E2B

Sandboxed runtime infrastructure for AI agents

E2B provides the runtime infrastructure AI agents execute in, building what it describes as the next hyperscaler for agents. Its customers include Microsoft, Perplexity, Hugging Face, Manus and Groq — companies whose agents need to run generated code somewhere isolated, which is a hard infrastructure problem rather than a model one. Founded in 2023, the company has raised over $37 million and scaled from $1 million to eight-figure ARR in under a year, and is now preparing for its next stage of growth.
