Disclosure up front: I built the project this dataset backs, and I am sharing the raw data here because it is genuinely useful for anyone mining founder or engineering signals.
This is Q3 2026 engineering momentum across 350+ startup GitHub organizations in 15 sectors (web3, data infrastructure, enterprise SaaS, robotics, healthcare, legal tech, space tech, and more). Updated weekly.
What is inside, per org: – 14-day commit velocity and velocity change % – contributor count and growth – new-repo creation – a signal label (engineering hiring burst / deploy frequency spike / infrastructure buildout / framework migration) – funding stage estimate (pre-seed through growth) and geography
Collected from public GitHub events only. No private repositories.
The research finding this backs: in a panel of 219 confirmed fundraises (SSRN preprint), a composite of commit velocity and contributor diversity preceded fundraise announcements by 21 to 47 days (median 31), a 3.4x lift over baseline. The methodology page has the full definition; the preprint is at papers.ssrn.com, abstract 6606558.

One caveat worth knowing: velocity-change % saturates at +999% on the biggest jumps, so for top movers rely on the absolute commit counts rather than the percentage.
Happy to answer questions about the pipeline or the caveats.
