Use GitDealFlow's free startup signal checker to see engineering momentum for any venture-backed startup. See commit velocity, contributor growth, and sector ranking at no cost.
Enter a startup name and get an instant signal report showing how fast the team is shipping, how their velocity compares to sector peers, and whether they're breaking out.
This is the same data top VC firms use internally, now free for angels, founders, and researchers. No signup required for basic lookups.
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 Startup Signal Checker, Check Engineering Momentum: 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.
If Free Startup Signal Checker, Check Engineering Momentum is your entry point, the fastest next steps are fixed: skim the glossary for the three or four terms that anchor the topic, open the research dataset to see the raw weekly snapshots behind the summary numbers, and run one live query against the free momentum checker with a company you already know well. Seeing the signal fire on a familiar name is the quickest way to judge whether code-side sourcing belongs in your own workflow.
One caveat worth stating plainly on Free Startup Signal Checker, Check Engineering Momentum: momentum is a leading indicator, not a verdict. A repository can accelerate for reasons that never become a fundraise, and a quiet quarter does not mean a team is failing. The disciplined use of this page is as one input in a stack, a way to rank where scarce diligence time goes, and a way to notice change early. The methodology page documents every limitation, including the bot filter, the two-period confirmation rule, and the sectors where coverage is thinnest.
