GitDealFlow's premise is that engineering activity is a leading indicator, a team ships harder before it raises, and that shows up in public commit history weeks before any announcement. These tools are free, need no signup, and store nothing.
Enter any GitHub organisation or repository and get the GitDealFlow Momentum Score computed live from the public API: commit acceleration against a 12-week baseline, contributor growth, bus factor, repository expansion and a 52-week commit history. It uses the same published formula as the Momentum Index, so a result is directly comparable to the tracked companies there. Your browser calls GitHub directly, nothing is proxied or stored.
Open the momentum checker →Live engineering-activity score for any org or repo, straight from the public GitHub API.

Open →The checklist of signals worth reading on a company before you take the call.
Open →How the score is built, term by term, if you would rather compute it by hand.
Open →First-touch templates for founders you found before anyone announced anything.
Open →A repeatable structure for writing up a company you are looking at.
Open →The weekly sourcing routine, so deal flow is a habit rather than an accident.

This tool is free for the same reason the underlying dataset is public: reproducibility is the product. GitDealFlow tracks engineering momentum across 350+ startup GitHub organizations in 15 sectors, refreshed weekly. The free tools exist so any investor can verify the signal on real data before paying for the pipeline: breakouts surface 21 to 47 days before the round, and the method is published, sourced, and falsifiable rather than a black box.
A practical read-through of Free tools for startup deal flow: the dataset behind this page refreshes weekly across 350+ organizations and 15 sectors, and every figure shown traces to a public GitHub REST API pull. That matters for two reasons. Reproducibility: any number here can be re-derived from primary sources, which is the standard the published methodology sets for itself. Timeliness: engineering acceleration precedes announcements, so this page follows the data cadence rather than the news cycle, and the freshness endpoint always reports the exact pull date.
