How this model works

Vesting

New grants vest linearly after the cliff. Existing grants begin with the vested shares you enter, then vest the remainder.

Dilution

Each modeled financing round reduces ownership by the dilution percentage you choose. Rounds are spaced across the time horizon.

The chart interpolates between today's company value and the exit scenario. It is a planning curve, not a forecast.
