Due diligence is the systematic process of investigating and verifying all material facts about a potential investment before committing capital, typically conducted by angel investors and venture capitalists to assess risk and validate the opportunity. This investigation spans financial records, legal documents, market conditions, team capabilities, and operational processes to uncover red flags and confirm that the startup's claims align with reality.
Why It Matters
Proper due diligence separates successful angel investors from those who lose capital on avoidable mistakes. Statistics show that 70% of startup failures stem from issues that thorough investigation could have identified—unrealistic market assumptions, weak unit economics, or problematic cap tables. For investors, spending 40-80 hours on due diligence for a $50,000 investment can prevent total loss and identify negotiation leverage points that improve deal terms. The process also builds your understanding of the business, enabling you to provide more valuable guidance post-investment.
Example
An angel investor considers investing $100,000 in a SaaS company claiming $50,000 in monthly recurring revenue. During financial due diligence, she requests bank statements and customer contracts, discovering that $30,000 of that revenue comes from a single enterprise client on a trial basis set to expire in 60 days. Legal due diligence reveals the founders never formalized their equity split, creating potential conflict. Technical due diligence by a hired expert shows the codebase relies heavily on a single developer with no documentation. Rather than walking away entirely, the investor uses these findings to negotiate a lower valuation, require the trial client to convert to an annual contract before closing, and mandate that founders execute a proper vesting agreement. The investment proceeds at $2.5 million pre-money instead of the original $4 million ask.
Related Terms
Key related concepts include Term Sheet, the preliminary agreement outlining investment conditions that triggers the due diligence period, and Cap Table, the ownership structure document that requires careful examination during legal due diligence. Understanding Data Room is also essential, as this is where startups organize documents for investor review during the due diligence process.
