How to Use Alternative Data for VC Sourcing — Beyond Crunchbase and PitchBook

The best investors don't just use Crunchbase. They layer GitHub signals, hiring data, web traffic, and product launches into a multi-signal sourcing engine. Here's how.

Step-by-step

Start with GitHub (the fastest signal)

GitHub engineering activity is the earliest signal. Startups start shipping code months before they hire a PR firm or appear on Crunchbase.

Layer on hiring data

Once a startup is shipping, they hire. Track LinkedIn/Wellfound for headcount growth, especially in engineering roles. A startup doubling its engineering team in 6 months is likely raising.

Add web traffic (SimilarWeb/BuiltWith)

Growing web traffic signals product traction. A B2B SaaS startup with accelerating traffic is likely acquiring customers — and likely needs capital to scale.

Watch the product (Product Hunt, changelogs)

Frequent product launches and changelog updates signal a shipping culture. A startup dropping features every 2 weeks and growing is in execution mode.

Cross-reference signals for conviction

One signal is interesting. Three signals converging is conviction. When GitHub + hiring + web traffic all point up, that's a startup worth reaching out to.

Frequently asked questions

Why is alternative data better than traditional sourcing?

Traditional sourcing (Crunchbase, PitchBook) shows you what already happened. Alternative data (GitHub, hiring, web traffic) shows you what's happening right now. The gap is 3-6 weeks — and in hot sectors like AI, that's the difference between getting allocation and getting left out.

Do I need a data team for this?

No — GitDealFlow does the GitHub analysis for you. The other layers (hiring, web traffic) are optional bonuses, not requirements. Start with one strong signal layer and add more over time.
