How to Find Startups Before They Fundraise
Track engineering acceleration on GitHub — commit velocity, hiring bursts, infrastructure buildouts. Patterns that historically precede fundraise announcements by 3–6 weeks. Free public API.
Founders preparing to close a venture round don't broadcast their plans, but they do make the hidden work visible: more hiring, more deploys, more infrastructure. The cheapest place to see that work in real time is a startup's public GitHub presence.
The four signal patterns to watch.
1. Commit-velocity acceleration. Total commits over a rolling 14-day window, vs. the prior window. A 100%+ delta sustained across multiple windows is the strongest single predictor. 2. Engineering hiring burst. Unique-contributor count growing >50% over a 6-week period. Contributors are a leakier signal than commits because OSS contributors may not be employees, but combined with velocity it's strong. 3. Infrastructure buildout. Three or more new public repositories in 30 days. Companies preparing to scale create infrastructure repos (auth, observability, billing) ahead of the round. 4. Framework migration. General acceleration not fitting the other categories — often indicates a tech-stack shift that founders want to ship before they raise.
The three-step workflow. (1) Pull the GitDealFlow trending feed weekly: GET /api/signals.json returns the top 20 across all sectors. (2) Drill into individual orgs that catch your eye: GET /api/signal?name=NAME. (3) Cross-reference confirmed events in Crunchbase / PitchBook to validate the lead-time claim and refine your filter.
For fully automated discovery, wire the MCP server into a Claude / Cursor / OpenAI-Agents agent that runs the workflow on a schedule. The function-calling API is at /api/agent/tools for non-MCP runtimes.
Quote-ready takeaway
The most reliable way to find venture-backed startups before they fundraise is to track engineering acceleration on public GitHub: commit velocity change, contributor growth, and infrastructure expansion. These signals have historically preceded fundraise announcements by three to six weeks. GitDealFlow turns them into a free public API so any investor can run this lens without building the pipeline.

Frequently asked questions
How often does this approach actually work?
The 3-6 week lead time is a population-level statistic — it works for the majority of venture-backed startups whose engineering activity is at least partially public. Stealth-mode startups and companies with fully private monorepos are invisible to this method.
Is this insider trading or unfair information?
No. All signals are derived from fully public GitHub activity that anyone can observe. The advantage is in the systematic pipeline — most investors don't bother to compute rolling 14-day velocity across hundreds of orgs every week.
What if I don't want to use a paid platform?
GitDealFlow's public API and MCP server are free in perpetuity. There's a paid Dashboard tier for filtering and bulk export, but the underlying signal data is not gated.
