SAFE vs Priced Round
The instrument you raise on decides how much you dilute, when, and how much control you trade - often more than the headline valuation does. Founders who treat the SAFE as "free money now" get a nasty surprise at the priced round. This skill makes the choice deliberate.
When to use this skill
Use it during [[fundraising-stage-selector]] when sizing the round and before signing anything. Model every choice through [[cap-table-manager]] so the dilution is real, not abstract.
The instruments
SAFE (Simple Agreement for Future Equity)
- No interest, no maturity, converts to equity at the next priced round.
- Fast (signable in days, legal cost near zero on standard docs), cheap, standard (Y Combinator post-money SAFE). Dominant at pre-seed and seed.
- Post-money SAFE: the investor's percentage is fixed at signing; founders absorb the dilution of later SAFEs and the new-round pool. This is the common form - know that you dilute around it.
- Pre-money SAFE (older): SAFE holders dilute each other; murkier math.
Convertible note
- Like a SAFE but it is debt: carries interest (commonly 2-8%) and a maturity date (commonly 18-24 months). Rare outside specific situations; the maturity date is a real risk if the next round slips.
Priced equity round
- You sell shares at an agreed valuation now. Sets a real price, a board seat, and full terms (preferences, protective provisions). More legal cost and time - typically several weeks to close and tens of thousands of dollars in combined legal fees, versus days and near-zero for a standard SAFE.
- Standard at Series A; also common at larger seeds.
The SAFE terms that decide your dilution
- Valuation cap: the maximum valuation at which the SAFE converts. Lower cap = more dilution for you, more upside for the investor. The most negotiated term. Quick check: on a post-money SAFE, amount raised ÷ post-money cap = the percentage you just sold ($500k on a $5M cap is 10%, full stop).
- Discount: a percentage off the next round's price (typically 10-20%).
- Cap vs discount: investors take whichever is better for them at conversion. Model both.
- MFN (most-favored-nation): a SAFE holder gets the best terms you later grant. Stacking MFN SAFEs can quietly ratchet up everyone's terms.
Choosing
- SAFE when: speed matters, you are pre/early-seed, you have strong investor demand and want to avoid setting a price too early.
- Priced round when: you have a lead writing a large check, you want a clean cap table and a real valuation, or stacked SAFEs are getting hard to model.
Watch the stacking trap: several uncapped or high-cap SAFEs feel painless until they all convert at the Series A and reveal you sold more than you thought. Always model the fully-converted table before signing the next one. Practitioner red lines: keep cumulative SAFE dilution before the priced round under roughly 20-25%; if the stack is heading past that, or a single round would sell more than ~25%, it is time to price the round instead of adding another SAFE.
Worked example: the stack that ate 31%
A founder raises three post-money SAFEs over 18 months, each feeling small:
- $500k on a $5M post-money cap → 10.0%
- $750k on a $7.5M cap → 10.0%
- $1M on a $9M cap → 11.1%
No shares have moved, so the cap table still "looks" clean. But 31.1% of the company is already spoken for. At the Series A the lead takes 20% and requires a 10% option pool - carved out pre-money, so it also comes from the founders. Fully converted, the founders wake up below 45% before the B, having believed they were "only giving up 10% at a time."
The fix, applied in time: after the second SAFE (20% committed), the correct move was to price the third raise. A $1M-plus check with 20% already stacked is exactly the "stacked SAFEs are getting hard to model" trigger above - and a priced round would have set the pool with the investors sharing the dilution conversation openly, instead of it landing silently on the founders.
Anti-patterns
- Raising on a cap so low it craters your ownership at conversion.
- Treating SAFE money as non-dilutive because no shares moved yet.
- Stacking SAFEs without modeling combined conversion - especially past the ~20-25% cumulative line.
- A convertible note whose maturity hits before your next round.
Quality bar
- Every SAFE in the stack is converted in the model - none treated as "not real dilution yet."
- The fully-converted table includes the next round's option pool, carved where the term sheet actually carves it.
- Both cap and discount conversion are modeled, with the investor taking the better of the two.
- The recommendation names specific terms to seek and resist, not just an instrument.
- Founder ownership after the modeled priced round is stated as a single number.
Deliverable
A recommendation (SAFE / note / priced) with the reasoning for this stage, the specific terms to seek and to resist (cap, discount, MFN), and a fully-converted dilution model for the chosen path. Carry terms into [[term-sheet-negotiation]].
