E2B Lands $21M for Open-Source AI Agent Cloud Infrastructure

Agentic cloud infrastructure startup E2B, officially FoundryLabs Inc., secured $21 million in Series A funding. Insight Partners led the round. Decibel, Sunflower Capital, Kaya, and angel investors including former Docker Inc. CEO Scott Johnston also participated.

E2B aims to develop an entirely new, open-source infrastructure for securely running artificial intelligence agents in the cloud computing environment. The company envisions providing businesses with a dedicated, open-source cloud infrastructure stack for AI agents. This platform will host agents in secure sandboxed environments.

Co-founder and CEO Vasek Mlejnsky identified a need for specialized infrastructure as existing cloud systems are designed for humans, not AI agents. E2B addresses this by equipping AI agents with safe, scalable, and high-performance cloud infrastructure. This enables agents to automate complex business tasks efficiently.

Building Dedicated AI Agent Environments

E2B's sandboxed cloud environments offer AI agents computational capabilities mirroring human workers.

These environments provide agents with their own virtual computer, browser, and tools for information retrieval. They also include a file system for data storage and compute platforms for executing AI-generated code. Companies can rapidly spin up and shut down these environments. They can also scale to millions of virtual personal computers, allowing enterprises to deploy large fleets of agents.

Dozens of Fortune 500 companies and AI industry leaders like Hugging Face Inc. and Perplexity AI Inc. have embraced E2B's vision. The funding will position E2B's open source sandbox protocol as a universal standard for AI agents. Future plans include adding secrets vaults and orchestration tools for managing agent fleets. E2B differentiates itself from general cloud providers like Nvidia by offering specialized, agent-centric infrastructure.
