# About E2B

> E2B provides AI agents with secure, on-demand machines and real-world tools. The company is building the cloud layer between an agent's models and the work it performs.

## Why E2B exists

Traditional containers, Kubernetes clusters, and virtual machines were designed to run software defined ahead of time. Agents generate code and choose actions at runtime, so they need a different execution environment: isolated from the host, fast enough for interactive products, stateful when work takes time, and equipped with the same kinds of tools a person uses on a computer.

E2B gives every agent session a Firecracker microVM with its own kernel. The sandbox exposes shell, filesystem, network, storage, desktop, lifecycle, and observability capabilities through an API.

## Company

E2B was founded in 2023 by Vasek Mlejnsky and Tomas Valenta. Its legal name is FoundryLabs, Inc., and the team operates from San Francisco and Prague.

The project began when the founders connected an agent to sandbox technology from their earlier developer-tool work. They shifted their focus from the agent itself to the reusable machine underneath it and released the first E2B SDK in 2023.

## Milestones

- The Python SDK launched in 2023, followed by JavaScript, Code Interpreter, and Desktop products.
- E2B SDK 1.0 shipped in 2024.
- Desktop Sandbox added a graphical Linux environment for computer-use agents in 2024.
- E2B announced a $21 million Series A in 2025.
- E2B passed one billion sandbox starts in 2026.
- E2B reports that 94 of the Fortune 100 have signed up.
- More than 100,000 teams have run at least one sandbox on E2B.

## Direction

E2B is building infrastructure that adapts to an agent's workload while remaining independent of the model and orchestration framework. The sandbox is the place where an agent's code, tools, files, data connections, and actions come together. Teams can use E2B Cloud, place the data plane in their own cloud, or operate the open-source runtime.
