Founder Equity Split Decision Engine
Build a SaaS tool that helps founders determine fair equity splits when one party contributes capital and another contributes expertise, relationships, or execution. The product would model ownership, vesting, dilution, liquidation preference, and contribution weightings to produce defensible scenarios founders can review before involving counsel.
Why this matters
You are about to start a company and the most important early decision is already contentious: how much of the business should go to the person who is critical to execution but not writing the check. Advice from peers ranges from token equity to near-equal ownership, and every answer seems to depend on vague ideas like loyalty, risk, and hustle. You do not want to insult a key partner, but you also cannot ignore the capital you are putting at risk. Spreadsheets and blog posts do not help because they fail to connect economics, governance, and founder expectations in one place. You need a tool that turns a messy emotional negotiation into a structured, explainable decision.
- · Built for Repeat founders, small business acquirers launching new ventures, and first-time startup teams negotiating founder ownership where roles and capital contributions are unequal..
- · Most likely monetization: SaaS subscription.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Founders may treat equity decisions as relationship-driven and ignore software recommendations when emotions or ego dominate.
- 2Existing free content and advisor opinions may be perceived as good enough for a one-time decision.
- 3Without strong credibility signals, users may hesitate to trust a new product for ownership decisions worth millions.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion showed sustained confusion over whether the person in question should be treated as an employee or a co-founder, with many commenters arguing the role classification changes everything. Roughly a dozen comments focused on fair ownership ranges, and the suggested numbers varied dramatically. Several participants also tried to separate founder effort from invested capital, indicating strong demand for structured scenario modeling rather than generic rules of thumb.
