Estimate a fair founder equity split using weighted contribution factors. The tool compares capital, time, experience, and execution value to produce an ownership recommendation and fairness score.
The result shows the financing impact on ownership, valuation, conversion, or dilution. A stronger result protects founder ownership while preserving enough incentive for investors and employees.
This estimate is educational and should not replace legal, tax, or fundraising advice. Real term sheets may include preferences, pro rata rights, participation, vesting, and other provisions.
If Founder A contributes 60 points and $20,000 while Founder B contributes 40 points and $10,000, the suggested split leans toward Founder A.
A fair split should reflect future time commitment, role criticality, risk, execution responsibility, capital, IP, and long-term vesting.
Technical founders may receive more if product execution is the main risk, but business founders can justify equal or higher equity when sales, fundraising, or market access is critical.
The best split depends on contribution and future responsibilities. Equal splits can work, but unequal splits may be fairer when roles or risks differ.
Investors generally accept uneven splits when the rationale is clear, documented, and supported by vesting and long-term alignment.
It can be adjusted, but changes after funding can be legally and operationally complex. Vesting and advisor approval are usually safer mechanisms.
