Founders obsess over fractional equity points while their revenue sits at zero. Stop staring at spreadsheets and use these standard dilution benchmarks to map your raises so you can get back to building. Here is the reality check on how much of your company you actually keep.
Follow these stages to understand how your ownership stake shrinks over time. Each step builds on the last, showing the compounding effect of dilution.
1.
Incorporation and founder splitYou split the pie among founders before anyone else writes a check. Keep it simple and use vesting schedules so no one walks away with free equity.
Sample math: Founders start with 100% (e.g., two founders at 50% each).
2.
Pre-seed roundYou raise initial capital via SAFEs or convertible notes to build the MVP. Standard
Y Combinator SAFE terms dictate how these eventually convert into equity.
Sample math: Investors take 10-15% of the company. Founders drop to 85-90%.
3.
Seed roundYou price the round and officially convert those early SAFEs. You will also carve out an initial employee equity pool, which comes directly out of the pre-raise cap table. Data from industry reports, like those from
Carta, shows median seed dilution hovering around 20%. You can model this using a standard
cap table template.
Sample math: Seed investors purchase 15-25% equity. The option pool takes 10-15%. Founder ownership drops to 55-65%.
4.
Series A roundYou find product-market fit and raise institutional venture capital to scale. The lead investor will likely demand a refresh of the employee option pool to ensure enough equity is available for key hires.
Sample math: Series A investors require 20-25% equity. The option pool is refreshed by 5-10%. Founder ownership compresses to 35-45%.
- Pre-seed dilution (SAFE/note): 10-15%
- Seed round dilution (priced): 15-25%
- Series A round dilution (priced): 20-25%
- Initial employee option pool: 10-15%
- Series A option pool refresh: 5-10%
Sample math: If your company is valued at a $4M pre-money valuation and you raise a $1M seed round, your post-money valuation becomes $5M. The new investors own $1M of the $5M total, or 20% of the company. All existing shareholders (founders, previous investors) are diluted proportionally by this 20%.
