Picking a co-founder is the single highest-variance decision you'll make.
FounderFit gives you evidence — scenario-based, rubric-scored, reviewer-approved — before the equity split.
Three steps between resume and equity split.
Build the assessment
Pick a role, drop in the real problem you're facing next quarter, or pull from our curated scenario bank. AI can also generate scenarios tailored to your stage and domain.
Candidate solves it
Candidates get a distraction-free, writer-grade experience. One scenario at a time. Autosave. Soft time cues instead of stressful timers. We capture structured-thinking signals silently.
AI scores, you review
AI scores every answer against a role-specific rubric with direct evidence. Your reviewer sees the AI draft side-by-side with the raw answer — and has the last word.
A different lens for every founding seat.
Built with operators who've founded, hired, and fired at this level. Each rubric weights competencies by what actually moves the outcome.
Chief Executive Officer
Sets direction, raises capital, recruits leadership, and owns the company's outcome.
Chief Technology Officer
Owns architecture, engineering hiring, technical strategy, and long-term technical risk.
The right co-founder decision is a rubric, not a gut feel.
