combination period up to twelve additional times for one month each time, from May 26, 2023 to May 26, 2024.

Shareholders who choose to participate in the Vahanna Special Meeting can vote their shares electronically during the meeting via live audio webcast by visiting https://www.cstproxy.com/vahannatech/sm2023.

You will need the control number that is printed on your proxy card to enter the Vahanna Special Meeting. Vahanna recommends that you log in at least fifteen (15) minutes before the meeting to ensure you are logged in when the Vahanna Special Meeting starts.

If your shares are held in “street name” through a broker, bank or other nominee, your broker, bank or other nominee will send you separate instructions describing the procedure for voting your shares. “Street name” shareholders who wish to vote at the Vahanna Special Meeting will need to obtain a proxy form from their broker, bank or other nominee.

You can pre-register to attend the virtual Vahanna Special Meeting three (3) days prior to the meeting date starting August 22, 2023 at 12:00 a.m. New York time. Enter the URL address into your browser https://www.cstproxy.com/vahannatech/sm2023, enter your control number, name and email address. Once you pre-register you can vote or enter questions in the chat box. At the start of the meeting you will need to re-login using your control number and will also be prompted to enter your control number if you vote during the meeting. Vahanna recommends that you log in at least 15 minutes before the meeting to ensure you are logged in when the Vahanna Special Meeting starts.

Beneficial shareholders, who own their investments through a bank or broker, will need to contact CST to receive a control number. If you plan to vote at the Vahanna Special Meeting you will need to have a legal proxy from your bank or broker or if you would like to join and not vote CST will issue you a guest control number with proof of ownership. Either way you must contact CST for specific instructions on how to receive the control number. We can be contacted at the number or email address above.

xx

Please allow up to 72 hours prior to the meeting for processing your control number.

If you do not have Internet capabilities, you can listen to the meeting by dialing 1-800-450-7155 (toll-free within the United States and Canada) or +1 857-999-9155 (outside of the United States and Canada, standard rates apply). When prompted enter the pin number 9896576#. This is listen-only, meaning you will not be able to vote or enter questions during the meeting.

Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy card directly to Vahanna or by voting online at the Vahanna Special Meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Under Nasdaq rules, brokers who hold shares in “street name” for a beneficial shareholder of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial shareholders. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that Nasdaq determines to be “non-routine” without specific instructions from the beneficial shareholders. We believe the proposals presented to the shareholders at the Vahanna Special Meeting will be considered non-routine and, therefore, your broker, bank, or other nominee cannot vote your shares without your instruction on any of the proposals presented at the Vahanna Special Meeting. If you do not submit voting instructions, your broker, bank, or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares. This indication that a broker, bank, or nominee is not voting your shares is referred to as a “broker non-vote.” Your bank, broker, or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide.

xxi

If you transfer your Class A Ordinary Shares prior to the Record Date, you will have no right to vote those shares at the Vahanna Special Meeting or redeem those shares for a pro rata portion of the proceeds held in the Trust Account.

For purposes of approval, a failure to vote or an abstention will have no effect on the Business Combination Proposal, the Charter Proposal, the Governance Proposals, the Domestication Proposal, the Delaware Charter Proposal, the Delaware Governance Proposals, the Nasdaq Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal.

You may do this in one of three ways:

If you are a shareholder of record of Vahanna and you choose to send a written notice or to mail a new proxy, you must submit your notice of revocation or your new proxy to Vahanna Tech Edge Acquisition I Corp., 1230 Avenue of the Americas, 16th Floor, New York, NY 10020, and it must be received at any time before the vote is taken at the Vahanna Special Meeting. Any proxy that you submitted may also be revoked by submitting a new proxy by mail, or online or by telephone, not later than 11:59 p.m. New York time on August 24, 2023, or by voting online at the Vahanna Special Meeting. Simply attending the Vahanna Special Meeting will not revoke your proxy. If you have instructed a broker, bank or other nominee to vote your Vahanna ordinary shares, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your vote.

xxii

If you fail to take any action with respect to the Vahanna Special Meeting and the merger is not approved, you will continue to be a shareholder of Vahanna while Vahanna searches for another target business with which to complete a business combination.

There is currently uncertainty concerning the applicability of the Investment Company Act to a SPAC. It is possible that a claim could be made that we have been operating as an unregistered investment company, including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act, based on the current views of the SEC. The funds in the Trust Account have historically, since the Company’s IPO, been held only in U.S. government securities within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or money market funds meeting certain conditions of Rule 2a-7 of the Investment Company Act, to mitigate the risk of being viewed as operating as an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act). However, on June 12, 2023, prior to the date that is 24 months after the effective date of the registration statement relating to our IPO (November 22, 2023), we instructed Continental Stock Transfer & Trust Company, the trustee with respect to the Trust Account, to liquidate the U.S. government securities or money market funds held in the Trust Account and thereafter to hold all funds in the Trust Account in an interest-bearing bank deposit account until the earlier of consummation of our initial business combination or our liquidation. Interest on bank deposit accounts is variable and such accounts currently yield interest of approximately 4.25% per annum. Following the liquidation of the Trust Account assets, if we are unable to

xxiii

achieve more than minimal interest, on the funds held in the Trust Account, the dollar amount our public shareholders would otherwise receive upon any redemption or liquidation of the Company would be less than if the assets in the Trust Account remained in U.S. government securities or money market funds.

In addition, even prior to the date that is 24 months after the effective date of the registration statement relating to our IPO, we may be deemed to be an investment company. The longer that the funds in the Trust Account are held in short-term U.S. government securities or in money market funds invested exclusively in such securities, even prior to the date that is 24 months after the effective date of the registration statement, there is a greater risk that we may be considered an unregistered investment company, in which case we may be required to liquidate. Accordingly, we determined, in our discretion, to liquidate the securities held in the Trust Account prior to the 24-month anniversary, and currently hold all funds in the Trust Account in an interest-bearing bank deposit account, which may further reduce the dollar amount our public shareholders would receive upon any redemption or our liquidation. For more information, see the section entitled “Risk Factors — If we are deemed to be an investment company for purposes of the Investment Company Act, we may be forced to abandon our efforts to complete an initial business combination and instead be required to liquidate the Company. To mitigate the risk of that result, we instructed Continental Stock Transfer & Trust Company to liquidate the securities held in the Trust Account and currently hold all funds in the Trust Account in a bank deposit account.”
