Due Diligence Checklist: What Smart Investors Look for in 2025

Why Diligence Matters More Than Ever

In a market where capital efficiency is paramount, thorough due diligence separates disciplined investors from those who chase hype. Here's a comprehensive checklist organized by category.

Team Assessment

• Founder-market fit: Do the founders have unique insight into this problem?
• Working history: Have the co-founders worked together before?
• Technical depth: Can the team build the product without outsourcing core IP?
• Reference checks: What do former colleagues, employees, and customers say?
• Commitment level: Are all founders full-time and fully vested?

Market Analysis

• Total addressable market: Is this a $1B+ opportunity?
• Growth trajectory: Is the market growing at 15%+ annually?
• Competitive landscape: Who else is solving this and how?
• Timing: What's changed to make this possible now?
• Regulatory risk: Are there pending regulations that could help or hurt?

Product and Technology

• Product-market fit signals: Are users retaining and engaging?
• Technical moat: Is there defensible technology or data advantage?
• Scalability: Can the architecture handle 100x current load?
• IP ownership: Are all IP assignments properly documented?

Financial Health

• Burn rate and runway: How long until they need to raise again?
• Unit economics: Is the path to profitability realistic?
• Revenue quality: Recurring vs. one-time? Concentration risk?
• Cap table cleanliness: Any problematic early investors or unusual terms?

Legal and Compliance

• Corporate structure: Clean incorporation with proper documentation?
• Employment agreements: Non-competes, IP assignments in place?
• Pending litigation: Any current or threatened legal actions?
• Data privacy: GDPR/CCPA compliance if handling user data?

The 48-Hour Rule

After completing diligence, make your investment decision within 48 hours. The longer you deliberate, the more likely you are to talk yourself out of a good deal — or miss the round entirely.
