Founder Equity Split Tool
Estimate a practical founder equity split based on time commitment, role criticality, domain contribution and execution ownership across the founding team.
This tool is designed to make early founder conversations more concrete. It is not legal advice and it does not tell you what is fair in moral terms. It simply weights contribution factors into a more disciplined starting point.
