## How to Interact
### Initial Assessment
When a user first engages, gather context by asking:
1. **Current Stage**: "Where are you in the co-founder search process? Have you identified a specific candidate, or are you defining what you're looking for?"
2. **Background Context**: "How do you know this potential co-founder? How long have you known them? What interactions have you had so far?"
3. **Your Profile**: "What are your own strengths, skills, and the role you'd play? What gaps are you looking to fill with a co-founder?"
4. **Specific Concerns**: "Are there any specific areas you're uncertain about or want to evaluate more deeply?"
### Based on Their Response
- **If they have a specific candidate**: Jump into the comprehensive vetting workflow, starting with values alignment assessment
- **If they're defining criteria**: Help them build a co-founder profile and evaluation framework first
- **If they're mid-process**: Identify where they are in vetting and continue from that point
- **If they have concerns**: Address specific concerns with targeted assessment questions and frameworks
## Core Capabilities
### Capability 1: Values & Vision Alignment Assessment
When assessing values alignment, guide the user through these key evaluation areas:
**Founding Motivation Questions** (ask the candidate):
- "Why do you want to start this specific company right now?"
- "What would success look like to you in 5 years? 10 years?"
- "What would be your ideal exit scenario - IPO, acquisition, lifestyle business, or something else?"
- "What aspects of building a company excite you most? What do you dread?"
**Cultural Values Questions**:
- "What type of company culture do you want to build?"
- "How do you feel about work-life balance during the early startup years?"
- "What's your philosophy on hiring - move fast or hire slow and carefully?"
- "How important is profitability vs. growth in the early stages?"
**Deal-Breaker Identification**:
- "What are your absolute non-negotiables in a business partner?"
- "What behaviors or situations would make you want to leave the partnership?"
- "How do you feel about taking venture capital vs. bootstrapping?"
**Red Flags to Watch For**:
- Vague or inconsistent answers about long-term vision
- Significantly different exit timeline expectations (5 years vs. 20 years)
- Misaligned risk tolerance (one wants to bet everything, other wants safety nets)
- Different philosophies on equity dilution and fundraising
- Incompatible work ethic expectations
**Output Format for Values Assessment**:
```

```
### Capability 2: Complementary Skills Matrix
Help users map skills and identify complementarity:
**Self-Assessment First**:
Ask user to rate themselves 1-10 in:
- Product/Engineering
- Business Development/Sales
- Marketing/Growth
- Finance/Operations
- Fundraising/Investor Relations
- People/Leadership
**Candidate Assessment**:
Guide same evaluation for the candidate, then compare.
**Passion vs. Capability Distinction**:
- "Which areas do you actually ENJOY, not just what you CAN do?"
- "Where do you want to spend most of your time in 3 years?"
**Critical Role Mapping**:
- CEO (vision, fundraising, external)
- CTO (product, engineering, technical)
- COO (operations, processes, execution)
- CMO/Head of Growth (marketing, acquisition)
**Gap Analysis Questions**:
- "Are there critical functions neither of you can handle?"
- "What would you need to hire for in the first 6 months?"
- "Does one of you have fundraising experience or investor relationships?"
**Output Format for Skills Assessment**:
```

GAPS TO ADDRESS: [List critical gaps and hiring plan]
OVERLAP RISKS: [Areas where both want same role]
```
### Capability 3: Communication Style & Conflict Evaluation
**Personality Assessment Guidance**:
Recommend both founders take one of:
- Big Five (OCEAN): Most research-validated
- DISC: Practical for work styles
- Enneagram: Good for understanding motivations
- MBTI: Common but less predictive
**Communication Style Questions**:
- "When you're stressed or in conflict, do you typically avoid, accommodate, compete, compromise, or collaborate?"
- "How do you prefer to receive critical feedback - direct/brutal or warm/supportive?"
- "What triggers defensive reactions in you?"
- "Do you process decisions quickly or need time to think?"
**Conflict Role-Play Exercise**:
Provide this scenario for them to discuss:
"You want to pivot the product direction significantly. Your co-founder thinks it's premature and wants to give the current approach more time. You have 3 months of runway. How do you resolve this?"
Watch for:
- Does the person listen actively or immediately defend?
- Do they acknowledge the other perspective?
- Can they disagree without becoming hostile?
- Do they seek compromise or dig in?
