Treat the request as a negotiation with your lead before it becomes a request to your SAFE holders. Find out exactly what the lead wants and why, model it, and try the fixes that don't reopen signed deals, such as a smaller pool, a different price or a pro rata cutback. If you still need an amendment, the YC post-money SAFE lets the company amend with each holder, or with a majority-in-interest of the SAFEs that share the same cap and discount, as long as every holder in that group is asked and all are treated the same. Ask honestly, show the numbers, and remember that these early backers stay on your cap table and in your network long after the round closes.
Key takeaways
Usually it's the math. Several SAFE rounds at low caps can convert into a large share of the company, and because a priced-round term sheet usually counts the converting SAFEs inside the pre-money valuation, the founders absorb that dilution, not the new investors. See Valuation Cap. A lead that thinks the founders will own too little after the round to stay motivated has two choices: pay a higher pre-money valuation, or ask the SAFE holders to give some ownership back. The second costs the lead nothing.
The asks come in a few forms. The most common is raising the cap on the earliest, cheapest SAFEs so they convert into fewer shares. A lead with an ownership target may ask holders to waive or cut back their pro rata side letters, so existing investors don't take part of the round it wants. Leads also ask MFN holders to waive their MFN, or ask SAFE holders to take a different or junior series of preferred stock instead of the shadow series the SAFE provides.
Some requests don't need an amendment at all. The YC post-money SAFE already requires holders, at conversion, to sign the same transaction documents the new investors sign, with customary limits on their drag-along obligations, and it gives them preferred stock identical to the new investors' apart from price-based terms. Anything beyond that changes their deal.
Separate a real reset from a squeeze. If the company missed its plan and the round only works with a change, most early backers will engage. If the round can close as proposed and the change only moves value to the lead or the founders, push back on the lead before you push on your investors.
Get the request in writing and in numbers. Ask the lead what ownership it is solving for, the founders' or its own, and what result would satisfy it. Build a pro forma cap table showing the round as proposed, as the lead wants it and with each alternative below. Pull your SAFE schedule and group the SAFEs by cap and discount, because that's how amendment votes are counted. Mark which holders have pro rata side letters or MFN rights.
Then negotiate with the lead first, using the alternatives below. Before you share any round terms with SAFE holders, read the term sheet's confidentiality clause and agree with the lead what you can disclose. Term sheets often make that clause binding even though the rest isn't. The NVCA model term sheet does, and it allows sharing with stockholders, which SAFE holders aren't yet.
Section 5(a) of the YC post-money SAFE lets the company amend, waive or modify any provision with the written consent of the company and either the investor or a majority-in-interest of all outstanding SAFEs with the same post-money valuation cap and discount rate. Majority-in-interest means the holders of more than 50% of that group's total purchase amount. SAFEs that lack a cap or a discount are treated as the same on that term, so, for example, all uncapped MFN SAFEs form one group.
The majority route has three conditions. It can't change any holder's purchase amount. The company must solicit the consent of every holder in the group, including those who won't sign. And the amendment must treat every holder in the group the same way. A side payment or sweetener for the large holder who signs, but not for the others, breaks that condition. On YC's MFN form, the MFN provision itself is also off limits to a majority, so waiving an MFN takes each holder's own consent.
Each cap group stands alone: a majority of one group can't bind another.
YC's pro rata side letter has its own amendment clause. It can be changed with the investor's consent, or with the consent of holders of a majority of the shares issued on conversion of the SAFEs held by investors with pro rata side letters on the same form, treating them all the same. The company must then promptly notify any investor that didn't consent.
Paper it simply. The board approves the amendment along with the financing. The company and the consenting holders sign a short amendment that changes only the agreed term, everyone in the group gets notice, and the SAFE schedule is updated before closing, because the SAFEs convert at the initial closing on whatever terms they have then. Using the form's own amendment clause, and changing only the agreed term, keeps the rest of the YC SAFE standard.
Directors of a Delaware corporation owe fiduciary duties to the corporation and its stockholders. SAFE holders aren't stockholders until conversion, and the YC form says so. There's little case law on SAFEs, but by analogy, Delaware's Supreme Court has held that convertible debenture holders have contract rights, not fiduciary claims, until they convert (Simons v. Cogan, 1988). A SAFE isn't debt, so the fit isn't exact, but a SAFE holder's rights are likely set by the SAFE. Their protection is the amendment clause's conditions and the implied covenant of good faith and fair dealing, which under Delaware law bars arbitrary or unreasonable conduct that deprives the other party of the fruits of its bargain. It only fills gaps and can't override the SAFE's terms.
The board still owes the company and its stockholders an informed decision on the financing as a whole, The founders on the board benefit when SAFE holders give ground, but as stockholders alongside every other stockholder, which isn't a conflict by itself. If a director or officer also holds SAFEs, or a director is affiliated with the lead, disclose that interest to the board and have the disinterested directors approve. See Fiduciary Duties of Startup Founders.
