A valuation cap is the ceiling valuation at which a SAFE note or convertible note converts into equity during a future priced round. It exists to reward early investors for taking on more risk by guaranteeing them a minimum effective price per share, even if the company's valuation increases dramatically before conversion.
How the cap works
When a priced round occurs, the SAFE or convertible note converts at whichever gives the investor a lower price per share (i.e., more shares):
- The valuation cap price — calculated by dividing the cap by the fully diluted share count
- The discount price — the priced round's price per share minus the discount percentage
Example
An investor puts $200K into a SAFE with a $6M post-money valuation cap. The startup later raises a Series Seed at a $15M pre-money valuation with a price per share of $3.00.
- Cap price: if post-money cap is $6M and there are 6M fully diluted shares, the cap price is $1.00/share
- Round price: $3.00/share
- The investor converts at $1.00/share, receiving 200,000 shares instead of the 66,667 they would get at the round price — a 3x improvement
Post-money vs. pre-money caps
This distinction is crucial:
- Post-money cap (YC standard): the cap includes the SAFE investment itself, giving the investor a clear ownership percentage. A $200K SAFE on a $6M post-money cap = exactly 3.33% ownership.
- Pre-money cap: the cap excludes the SAFE investment, meaning the investor's actual ownership depends on total SAFE amounts raised — less predictable for both sides.
2026 cap benchmarks
- Pre-seed: $3–8M post-money cap
- Seed: $8–15M post-money cap
- Between rounds / bridge: often set at a 10–30% discount to the last priced round's valuation
Negotiation dynamics
Founders want the highest possible cap (less dilution), while investors want the lowest possible cap (more ownership). The cap should reflect the company's current stage and risk level, not its aspirational future valuation. Setting a cap too high can backfire — if the next round prices below the cap, the cap provides no benefit to the investor, making the SAFE economically equivalent to common stock without the governance rights.
