Q3 2026 · Pre-Seed

Pre-Seed Startups Showing Engineering Acceleration

Earliest-stage technical startups, typically before any institutional round. Engineering activity at this stage is the clearest leading indicator because there is little press, no fundraise announcement, and few public breadcrumbs other than the code itself. Currently tracking 121 pre-seed startups across 15 sectors. untrustedmodders leads with 30 commits over 14 days (+2900%).

How fast are pre-seed startups shipping in Q3 2026?

We rank 121 pre-seed startups by GitHub engineering acceleration for Q3 2026. untrustedmodders tops the list at 30 commits per 14-day window (+2900%), against a cohort average of 47commits. 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 pre-seed team is scaling ahead of a fundraise.

Investor insight

At pre-seed, the GitHub commit graph is often the only public signal of product velocity. Founders are heads-down shipping. A pre-seed startup showing sustained engineering acceleration over a multi-week window is a high-conviction outbound target before the seed round is live.
