About the Company

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.
