SAFE (Simple Agreement for Future Equity)
This Safe is one of the forms available at https://www.ycombinator.com/documents and the Company and the Investor agree this is the form used.
THIS CERTIFIES THAT in exchange for the payment by {{INVESTOR_NAME}} (the "Investor") of ${{PURCHASE_AMOUNT}} (the "Purchase Amount") on or about {{EFFECTIVE_DATE}}, {{COMPANY_NAME}}, a {{STATE_OF_INCORPORATION}} corporation (the "Company"), issues to the Investor the right to certain shares of the Company's capital stock, subject to the terms described below.
The "Post-Money Valuation Cap" is ${{VALUATION_CAP}}.
[FOUNDER ANNOTATION — CAP]
This is the number you negotiate hardest. Post-money cap = investor's max ownership at conversion is Purchase Amount / Cap. A ${{PURCHASE_AMOUNT}} check on a ${{VALUATION_CAP}} cap locks in that investor's stake regardless of how much more SAFE money you raise after. Every extra SAFE dilutes YOU, not them. If the round is growing, push the cap up with it.
See Section 2 for certain additional defined terms.
1. Events
(a) Equity Financing. If there is an Equity Financing before the termination of this Safe, on the initial closing of such Equity Financing, this Safe will automatically convert into the number of shares of Safe Preferred Stock equal to the Purchase Amount divided by the Conversion Price.
The "Conversion Price" will be the lower of: (1) the Safe Price or (2) the Discount Price.
[FOUNDER ANNOTATION — DISCOUNT]
In the Valuation-Cap-only variant there is no Discount Price — strike it if the investor asks for both. In the Cap + Discount variant the market discount is 20%. Anything beyond 20% is outside market and you should push back. Never sign BOTH an aggressive cap AND a 25%+ discount without running the dilution math in a cap table tool first.
(b) Liquidity Event. If there is a Liquidity Event before the termination of this Safe, the Investor will automatically receive from the Company a cash payment equal to the Purchase Amount OR a number of shares of Common Stock equal to the Purchase Amount divided by the Liquidity Price, whichever the Investor elects.
(c) Dissolution Event. If there is a Dissolution Event before this Safe terminates, the Company will pay an amount equal to the Purchase Amount, due and payable immediately prior to the Dissolution Event.
2. Definitions
"Most Favored Nation Amendment Provision." If the Company issues any Subsequent Convertible Securities prior to the termination of this Safe, the Company will promptly provide the Investor with written notice thereof, together with a copy of all documentation relating to such Subsequent Convertible Securities.
[FOUNDER ANNOTATION — MFN]
MFN lets the investor retroactively swap in better terms if a later SAFE has them. It's standard in the Uncapped MFN variant and sometimes layered onto Valuation Cap SAFEs by early, small checks. Granting MFN on a priced cap SAFE is unusual and you can usually push back: "We're running a uniform round at one cap, so MFN isn't necessary here." If the investor insists, limit the MFN window (e.g., only applies to SAFEs closed within 90 days and only to economic terms, not governance).
[FOUNDER ANNOTATION — PRO-RATA SIDE LETTER]
Pro-rata is NOT in the standard YC post-money SAFE. It comes as a separate side letter. Sign this ONLY for investors who are writing lead-sized checks ({{PRO_RATA_THRESHOLD}} or more) or who bring real strategic value. Signing pro-rata side letters for every $25k angel creates a cap-table mess at your Series A — the lead will ask you to clean it up and some of your angels will feel burned. Use the threshold. Say no politely to the rest.
5. Miscellaneous
(a) Any provision of this Safe may be amended, waived or modified by written consent of the Company and either (i) the Investor or (ii) the majority-in-interest of all then-outstanding Safes with the same "Post-Money Valuation Cap"...
IN WITNESS WHEREOF, the undersigned have caused this Safe to be duly executed and delivered.

Variables · fill before sending
- COMPANY_NAMEExact legal name as on the certificate of incorporation (e.g., Acme Labs, Inc.)
- STATE_OF_INCORPORATIONUsually Delaware for US C-corps. Must match your COI.
- INVESTOR_NAMEFull legal name of the investor or their fund entity, not the partner's personal name
- PURCHASE_AMOUNTDollar amount of this specific SAFE, numerals only (e.g., 250000)
- VALUATION_CAPPost-money cap in dollars. Typical 2024 seed range: 8M to 20M.
- EFFECTIVE_DATEDate of wire or countersignature, whichever is later
- FOUNDER_NAMEName of the officer signing (usually CEO)
- FOUNDER_TITLESignatory title, e.g., Chief Executive Officer
- PRO_RATA_THRESHOLDMinimum check size above which you'll grant pro-rata via side letter (e.g., $250k)
How to use it
- Use the YC generator, not a retyped copy. Pull the live form from Y Combinator's documents page or use the Cooley GO YC SAFE generator so you get the current form text. Paste your annotations into the DOCX you download, not into a redraft.
- Pick one of three US variants before talking terms. YC publishes three post-money forms: Valuation Cap no Discount, Discount no Valuation Cap, and Uncapped MFN. Decide which one you're offering before the first investor conversation so you're not negotiating the instrument and the numbers at the same time.
- Model dilution before you sign. Post-money SAFEs lock in investor ownership, which means every subsequent SAFE you raise at the same or higher cap dilutes YOU only, not the prior investors. Run the cap-table math in Carta or a spreadsheet before agreeing to a cap.
- Don't stack aggressive discount on top of aggressive cap. The typical 2024 discount is 20%. If an investor asks for a 25%+ discount and a below-market cap, you're being double-dipped. Pick one lever to move.
- Set a pro-rata threshold and hold it. Decide upfront the minimum check size that earns a pro-rata side letter (commonly $100k to $250k at seed). Granting it to every angel makes your Series A messier than it needs to be.
- Get a lawyer to review before the first countersignature. Cooley GO is explicit that founders should seek legal review when choosing between pre-money and post-money forms. A one-hour review at seed saves a cap-table crisis at Series A.