Give every holder in the group the same package: what the lead asked for and why, the round terms you're allowed to share, a pro forma cap table showing their ownership with and without the change, what the founders and the lead are contributing, and the deadline. Say plainly that the founders benefit from the change. Be accurate about the stakes. If the lead has said it will walk, say so. If it hasn't, don't. A misleading request to give up rights can lead to fraud claims, and because a SAFE is a security, the securities laws' anti-fraud rules may apply too.
Size the pool to the hiring plan. A pool counted in the pre-money is paid for by the founders and the converting SAFE holders. If the lead wants 10% and your hire-by-hire plan supports 7.5%, the difference goes to the existing holders. See Negotiating an Option Pool.
Move the price or the pool's placement. If the lead's concern is founder ownership, a higher pre-money valuation, or putting part of the pool increase in the post-money, fixes it at the lead's expense rather than the angels'. The lead will resist, but it's the honest version of its ask.
Cut back pro rata instead of economics. If the lead's problem is allocation, ask holders with pro rata rights to take less of the round rather than give up conversion shares. That costs them part of a future option, not ownership they've already paid for. See Pro Rata Rights.
Trim an oversized pool early. Company Capitalization counts the unissued pool, so cancelling genuine excess well before the term sheet modestly reduces the SAFE conversion shares. Shrinking the pool just before the round, only to rebuild it in the round, invites a dispute.
Let the founders carry some of it. Founders with 46% of a well-funded company and loyal early backers may be better off than founders with 50% and a reputation for squeezing their angels.
Example. A company has 8,000,000 founder shares and a 1,000,000-share option pool. Before its Series A it raised two groups of post-money SAFEs. Group A is five angels who put in $500,000 at a $5,000,000 cap: one check of $200,000, two of $100,000 and two of $50,000. Group B is $2,000,000 at a $12,500,000 cap, with YC pro rata side letters. The lead offers $8,000,000 at a $24,000,000 pre-money valuation, so it owns 25% after closing, and requires a 10% post-money pool counted in the pre-money.
Group A owns 10% and Group B 16% of the Company Capitalization, 26% together, so Company Capitalization is 9,000,000 ÷ 74%, about 12,162,162 shares. Group A converts into about 1,216,216 shares at about $0.4111 each, Group B into about 1,945,946 shares at about $1.0278, and the Series A price is about $1.8634. The founders finish at about 46.6%.
The lead wants the founders at 50% and asks Group A to move its cap to $10,000,000. Group A's share of Company Capitalization falls to 5%, Company Capitalization falls to 9,000,000 ÷ 79%, about 11,392,405 shares, and Group A converts into about 569,620 shares. Group B's terms don't change. It still owns 16% of the now smaller Company Capitalization, about 1,822,785 shares. The Series A price rises to about $2.0015 and the founders reach about 50.0%. At the Series A price, Group A's stake falls from about $2,266,000 to about $1,140,000, roughly half.
A middle path: the founders show the lead that the hiring plan needs a 7.5% pool, not 10%, and Group A agrees to a $7,000,000 cap. The founders reach about 50.4%, and Group A keeps about 5.3%, worth about $1,687,000.
| As proposed | Lead's ask: Group A cap to $10M | Middle path: 7.5% pool, Group A cap to $7M | |
|---|---|---|---|
| Founders | 46.6% | 50.0% | 50.4% |
| Group A SAFE holders | 7.1% | 3.6% | 5.3% |
| Group B SAFE holders | 11.3% | 11.4% | 11.8% |
| Series A lead | 25.0% | 25.0% | 25.0% |
| Option pool | 10.0% | 10.0% | 7.5% |
| Series A price per share | $1.8634 | $2.0015 | $2.0168 |
| Group A stake at the Series A price | about $2,266,000 | about $1,140,000 | about $1,687,000 |
To amend Group A, the company needs holders of more than $250,000 of its $500,000. The $200,000 holder and one $100,000 holder, $300,000 together, can approve the change for all five, but only if the company asked all five and the amendment treats them the same. Group B doesn't vote, because its SAFEs don't change. If the lead also wants its full $8,000,000 allocation, remember that Group B's side letters give it the right to buy 16% of the Series A shares being sold, or $1,280,000. Cutting that back needs consent under the side letters: each holder's own, or holders of a majority of Group B's conversion shares, treating all alike.
Your earliest investors backed you when the company was riskiest, on a standard form and largely on trust. They're your references for the next round. Many will agree because a failed round is worse for them too, and they'll remember how you handled it.
When you do ask, call the largest holders yourself before anything goes out in writing, then send everyone in the group the same package at the same time. Offer something where you can, such as a smaller change than the lead first asked for or a modest allocation in the round. Give a reasonable deadline, a week or two rather than 48 hours. And keep the conversation yours. Your lead shouldn't be running a pressure campaign on your investors.
