Seed Startups Showing Engineering Acceleration

Seed-stage startups, typically post-angel/accelerator, pre-Series A. Engineering signals here often correlate with the first production build-out and the earliest customer-facing launches. Currently tracking 87 seed startups across 15 sectors. liberusoftware leads with 135 commits over 14 days (+3275%).

How fast are seed startups shipping in Q3 2026?

We rank 87 seed startups by GitHub engineering acceleration for Q3 2026. liberusoftware tops the list at 135 commits per 14-day window (+3275%), against a cohort average of 32commits. The most common breakout pattern this period is “Deceleration”. Rankings refresh weekly and every number links back to a public GitHub source.

Commit velocityis the number of commits a startup’s public repositories receive over a rolling 14-day window, used here as a proxy for engineering throughput. A rising velocity paired with contributor growth is the earliest public signal that a seed team is scaling ahead of a fundraise.

Investor insight

Seed-stage acceleration is the sweet spot for scouts and solo GPs. Deploy-frequency spikes and infrastructure buildouts at this stage usually precede the Series A announcement by 6-12 weeks. The window to get in before the round is competitive is narrow but real.
