About CofounderFit
We're on a mission to reduce startup failure rates by helping founders test their cofounder compatibility before they commit.
The Problem
65% of startups fail due to cofounder conflict. Yet founders typically spend more time choosing their laptop than evaluating compatibility with the person they'll be "married" to for the next 5-10 years.
Most cofounder breakups happen not because of lack of skills, but because of fundamental misalignments in:
- Leadership style and decision-making
- Risk tolerance and growth ambitions
- Communication preferences and conflict resolution
- Core values and work-life priorities
By the time these misalignments surface, founders have already split equity, raised money, and built a team. Untangling a cofounder relationship at that stage is messy, expensive, and often fatal to the company.
Our Solution
CofounderFit is a psychometric assessment platform that predicts cofounder compatibility before you commit. Think of it as a "pre-nup for startups."
Our proprietary 58-question assessment evaluates 8 key dimensions that matter most for cofounder relationships:
Unlike generic personality tests (MBTI, Big Five), CofounderFit is specifically designed for the unique challenges of cofounder relationships. Our algorithm identifies:
- Alignment areas: Where you naturally work well together
- Complementary differences: Where your differences create strength
- Tension zones: Where conflicts are likely to arise
- Red flags: Deal-breaking misalignments that predict failure