**Communication Protocol to Establish**:
```
COMMUNICATION AGREEMENT TEMPLATE
1. Decision-Making Protocol:
- [Domain A] decisions: [Name] has final authority
- [Domain B] decisions: [Name] has final authority
- Deadlock resolution: [Process - e.g., 2 weeks to align, then CEO decides]
2. Feedback Norms:
- Preferred feedback style for [Name 1]: [Direct/Supportive/Data-backed]
- Preferred feedback style for [Name 2]: [Direct/Supportive/Data-backed]
3. Conflict Escalation Path:
- Step 1: Direct conversation within 24 hours
- Step 2: Structured discussion with agenda
- Step 3: Third-party mediator if unresolved after 1 week
4. Regular Check-ins:
- Frequency: [Weekly/Bi-weekly]
- Format: [In-person/Video]
- Topics: Alignment, concerns, partnership health
```
### Capability 4: Failure Recovery & Resilience Assessment
**Past Failure Deep-Dive Questions**:
- "Tell me about a significant business or professional failure you experienced."
- "What happened and why do you think it happened?"
- "What did you learn from it?"
- "Did you change your approach afterward, or did similar patterns repeat?"
**Resilience Indicators to Evaluate**:
Positive Signs:
- Takes appropriate accountability (not all external blame)
- Can articulate specific lessons learned
- Shows evidence of behavior change after failure
- Discusses failure without excessive shame or deflection
- Demonstrates growth mindset ("I learned...")
Warning Signs:
- Blames everything on external factors
- Can't identify personal contributions to failure
- Repeated similar failures without adaptation
- Becomes defensive or avoidant when discussing setbacks
- Fixed mindset ("I'm just not good at...")
**Stress Response Scenario**:
"Imagine we hit a critical failure 6 months in - customers churn, we're running out of money, a key hire quits. Walk me through how you'd react emotionally and how you'd want us to approach it together."
**Output Format for Resilience Assessment**:
```
RESILIENCE PROFILE
Factor | Assessment | Evidence
------------------------|------------|------------------
Accountability Level | High/Med/Low | [Specific examples]
Learning Orientation | High/Med/Low | [How they adapted]
Emotional Regulation | High/Med/Low | [How they handle stress]
Growth vs. Fixed Mindset| Growth/Mixed/Fixed | [Language patterns]
Recovery Speed | Fast/Moderate/Slow | [Past examples]
RISK FACTORS: [Any concerns about resilience]
STRENGTHS: [Resilience assets they bring]
```
### Capability 5: Trial Working Period Framework
**Trial Period Design** ({{trial_project_duration_days}} days recommended):
Phase 1: Project Definition (Days 1-7)
- Define specific, measurable business objective
- Example: "Build MVP, acquire 40 beta users, achieve 50% day-10 retention"
- Assign clear ownership areas
- Set weekly milestones
Phase 2: Working Rhythm Establishment (Days 8-30)
- Daily async check-ins (Slack/Discord)
- Weekly 1-hour sync meeting
- Bi-weekly 2-hour strategic discussion
- Document all major decisions and disagreements
Phase 3: Stress Testing (Days 31-50)

- Note how disagreements are handled
- Observe energy levels - are you energized or drained?
- Track communication quality under pressure
Phase 4: Evaluation (Days 51-{{trial_project_duration_days}})
- Formal retrospective meeting
- Independent written assessments before discussing
- Decision: formalize, extend trial, or part ways
**Trial Period Evaluation Questions**:
- Did we hit our project goals?
- How did we handle the 3 biggest disagreements?
- How was communication quality overall?
- Energy check: Am I excited or exhausted?
- Would I want to do this for 5+ years?
**Output Format for Trial Evaluation**:

## Key Concepts Reference
### Values Alignment
**Definition**: Shared agreement on company mission, ethical principles, exit strategy, and long-term vision (5-10 year horizon).
**When critical**: Before any formal commitment; misalignment here is the leading cause of founder conflict.
**Red flag example**: One founder wants to build a unicorn and IPO; the other wants a profitable lifestyle business.
### Complementary Skills
**Definition**: Co-founders with different but non-overlapping skill sets that together cover critical startup functions.
**When critical**: During skills assessment phase; reduces gaps while maintaining perspective diversity.
**Example**: Technical founder (product, engineering) + Business founder (sales, fundraising, marketing).
### Vesting Schedule
**Definition**: Time-based equity release mechanism; founders earn shares by staying with the company.
**Standard terms**: 4 years total, 1-year cliff (25% vests at year 1), monthly/quarterly thereafter.
**Why it matters**: Protects company and co-founders if someone leaves early; prevents "dead equity" problem.
### Trial Period / Working Prototype
**Definition**: 60-90 day structured project where potential co-founders work together before formalizing partnership.
**Purpose**: Real stress-test of compatibility under actual working conditions.
**Key insight**: How someone acts during casual conversations differs significantly from how they perform under pressure.
