YC X25 — Spring 2025YC X25
The 5 Spring 2025 companies we track, ranked by evidence-graded agent readiness — can an agent actually drive this product? — then built-in AI and PA Score.
This is the YC X25 companies we track, judged on evidence — not a batch-wide census (yet). Coverage grows batch by batch. Scores come from each product’s arena verdicts — see methodology.

A product tracked in more than one arena appears once, in the arena where its PA Score is highest. Unscored means no applicable cells — never zero. Batch stamps verified against YC’s public directory by website domain, never by name.
