What Is Due Diligence?
Due diligence is the structured investigation investors run before wiring money. Its job is to confirm that the story told in the pitch deck survives contact with reality: that revenue is real and recurring, that the IP is owned, that the cap table is clean, that the product works, and that the market is as big as claimed. It is the difference between investing in a narrative and investing in a company.
For early-stage rounds the process is compressed, a seed due diligence often takes two to four weeks rather than months, but the scope is the same. Investors who skip it are making a bet on trust alone, and in a market where the best deals are sourced early, the discipline is what separates professionals from gamblers.
What Due Diligence Covers
- Financial: revenue quality, burn rate, unit economics, runway, and whether the numbers match the narrative.
- Legal: incorporation, IP ownership, contracts, employee agreements, and cap table accuracy.
- Technical: architecture, security posture, codebase health, and engineering velocity, can this team ship what they promise?
- Market: total addressable market, competition, go-to-market motion, and pricing evidence.
- Team: backgrounds, references, past outcomes, and whether the team can recruit the next tier of talent.
Why It Matters to Early-Stage Investors
At the seed stage there is little public data, so diligence is largely primary research: calls with customers, code reviews, reference checks, and founder conversations. The investors who do this well build an information advantage that compounds, they see problems before they become public, and they see momentum before it becomes a priced round. Technical due diligence in particular is underweighted by most angels, which is exactly why objective engineering data is valuable.
GitDealFlow's Role in Due Diligence
GitDealFlow's engineering momentum data provides the objective signal layer for technical diligence. Commit velocity, contributor growth, and repository expansion, tracked across 350+ startups from public GitHub activity, show whether a team is actually accelerating, plateauing, or quietly winding down. The methodology is published on SSRN under CC BY 4.0 with an open dataset, so the numbers can be verified rather than taken on faith. In a diligence process built on interviews and PDFs, that verifiable layer is the difference-maker.
Frequently Asked Questions
What is covered in DD?
Financial: revenue, burn, unit economics. Legal: IP, contracts, cap table. Technical: product, architecture, engineering velocity (GitDealFlow). Market: TAM, competition, GTM. Team: background, references, culture.
How long does DD take?
2-6 weeks. Pre-seed: 1-2 weeks. Seed: 3-4 weeks. Series A+: 4-8 weeks. GitDealFlow's engineering data accelerates technical DD.
Who conducts due diligence in an angel round?
The lead investor typically coordinates it, with specialists handling legal and financial reviews. Angels who join the round can run their own lightweight checks, and increasingly, independent engineering data checks.
What usually kills a deal in DD?
The most common deal-killers are undisclosed liabilities, messy cap tables, IP that isn't owned by the company, and a wide gap between the pitch and the underlying metrics, including stalled engineering output.
