ONA
A 79-person secure cloud execution vendor acquired by OpenAI to harden the infrastructure behind Codex, whose weekly users grew 400% to over 5 million -- a direct bet on securing agentic AI coding at scale.

Pivoted from Gitpod's cloud dev environments into secure, persistent execution environments purpose-built for autonomous AI coding agents.
79-person team running production cloud development environments prior to the OpenAI acquisition, per independent reporting.
Acquired by OpenAI in June 2026 to secure the infrastructure behind Codex, which grew to over 5 million weekly users, up 400%.
Secure execution sandboxes for AI agents are an emerging must-have as coding agents run longer and more autonomously, though competition is growing fast.
No named enterprise customers of Ona's own platform were disclosed; efficacy evidence is really about Codex's post-acquisition growth, not Ona's standalone traction.
Securely containing autonomous AI agents is becoming one of the most urgent problems in AI security as agentic coding tools scale rapidly.
Why CISOs Should Care
Ona gives organizations deploying AI coding agents a secure, pre-configured cloud execution environment, so agents can access tools, systems, and context without giving them unmanaged direct access to production infrastructure.
What Makes It Different
Ona (formerly Gitpod) built secure, persistent cloud development environments that keep AI coding agents working after the human developer logs off, letting OpenAI's Codex take on longer-running autonomous tasks inside an isolated, controlled execution boundary rather than a developer's own machine.
The Matrix Verdict
60/100 — INCREMENTAL INNOVATOR
A 79-person secure cloud execution vendor acquired by OpenAI to harden the infrastructure behind Codex, whose weekly users grew 400% to over 5 million -- a direct bet on securing agentic AI coding at scale.
Editorial Note: Claims vs. Verified Findings
The '79 person' team size and '5M+ weekly Codex users, up 400%' figures come from OpenAI's and independent outlets' (CNBC, Bloomberg) own acquisition coverage, not from Ona's self-reporting alone.
