Editable Inputs
Quick Presets:
Base: Seed $15M / A $70M / B $140M post-money, with raises of $5M / $20M / $50M.
Bull: each round’s post-money valuation is 40% higher (Seed $21M → A $98M → B $196M); same raises, less dilution.
Bear: each round’s valuation is 40% lower (Seed $9M → A $42M → B $84M); same raises, more dilution.

Standing Assumptions
Delaware C-corporation issuing 10,000,000 fully-diluted shares at founding.
Five (5) co-founders. Founders 2 through 5 split the non-Founder-1 founder equity equally.
The ungranted ESOP pool of 10% is established at founding and carved from founder equity in this model. In practice, additional ESOP pools are often created at later rounds, diluting cap table members proportionally at the time they are established.
New Hires 1.0 receive 100,000 options between Seed and Series A (drawn from the pool).
New Hires 2.0 receive 250,000 options between Series A and Series B (drawn from the pool).
All stated valuations are POST-MONEY (pre-money = post-money − raise).
Three sequential priced rounds: Seed, Series A, Series B.
No anti-dilution adjustments, liquidation preferences, or convertible-note conversions modeled.
Constraints: each round’s raise cannot exceed 75% of post-money valuation; valuations must be non-decreasing across rounds; Founder 1 founding equity is bounded between 0% and 90%.
