Buyer analysis

Best fit: Buyers needing secure, isolated runtime infrastructure to execute LLM-generated code or run agents at scale, including as a sandbox layer for RL/agent training.

How we verified this

Confirmed this is the correct company: E2B (e2b.dev), open-source secure cloud sandboxes (Firecracker microVMs) for running AI-generated code and AI agents - matches the directory note. Funding verified against the official Series A blog and multiple press sources: $21M Series A led by Insight Partners (announced 2025-07-28), $11.5M seed led by Decibel, $32M total per the official blog; investors confirmed. HQ San Francisco with a Prague office; founded 2023; OSS Apache-2.0 confirmed via GitHub. Headcount 11-50 / ~37 confirmed via LinkedIn public snippet (a stale '2-10' snippet was disregarded). Downgrades: SOC2 and ISO/HIPAA/GDPR are claimed only on the vendor's JS-rendered trust center and could not be independently verified, so marked claimed-unverified. Revenue downgraded to unknown due to conflicting self-claims (7-figure vs 8-figure/$37M). All customers are vendor self-claimed (homepage/Series A materials); current homepage lists Athena and a '94% of Fortune 100' claim (vs '88%' in the Series A post) - both unverifiable. No valuation disclosed. Overall confidence lowered to medium.
