E2B, the open-source secure sandbox runtime for AI agent code execution, reports that 88% of Fortune 100 companies and more than half of Fortune 500 are now on the platform, with hundreds of millions of cloud sandboxes initiated. Sandboxes start in under 200 milliseconds and support any programming language across all major AI models. The company raised $32M total including a $21M Series A led by Insight Partners. E2B is emerging as the default runtime layer in the three-layer agent infrastructure stack: compute (GPU clouds), runtime (E2B sandboxes), and orchestration (Sim Studio, LangGraph).
