What is Valuation cap?

The maximum company valuation at which a SAFE or convertible note converts into equity; it sets the effective price early investors pay and, with the raise size, how much of the company you have sold.

Why does Valuation cap matter to a founder?

The cap is the price of a SAFE round even though nobody calls it that. Raise $1M on a $10M post-money cap and you have sold about 10%; raise $3M on the same cap and you have sold 30%. Founders scale the raise without scaling the cap, or stack SAFEs at several caps, and only see the total at conversion. The cap has to be sized to the raise.

What are the common mistakes with Valuation cap?

Keeping the same cap while raising three times as much. Raising $1.5M at a $6M cap, which is roughly 25% dilution, too much for one early round. Ignoring that an unused option pool sits in the conversion denominator and inflates the dilution. Confusing the discount rate with the discount: 90% discount rate means a 10% discount.

A valuation cap is the ceiling on the price at which a SAFE converts. If the priced round values the company above the cap, SAFE holders convert as if the valuation were the cap, and get more shares per dollar than the new investors. If the round comes in below the cap, they convert at the round price (or a discount to it, if the SAFE has one). The cap is therefore the effective price of the SAFE money.

Why it matters

Scale the cap to the raise, or the dilution gets away from you.

The mechanics quoted in the room: $1M on a $10M post-money cap is about 10%, fine. Raising $3M at that same cap hands over 30%; push the cap toward $15M to keep the round near 20%. Carta’s published data, cited in May 2026, puts the pre-seed median post-money cap near $10M, and a $3M SAFE raise implies something more like an $18–20M cap. Sensible dilution per early round is 10–20%.

Two mechanics that quietly worsen the math: an unused 20% option pool makes every SAFE convert against a bigger share count (keep the pool near 10%), and a “90% discount rate” in YC SAFE language means a 10% discount, which founders have drafted wrong without knowing which one they meant.

Where founders get it wrong

Raising more without raising the cap.
Accepting a low cap for a large check.
Forgetting the option pool in the denominator.
Drafting the wrong discount number.
