San Francisco-based firm E2B, which provides a secure, open-source cloud platform for running AI-generated code and agentic workflows at scale, has secured a $21 million Series A funding round, bringing its total funding to $32 million.
- Founded in 2023 by Vasek Mlejnsky and Tomas Valenta, E2B develops a secure, open-source cloud platform that allows AI agents to execute code and run complex workflows at scale.
- The company provides sandboxed environments, virtual machines that start in under 200 milliseconds, where AI-generated code can be executed safely, without compromising enterprise security or stability.
- E2B’s core product is built to meet the infrastructure demands of production-grade AI agents. It enables agents to perform multi-step tasks by offering real-world computing tools, isolation via microVMs (powered by Firecracker), persistent storage, and integration with enterprise systems. The platform is LLM-agnostic and supports any programming language or AI framework
- Companies can deploy E2B in their cloud or on-premise, and use it to scale agentic systems, automate code execution, conduct research, and train models. The firm’s infrastructure is already in use by 88% of the Fortune 100 and has powered hundreds of millions of sandbox sessions to date.
Details of the deal
- E2B’s $21 million Series A funding round was led by Insight Partners, with participation from Decibel, Sunflower Capital, Kaya VC, and angel investor Scott Johnston, former CEO of Docker.
- E2B will use the $21 million Series A funding to expand its engineering, product, and go-to-market teams based in San Francisco. The capital will accelerate the development of its sandbox platform to enhance secure, scalable infrastructure for AI agents.
- Additionally, the funding will support meeting the increasing global demand for the platform, allowing E2B to improve its cloud environments, add new modular features such as credential management and monitoring tools, and solidify its position as the enterprise standard for production-grade agentic workflows.
"With E2B, we are laying the groundwork for that future now, one sandbox at a time. We’re grateful to have incredible investors like Insight Partners on this journey with us, and we’re more motivated than ever to deliver on our promise: giving AI agents the cloud machines they need to think and to act, " E2B's founders, commented in a statement.
