SAFEs vs Priced Rounds: What You Are Really Signing

A SAFE looks like the simple option. No valuation argument, no board seat, five pages instead of eighty, money in the bank in a fortnight. That simplicity is real, but it is bought by deferring the dilution question rather than answering it — and founders who never do the conversion maths are routinely surprised at the priced round.

What each instrument actually is

A SAFE (Simple Agreement for Future Equity) is a right to shares later. It is not a loan, has no interest and no maturity date. It converts when a qualifying priced round happens.

A convertible note is the same idea wrapped in debt: it accrues interest, usually 4-8%, and has a maturity date at which, in theory, it must be repaid. In practice maturity is almost always extended, but the date gives the investor leverage.

A priced round sells preferred stock at an agreed price per share today. The valuation is settled, the cap table updates immediately, and the documents include liquidation preferences, protective provisions and often a board seat.

| | SAFE | Convertible note | Priced round | | --- | --- | --- | --- | | Valuation set now | No | No | Yes | | Interest / maturity | No | Yes | No | | Legal cost | $2k-$5k | $3k-$8k | $25k-$60k | | Time to close | 1-3 weeks | 2-4 weeks | 6-12 weeks | | Board seat | Rare | Rare | Common | | Dilution visible today | No | No | Yes |

The two numbers on a SAFE

The valuation cap is the maximum valuation at which your money converts. A $500,000 SAFE with an $8M cap converts as though the company were worth $8M, even if the priced round happens at $30M.

The discount is a percentage off the priced round price, typically 15-20%. When a SAFE has both a cap and a discount, the investor gets whichever is better for them.

Worked example. You raise $500,000 on an $8M post-money cap. Eighteen months later you raise a Series A at a $32M pre-money valuation.

| | Calculation | Result | | --- | --- | --- | | Conversion at cap | $500,000 / $8,000,000 | 6.25% of the company | | Conversion at 20% discount only | $500,000 / ($32M x 0.8) | 1.95% | | Investor takes | Better of the two | 6.25% |

That is the entire point of the cap, and it is fair — the investor took the early risk. What founders miss is what happens when several of those exist at once.

The stacking problem

Because SAFEs are invisible on the cap table until they convert, founders raise them serially and track each one in isolation.

Suppose you raise, over two years:

| Instrument | Amount | Post-money cap | Converted ownership | | --- | --- | --- | --- | | SAFE 1 | $250,000 | $5M | 5.0% | | SAFE 2 | $500,000 | $8M | 6.25% | | SAFE 3 | $750,000 | $12M | 6.25% | | Total | $1.5M | | 17.5% |

Add a Series A selling 20% and a 10% option pool refresh, and the founders have given away roughly 48% of the company before the Series A money is even spent. Every single one of those conversations felt small at the time.

Post-money vs pre-money caps matter here. The modern post-money SAFE fixes the investor's percentage — meaning every subsequent SAFE you raise dilutes the founders, not the earlier SAFE holders. Pre-money SAFEs shared that dilution. The post-money version is friendlier to investors and clearer to model, but it puts the whole cost of stacking on you.

When each is the right choice

Use a SAFE when:

• You are raising under roughly $1.5M in total
• There is no clear lead setting terms
• You expect a meaningful valuation step-up within 18 months
• Speed genuinely matters more than certainty

Use a priced round when:

• You are raising $2M or more
• A lead investor wants a board seat and governance
• Your existing SAFE stack is already large enough to be confusing
• You want the dilution settled and visible

Rules that keep the stack safe

1. Model conversion before every new instrument. Maintain a spreadsheet showing fully diluted ownership assuming all SAFEs convert at their caps plus your next round plus a 10% pool. If that number scares you, stop raising on SAFEs.
2. Keep the caps consistent with progress. Raising a second SAFE at the same cap as the first tells later investors nothing improved.
3. Never let the total SAFE amount exceed roughly 20-25% of your target post-money. Above that, you are running a priced round without the documents.
4. Include the pool in the model. Investors price the round assuming a new option pool that comes out of the pre-money — your side of the table.

Common mistakes

• Treating a high cap as a win. A cap far above what the next round will support means the SAFE converts at the discount instead, and it anchors the next negotiation awkwardly.
• Assuming a note's maturity date is decorative. It is leverage, and at a bad moment the holder can use it.
• Raising "just a bit more" four times. The fourth SAFE is where the founders quietly lose control of the cap table.
• Forgetting MFN clauses. A most-favoured-nation clause gives an earlier investor the best terms you subsequently grant anyone. Grant it sparingly.

How the simulator models it

Garage to IPO negotiates every round against your actual traction, and the ownership you hold entering a round determines how much the next one costs you. Raising early and often at low valuations shows up exactly as it does in life — a founder who reached the IPO stage with a thin remaining stake because each individual raise looked reasonable in isolation.
