Founded to solve a fundamental challenge in deploying AI coding agents — safely executing arbitrary, AI-generated code in isolated environments without the latency, security risks, or infrastructure complexity of traditional virtualization — E2B built a sandbox API that spins up ephemeral, containerized execution environments in milliseconds.\n\nE2B's sandbox API enables AI coding agents, automated testing pipelines, and developer tools to run code in fully isolated environments with configurable compute resources, file system access, and internet connectivity. Each sandbox is disposable, eliminating state contamination between agent runs, and the millisecond cold-start performance is critical for AI agent loops where dozens of code execution steps may occur per task. The platform supports Python, JavaScript, and other major languages with pre-configured AI development environments that include common ML libraries and tools.\n\nE2B has achieved remarkable enterprise penetration, with its infrastructure used by 88% of the Fortune 100 — a statistic that speaks to both the ubiquity of AI coding tools in large enterprises and E2B's position as the default sandboxing layer. The company raised $21M in a Series A led by Insight Partners in July 2025, with hundreds of millions of sandbox sessions running monthly on its platform. As AI coding agents move from developer experiments to mission-critical enterprise workflows, E2B's secure execution infrastructure becomes an increasingly essential component of the production AI stack. ## Frequently Asked Questions ### What does E2B do? E2B provides secure, sandboxed cloud environments where AI agents can safely execute code, enabling enterprises to deploy autonomous AI workflows without security risks. ### Who uses E2B? 88% of Fortune 100 companies use E2B, along with Perplexity for data analysis, Groq for secure code execution, and Lindy for custom Python/JS workflows. ### How much has E2B raised? E2B raised $21M in Series A funding in July 2025 led by Insight Partners, bringing total funding to $35M. ### What is E2B and what does it provide for AI developers? E2B (short for 'e-to-b' or 'edge to browser') provides secure cloud sandboxes for running AI-generated code. Developers building AI coding agents or LLM-powered applications use E2B to execute untrusted code safely in isolated environments, preventing security risks while enabling their AI systems to run, test, and iterate on code autonomously. ### What programming languages and environments does E2B support? E2B supports Python, JavaScript/TypeScript, and other popular languages within its sandbox environments. Sandboxes can be customized with specific packages, libraries, and runtime configurations, allowing developers to match the execution environment to their application's requirements. ### How does E2B handle security for code execution? E2B uses isolated microVM-based sandboxes that prevent code from accessing the host system or other customers' environments. Each execution runs in an ephemeral container with strict resource limits and network controls, making it safe to run arbitrary AI-generated code at scale without risking system compromise. ### What is E2B's pricing model? E2B offers usage-based pricing based on compute time consumed by sandbox executions. A free tier is available for developers to prototype and test, with paid plans providing higher concurrency limits, longer execution windows, and dedicated compute resources for production workloads. ### How does E2B integrate with popular AI frameworks? E2B offers SDKs and integrations for popular AI development frameworks including LangChain, LlamaIndex, and direct API access compatible with OpenAI-style function calling patterns. This makes it straightforward to add code execution capabilities to existing AI agents without rebuilding infrastructure from scratch. ## Tags ai-powered, b2b, infrastructure, saas --- *Data from geo.sig.ai Brand Intelligence Database.
