Due Diligence

Also called: DD, Diligence

TL;DR

The investigation an investor performs to verify the claims in the pitch and assess all material risks before signing a term sheet or wiring funds.

Due diligence covers commercial diligence (market, customers, competition), financial diligence (financials, cap table, projections), legal diligence (contracts, IP, employment), technical diligence (architecture, security), and reference diligence (founders, customers, employees). At early stages, diligence is light and fast; at growth stages it can take 6 to 8 weeks and involve multiple external advisors.

Founders often underestimate how much friction late-discovered surprises (unfiled IP assignments, undisclosed prior commitments) introduce. Pre-empting diligence with a clean data room and proactive disclosure is the cheapest insurance available.

Worked example

Series B diligence over 3 weeks: 8 customer reference calls, 4 ex-employee calls, P&L QoE by an outside accountant ($45k cost), cohort-retention rebuild, code review by an ex-CTO advisor, market sizing rebuild, compete pings to 3 competitors. ~120 founder-hours for 3 weeks.

Common pitfalls

•Hiding problems and being caught in diligence.
•Underestimating how long diligence takes at later stages.
•Failing to brief the team and customer references before they're contacted.
