How to Source Pre-Seed Startups Before Anyone Else

Pre-seed sourcing is the hardest and highest-ROI activity in venture. Get in early and you see the best deals at the lowest valuations. But pre-seed companies have no press, no funding history, and often no public traction.

The best pre-seed signal is engineering output. Teams shipping meaningful code weekly are teams worth meeting. GitDealFlow tracks this across 400+ venture-backed startups and surfaces pre-seed breakouts weekly.

Supplement GitDealFlow with: Product Hunt launches (consumer products), Hacker News Show HN posts (developer tools), Y Combinator batches (accelerator alumni), and Twitter/X founder threads.

For each prospect, research the founder (LinkedIn, previous companies), the market (CB Insights market maps), and the engineering velocity (GitDealFlow signal page). Reach out with a specific, personalized note.

FAQ

What's the best pre-seed sourcing channel?

Personal network remains #1. GitDealFlow is the best tool for surfacing pre-seed companies you don't know yet. Hacker News Show HN is excellent for developer tools.

How do I evaluate a pre-seed startup?

Founder-market fit (do they know the problem deeply?), engineering velocity (GitDealFlow), and the size of the problem. Pre-seed is about team and trajectory, not traction.

How early should I reach out to founders?

As early as possible. Most pre-seed founders appreciate early interest. Use GitDealFlow to catch teams within weeks of starting — before they're raising.
