Y CombinatorUpdated 17 Oct 2025

This Pro Rata Agreement grants an investor the right to purchase a pro rata share of Standard Preference Shares in a future equity financing round. This right is connected to an initial investment made through a Simple Agreement for Future Equity (SAFE) and allows the investor to maintain their ownership percentage.

[company name]

PRO RATA AGREEMENT

This agreement (this “Agreement”) is entered into on or about [date of safe] in connection with the purchase by [investor name] (the “Investor”) of that certain simple agreement for future equity with a “Post-Money Valuation Cap” (the “Investor’s Safe”) issued by [company name] (the “Company”) on or about the date of this Agreement. As a material inducement to the Investor’s investment, the Company agrees to the provisions set forth in this Agreement. Capitalized terms used herein shall have the meanings set forth in the Investor’s Safe.

The Investor shall have the right to purchase its pro rata share of Standard Preference Shares being sold in the Equity Financing (the “Pro Rata Right”). Pro rata share for purposes of this Pro Rata Right is the ratio of (x) the number of Capital Shares issued from the conversion of all of the Investor’s Safes with a “Post-Money Valuation Cap” to (y) the Company Capitalization. The Pro Rata Right described above shall automatically terminate upon the earlier of (i) the initial closing of the Equity Financing; (ii) immediately prior to the closing of a Liquidity Event; or (iii) immediately prior to the Dissolution Event.

Neither this Agreement nor the rights contained herein may be assigned, by operation of law or otherwise, by Investor without the prior written consent of the Company; provided, however, that this Agreement and/or the rights contained herein may be assigned without the Company’s consent by the Investor to any other entity who directly or indirectly, controls, is controlled by or is under common control with the Investor, including, without limitation, any general partner, managing member, officer or director of the Investor, or any venture capital fund now or hereafter existing which is controlled by one or more general partners or managing members of, or shares the same management company with, the Investor.

Any provision of this Agreement may be amended, waived or modified upon the written consent of the Company and either (i) the holders of a majority of shares of Capital Shares issued from all Safes converted in connection with the Equity Financing held by the Investor and other Safe holders with Pro Rata Rights pursuant to agreements on the same form as this Agreement, provided that such amendment, waiver or modification treats all such holders in the same manner, or (ii) the Investor. The Company will promptly notify the Investor of any amendment, waiver or modification that the Investor did not consent to. The choice of law governing any dispute or claim arising out of or in connection with this Agreement and the submission to jurisdiction of the parties hereunder shall be consistent with that set forth in the Investor’s Safe.

IN WITNESS WHEREOF, the undersigned have caused this Agreement to be duly executed and delivered.

Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.

It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.
