Here's my guess, but would love to see what people think:
- Seed Round - Y Combinator (Mar 22, 2012). - Seed Round (Oct 7, 2016): Raised $600K. - Seed Round (May 22, 2017): Raised $3.2M. - Series A (Feb 19, 2019): Raised $11M. - Series B (Nov 26, 2019): Raised $30M. - Series B (May 28, 2020): Raised $28.8M at a pre-money valuation of $321.3M. - Series C (May 20, 2021): Raised $130M at a pre-money valuation of $1.4B.
My rough guess of the dilution is 93% -> 78% -> 66% -> 53% -> 42% -> 39% -> 35%. I tried taking into account option pools and standard dilution.
Assuming all investors had 1X liquidation rights participating, then they get the $203.6M invested back, and the founders split the 35% of the $771M which comes out to about $90M per founder (3 co-founders). After CA tax (assuming 48.5% take-home) that's ~$44M.
I found this nice blog explaining founder dilution: https://dri.es/founder-dilution#4
LMK where I went wrong in my calculation.
