Blaxel

An infrastructure platform providing isolated sandboxes that boot in milliseconds and resume in ~25ms with persistent shared memory and programmable networking, solving the problem of ephemeral execution and cold starts for AI agents. It sells to developers and engineering teams building autonomous agents at scale. The platform differentiates by offering persistent environments that stay on standby indefinitely without compute cost, with built-in compute, storage, and networking primitives.
