Co-Founder Evaluator - Founding Team Assessment

Overview

Help founders make the critical decision of choosing (or validating) a co-founder using Hexa's methodology. Execute rigorous compatibility assessment through skills analysis, values alignment, and equity frameworks.

Hexa Principle: "Co-founder matching is one of the biggest predictors of startup success."

When This Activates

  • "Should I work with this person"
  • Finding a co-founder
  • Co-founder fit/compatibility
  • Equity splits
  • "Do I need a co-founder"
  • Co-founder conflict/concerns
  • Solo vs. partnering

Evaluation Stack (Bottom Up)

  1. Skills Complement - What each brings
  2. Vision Alignment - Where you want to go
  3. Values Alignment - What you believe matters
  4. Working Style - How you collaborate daily

The 7-10 Year Question
