What is due diligence in venture capital?

Due diligence is the investigation a VC firm conducts before investing — reviewing financials, customer references, technology, legal documents, and team backgrounds.

Due diligence (DD) is the process by which a VC firm verifies the claims a startup makes before writing a check. It happens after initial meetings and before final investment approval.

Early-stage due diligence is relatively lightweight. At pre-seed or seed, investors might spend 1-2 weeks doing: - Reference checks on founders (from prior employers, colleagues, investors) - Customer calls (talking to existing customers about the product) - Technical review (if it's a deep-tech company) - Market validation (researching the competitive landscape) - Reviewing financial model and key assumptions

Later-stage due diligence gets more rigorous. At Series B and beyond: - Full financial audit - Legal review (cap table, contracts, IP ownership) - Product/engineering deep dives - Customer cohort analysis - Detailed competitive analysis - Background checks

Data rooms: Companies typically share a virtual data room with key documents — incorporation documents, cap table, financials, customer contracts, key metrics dashboard.

Founder tip: The fastest way to kill a deal in due diligence is inconsistency. If you say X in the pitch and the data shows Y, trust evaporates. Be proactively transparent — investors always find things; it's better to surface issues yourself.
