Cofounder Question Framework

Cofounder Question Framework

The Hardest Hire You'll Make

**Core Insight:** Bad cofounder < Solo < Good cofounder. Choose wisely.

Solo vs. Cofounder: Decision Framework

✅ Solo Works If You:

• [ ] **Comfortable with sales:** Can close deals yourself
• [ ] **Handle weight alone:** Resilient under pressure
• [ ] **No critical gaps:** Full-stack or can hire fast
• [ ] **Clear on role:** Know exactly what you need to do
• [ ] **Strong network:** Can get advice when stuck

✅ Cofounder Works If You Have:

• [ ] **Complementary skills:** Tech + business, design + eng, etc.
• [ ] **Worked under pressure together:** Startup, big project, crisis
• [ ] **Compatible work styles:** Communication, pace, decision-making
• [ ] **Shared vision:** Aligned on what success looks like
• [ ] **Mutual respect:** Trust their judgment in their domain

⚠️ Bad Cofounder Signs:

• First person who said "yes"
• Met at networking event last month
• "We'll figure it out as we go"
• Unequal commitment (one full-time, one part-time)
• No prior working relationship

**Rule:** 3-month trial before committing. Test the relationship under real pressure.

The 5 Essential Conversations

Have these BEFORE you commit to working together.

Conversation #1: How We Handle Disagreements

Questions to Ask

1. **"Tell me about a time you had a major disagreement at work. What happened?"**

• Listen for: How they resolved it, their role, the outcome

1. **"What if we disagree on a critical decision and can't reach consensus?"**

• Listen for: Process vs. ego, willingness to be wrong

1. **"Who has the final say if we're deadlocked?"**

• Listen for: Clarity on decision authority

Framework: Decision-Making Authority

**Option A: Domain-Based**

Product decisions → CEO/Product cofounder
Technical decisions → CTO
Design decisions → Head of Design
Financial decisions → CEO (after consulting CTO)

**Option B: Majority Vote**

Major decisions → Must agree (raise capital, sell company)
Minor decisions → Owner's call (their domain)
Deadlock → External tiebreaker (advisor, investor)

**Document this.** Write it down. Sign it.

Conversation #2: Equity Split (Day One)

Questions to Ask

1. **"What equity split do you think is fair? Why?"**

• Listen for: Their reasoning, how they value contributions

1. **"What happens if one of us wants to leave in 6 months?"**

• Listen for: Understanding of vesting

1. **"Should we split 50/50 or weighted by role/risk?"**

• Listen for: Ego vs. pragmatism

Framework: How to Split

**Equal (50/50):**

• Both full-time from day 1
• Similar risk (both quit jobs)
• Complementary skills
• Equal commitment

**Weighted:**

• One person came up with idea + built v0.1
• One person full-time, one part-time
• Different financial risk (one has savings, one has mortgage)

**Standard Structure:**

Founder A: ___%
Founder B: ___%
Employee pool: 10-20%
Total: 100%

Vesting: 4 years, 1-year cliff

Red Flags

• **"Let's do 50/50 but I'm only part-time"** → Unfair
• **"I should get more because I had the idea"** → Ideas worth $0
• **"We'll decide later"** → Recipe for disaster

**Document this. Write it down. Sign it. File vesting paperwork.**

Conversation #3: What Does Success Look Like in 5 Years?

Questions to Ask

1. **"Where do you want to be personally in 5 years?"**

• Listen for: Alignment with startup timeline

1. **"What does a successful exit look like to you?"**

• Listen for: $10M vs. $100M vs. IPO expectations

1. **"Would you sell the company for $50M in year 3?"**

• Listen for: Build vs. sell mentality

Framework: Alignment Check

**Misalignment Example:**

Founder A: "I want to build a $1B company and IPO"
Founder B: "I want to sell for $20M in 3 years and retire"

**This will destroy your partnership.**

**Alignment Example:**

Both: "We want to build a lasting company. If we get a great
offer (>$100M) early, we'll consider it. Otherwise, we're in
this for 10+ years."

**Alignment matters more than the specific number.**

Conversation #4: Work Style & Commitment

Questions to Ask

1. **"What energizes you? What drains you?"**

• Listen for: Compatibility of work preferences

1. **"How many hours per week are you willing to commit?"**

• Listen for: Equal commitment

1. **"What's your communication style? (Async vs. sync, meetings vs. docs)"**

• Listen for: Can you work together?

1. **"What are your non-negotiables? (Family time, vacation, hobbies)"**

• Listen for: Realistic expectations

Framework: Work Style Matrix

| **Dimension** | **You** | **Them** | **Compatible?** |

| --- | --- | --- | --- |

| Hours/week | 60 | 60 | ✅ Yes |

| Mornings vs. nights | Early (6am) | Late (10am) | ✅ Yes (overlap) |

| Communication | Async (Slack) | Sync (calls) | ⚠️ Maybe |

| Decision speed | Fast (hours) | Slow (days) | ❌ No |

| Risk tolerance | High | Low | ❌ No |

**Red flags:**

• One full-time, one part-time
• Radically different risk tolerance
• Incompatible communication styles
• Mismatched urgency

**Green flags:**

• Both full-time or both part-time
• Similar urgency and pace
• Overlapping work hours
• Compatible communication preferences

Conversation #5: Reference Checks (Work Under Pressure)

Questions to Ask

1. **"Who have you worked with that I can talk to?"**

• Listen for: Transparency, willingness to share references

1. **"Tell me about a time you were under extreme pressure. How did you handle it?"**

• Listen for: Resilience, problem-solving, honesty about failures

1. **"What will your references say about working with you?"**

• Listen for: Self-awareness

Framework: Reference Questions

**What to ask references:**

1. "How does [name] handle conflict?"
2. "Tell me about a time they failed. What happened?"
3. "Would you work with them again? Why or why not?"
4. "What's their superpower? What's their kryptonite?"
5. "If I'm about to start a company with them, what should I know?"

**Red flags from references:**

• "Difficult to work with"
• "Blames others for failures"
• "Doesn't take feedback well"
• Reference hesitates or is lukewarm

**Green flags:**

• "I'd work with them again in a heartbeat"
• "Best [role] I've worked with"
• "Handles pressure better than anyone"
• Specific examples of their impact

• **Result:** Trust and velocity from day 1

Example 3: Clear Roles

• **Craigslist:** Craig Newmark (solo for years)
