Blaxel is the perpetual sandbox platform for AI agents that need to run code fast. We let you keep infinite, secure code sandboxes on automatic standby while co-hosting your agents for near instant latency. This is enabled by our own technical backbone: a 25ms cold-start serverless compute engine.

Now processing billions of requests, we power the coding agents and background AIs for top AI startups & scaleups like Webflow or HumanBehavior. We solve the agentic infrastructure problems that traditional clouds aren’t built for, such has running AI code securely, statefully and with ultra-low latency — so that AI companies can focus on building generational products.

We raised a $7.3M seed round, led by First Round Capital.
