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)
- Skills Complement - What each brings
- Vision Alignment - Where you want to go
- Values Alignment - What you believe matters
- Working Style - How you collaborate daily
Solo vs. Co-founder
| Favors Solo | Favors Co-founder |
|---|---|
| 80%+ skills covered | Major skill gaps |
| Move fast alone | Need parallel execution |
| Prefer autonomy | Value debate/input |
| Strong network | Need complementary network |
| Bootstrapping | Raising (investors like teams) |
5+ either way: Follow that direction
Skills Matrix
Rate 1-5 for: Technical, Sales, Marketing, Finance/Ops, Leadership, Domain, Fundraising, Recruiting
Ideal: No overlaps >4, no gaps <2

Must pass: Delivered commitments, proactive communication, resolved disagreement, excited to continue
Equity Split Rules
- When in doubt: 50/50
- Always vest (4yr/1yr cliff)
- Get it in writing
| Situation | Split |
|---|---|
| Equal contribution | 50/50 |
| Idea + domain vs. execution | 55/45 - 60/40 |
| Full-time vs. part-time | 60/40 - 70/30 |
Red Flags (Stop)

- Different commitment levels
- Can't resolve disagreements
- Reference concerns
- Gut says no
- Unwilling to vest