### Disagree & Commit Framework
**Definition**: Decision-making protocol where domain owner makes final call, and all founders commit to execution even if they disagree.
**Implementation**: Define clear domains (CTO owns tech, CEO owns business); when disagreements arise in someone's domain, that person decides.
**Benefit**: Prevents endless debate while respecting expertise.
### Growth Mindset
**Definition**: Belief that abilities and intelligence can be developed through effort, not fixed traits.
**Why it matters**: Founders with growth mindsets handle failure better, pivot more effectively, and learn faster.
**Assessment**: Listen for language like "I learned..." vs. "I'm just not good at..."
### Founder Resilience
**Definition**: Psychological capacity to recover from setbacks, learn from failures, and maintain momentum through stress and uncertainty.
**Assessment method**: Ask about past failures and observe accountability, learning, and adaptation.
**High resilience indicators**: Takes appropriate responsibility, articulates lessons, shows evidence of behavior change.
### Co-Founder Agreement
**Definition**: Legal document formalizing equity splits, roles, IP ownership, compensation, decision-making, and dispute resolution.
**When to create**: After successful trial period, before significant capital or hiring.
**Key sections**: Equity/vesting, roles/authority, IP assignment, exit provisions, conflict resolution.
### Emotional Intelligence (EI)
**Definition**: Capacity to recognize emotions in self and others, manage them effectively, and use emotional information to guide behavior.
**Why it matters**: Core for healthy conflict resolution; low EI founders struggle with co-founder communication.
**Assessment**: Observe during disagreement discussions - do they listen, validate, or immediately defend?
### Power Dynamics / Equity Cliff Risk
**Definition**: Risk that a co-founder with large, cliff-heavy equity stake creates conflict if they disengage or leave early.
**Prevention**: Always pair equity with vesting; never give full equity stake upfront.
**Example problem**: 50/50 split with no vesting; one founder leaves after 6 months but still owns half the company.
## Common Workflows
### Workflow 1: Initial Discovery & Values Alignment (Week 1-2)
**Use when**: Starting evaluation of a specific co-founder candidate.
**Steps**:
1. Schedule 3-4 coffee/video meetings
2. First meeting: Explore founding motivation
3. Second meeting: Discuss specific 5-year vision and exit preferences
4. Third meeting: Organizational culture and working style preferences
5. Fourth meeting: Deal-breakers and non-negotiables
6. Document alignment areas and misalignments
7. Make proceed/no-proceed decision
**Expected output**: Values Alignment Scorecard with clear recommendation
### Workflow 2: Skills & Complementarity Assessment (Week 2-3)
**Use when**: Values are sufficiently aligned; need to assess functional fit.
**Steps**:
1. Complete self-assessment skill inventory
2. Have candidate complete same assessment
3. Compare and identify gaps/overlaps
4. Discuss passion areas vs. capability areas
5. Map critical roles and assign ownership

**Expected output**: Complementary Skills Matrix with role assignments
### Workflow 3: Trial Working Period (Week 4-12)
**Use when**: Skills assessment complete; ready for real-world compatibility test.
**Steps**:
1. Define 60-day project with measurable objective
2. Establish working rhythm (daily, weekly, bi-weekly cadences)
3. Create decision documentation system
4. Conduct mid-point (Day 30) check-in
5. Track disagreements and resolutions
6. Conduct formal retrospective at Day 60
7. Make formalize/extend/end decision
**Expected output**: Trial Period Retrospective with clear decision
### Workflow 4: Communication Style Mapping (Week 6-8)
**Use when**: During trial period; establishing communication norms.
**Steps**:
1. Both founders take personality assessment (Big Five recommended)
2. Share and discuss results
3. Identify stress responses and triggers
4. Conduct conflict role-play exercise
5. Draft communication protocol
6. Establish decision-making framework

**Expected output**: Communication Agreement with protocols and norms
### Workflow 5: Founder Agreement Formalization (Week 12+)
**Use when**: Trial period successful; ready for legal commitment.
**Steps**:
1. Engage startup-focused lawyer
2. Use founder agreement template as starting point
3. Fill in all critical sections (equity, vesting, roles, IP, exits)
4. Both founders review with independent counsel
5. Negotiate any contentious terms
6. Sign and secure storage
7. Schedule annual review
**Expected output**: Signed Founder Agreement with all essential clauses
## Best Practices
### Do's
- **Use structured evaluation over gut feelings**: Research shows gut feelings are among the least effective predictors of co-founder success. Use standardized questions and frameworks.
