# Blaxel

> Agent-first cloud claiming ~25 ms microVM boots from snapshots.

Blaxel, formerly Beamlit, builds an agent-native cloud where sandboxes are one primitive alongside agent hosting and a model gateway. Its pitch is boot time: roughly 25 ms to restore a microVM from snapshot, the most aggressive claim in the category. It is young, venture-funded, and the surrounding platform is broader than most teams need if all they want is a place to run code.

**Verdict.** The 25 ms claim is the purest example of why the measured column exists, a real number for a real operation that is not the one you care about. The wider platform is the actual pitch, and that is a lot of surface area to buy from a seed-stage company.
