Understanding SAFEs and Priced Equity Rounds by Kirsty Nathoo
- Core Objective: Founders must actively track dilution and ownership percentages at all lifecycle stages; relying solely on lawyers or assuming a cap table is static is dangerous.
- Primary Instrument: The SAFE (Simple Agreement for Future Equity) is the standard early-stage fundraising tool for US companies, distinguished from convertible debt by the absence of interest rates and maturity dates.
- SAFE Negotiations: Unlike priced rounds with extensive term negotiations, SAFE terms generally boil down to only two variables: the investment amount and the valuation cap.
- Post-Money SAFEs: Y Combinator now mandates post-money SAFEs to simplify dilution calculations, as these clearly show the founder's remaining ownership after all SAFEs convert, unlike pre-money SAFEs.
- Dilution Formula: In a post-money context, an investor's ownership percentage equals their investment amount divided by the post-money valuation cap (e.g., $1M invested / $6M cap = ~16.67% ownership).
- SAFE Conversion Events: A SAFE converts into equity upon three specific triggers: an equity financing round, a liquidity event (sale), or the dissolution of the company.
- SAFE Anatomy: The document consists of five sections, with Sections 1 (event mechanics) and 2 (definitions) being critical for founders to understand to prevent unexpected dilution.
- Incorporation Baseline: In the illustrated example, two founders start with 9.25M shares total, each holding 50% ownership.
- SAFE Round Impact: Raising $200k at a $4M cap (5%) and $800k at an $8M cap (10%) dilutes founders from 100% to 85% ownership, though the official share count on the cap table remains unchanged until conversion.
- Option Pool Creation: Creating an employee stock option pool (ESOP) increases the total share count; in the example, issuing 750k shares from a new pool dilutes founders from 92.5% (of issued shares) to approximately 78.6% (of the total fully diluted capitalization).
- Series A Mechanics: The priced round execution follows a specific three-step sequence: (1) SAFEs convert to shares, (2) the option pool is increased, and (3) new investors invest.
- Cap Table Composition: The "pre-money" price per share calculation in a Series A round includes the shares resulting from SAFE conversions, effectively treating the post-money SAFE conversion shares as part of the pre-money capitalization base.
- Series A Valuation Example: With a $15M pre-money valuation and a $5M raise, the post-money valuation is $20M; the lead investor (investing $4M) acquires 20% ownership, while the full investor group takes 25%.
- Dilution Outcome: By the end of the Series A, founders in the example drop to 51.5% ownership, illustrating the cumulative effect of SAFE dilution, option pool creation, and new equity issuance.
- Convertible Notes: While acceptable (particularly outside the US), combining convertible notes with SAFEs is discouraged as it complicates capitalization calculations; founders are advised to stick to one instrument type.
- Pre- vs. Post-Money Consistency: Companies that raised on pre-money SAFEs can transition to post-money SAFEs for future rounds, though mixing the two requires more complex modeling.
- Optimization Warning: Founders should avoid over-optimizing valuation caps on early SAFEs; in the example, raising $800k at a $10M cap instead of $8M would only increase founder ownership by 1.2 percentage points (52.7% vs. 51.5%) while incurring significant negotiation effort.
- Risk of Over-Dilution: Founders who fail to calculate cumulative SAFE dilution risk ending up with negligible equity (e.g., <10%) post-Seed/Series A, a situation that is difficult to remedy once contracts are signed.
- Forward-Looking Statement: Y Combinator recommends all companies adopt post-money SAFEs going forward to ensure accurate, transparent tracking of founder ownership and dilution.