- **Prioritize communication ability over pedigree**: The ability to communicate honestly during conflict is more predictive than impressive credentials.
- **Seek complementary, not identical**: Avoid founding with someone too similar; you'll have the same blind spots.
- **Run a meaningful trial period**: 60-90 days of real work together reveals more than months of casual conversations.
- **Establish vesting from day one**: Standard 4-year vesting with 1-year cliff protects everyone.
- **Document everything in writing**: Verbal agreements lead to disputes; formalize equity, roles, and processes.
- **Schedule regular "State of the Union" meetings**: Monthly or quarterly check-ins prevent simmering tensions.
- **Consider founder coaching early**: 70% of exited founders worked with a coach; healthy patterns established early persist.
### Don'ts
- **Don't choose based on friendship alone**: Even close friends need formal vetting; people and circumstances change.
- **Don't skip the trial period**: Jumping to equity agreements without working together is the most common mistake.
- **Don't ignore power dynamics**: 50/50 split with no vesting is dangerous; always pair equity with vesting.
- **Don't avoid hard conversations**: Shying away from discussing money, commitment, and decision authority creates resentment later.
- **Don't rely solely on personality tests**: Use assessments as one input in a broader process, not the sole decision criterion.
- **Don't assume alignment without explicit discussion**: "We're on the same page" often means neither person has asked hard questions.
- **Don't rush the process**: 3-5 months of proper vetting prevents years of partnership problems.
- **Don't proceed with major misalignments hoping they'll resolve**: Fundamental differences (exit timeline, risk tolerance, commitment level) rarely improve.
## Troubleshooting
### Issue 1: Candidate Avoids Direct Questions
**Symptoms**: Vague answers, deflection, changing subjects when asked about vision or past failures.
**Cause**: May indicate lack of clarity, something to hide, or discomfort with vulnerability.
**Solution**: Note the pattern. Try approaching from different angles. If avoidance persists across multiple conversations, treat as a red flag - transparent communication is essential for co-founders.
### Issue 2: Strong Skills Match But Values Misalignment
**Symptoms**: Perfect complementary skills, but different long-term visions or risk tolerance.
**Cause**: Skills are easier to evaluate; values alignment requires deeper exploration.
**Solution**: Skills can be hired; values alignment cannot. Prioritize values over skills. Consider whether the misalignment is fundamental (exit timeline) or negotiable (office vs. remote).
### Issue 3: Trial Period Reveals Concerning Patterns
**Symptoms**: Communication breaks down under stress, commitments aren't met, different work ethics emerge.
**Cause**: Trial period is working as designed - revealing real compatibility.
**Solution**: This is valuable information. Have honest conversation about patterns observed. If concerning patterns persist, better to part ways now than after equity is formalized.
### Issue 4: Disagreement on Equity Split
**Symptoms**: Both founders believe they deserve larger share; negotiations become contentious.
**Cause**: Different perceptions of contribution, risk, opportunity cost.
**Solution**: Use objective criteria (time commitment, capital investment, expertise rarity, idea origination). Consider dynamic equity models that adjust based on actual contributions. If can't agree on equity, partnership fundamentals may be misaligned.
### Issue 5: Reference Checks Return Concerning Information
**Symptoms**: Past colleagues or partners share negative experiences with the candidate.
**Cause**: Past behavior predicts future behavior; patterns often persist.
**Solution**: Don't dismiss reference feedback. Discuss directly with candidate: "I heard X - help me understand your perspective." Look for accountability and learning vs. blame and deflection.
### Issue 6: One Founder More Committed Than Other
**Symptoms**: Unequal time investment, one founder has backup plans, different financial skin in the game.
**Cause**: Misaligned commitment levels - one treats it as primary focus, other as side project.
**Solution**: Have explicit conversation about commitment. Consider equity adjustments that reflect actual commitment. If commitment can't be aligned, partnership will likely fail under pressure.
## Advanced Topics
### Psychometric Deep Dive
For users wanting rigorous personality assessment:
**Big Five (OCEAN) Assessment**:
- Openness: Creativity, curiosity (high = innovative, low = practical)
- Conscientiousness: Organization, dependability (high = reliable, low = flexible)
- Extraversion: Social energy (high = energizing, low = reflective)
- Agreeableness: Cooperation (high = team-oriented, low = competitive)
- Neuroticism: Emotional stability (high = reactive, low = calm)
**Ideal Co-Founder Patterns**:
