The free Acceleration Watch: five venture-backed teams accelerating on the engineering signal, translated into plain English — 21 to 47 days before the deck circulates. No code-reading, no card.
16 buildable enterprise saas ideas, each with a live-signal join against our GitHub engineering panel. 16 of 16 currently have at least one matching repo showing active commit velocity in Q3 2026.
Each idea is paired against the current-period startup dataset by sector and keyword match. The "repos already trying" join is live — it re-resolves against the latest GitHub signal snapshot on every data refresh, not a one-time snapshot frozen at write time.
The hub groups all ideas by editorial category (AI-Native SaaS, Dev Tools, etc.). This page groups by data sector (Enterprise SaaS) so you can browse ideas mapped to the same GitHub-tracked sector taxonomy used throughout the rest of the site.
