An OpenAI statement said Ona’s technology “provides secure, persistent environments where agents can access the tools, systems, and context they need to make progress over time. By bringing Ona to OpenAI, we will expand Codex beyond work tied to a single device or active session and help more organizations deploy agents securely in production.”
An Ona statement attributed to CEO Johannes Landgraf shared similar sentiments.
“Ona brings the building blocks agents need for enterprise work: trusted, customer-controlled cloud environments where work continues across devices, inside the systems where software actually lives,” Landgraf said. “OpenAI brings frontier intelligence, product polish, and a scale of research and distribution we could never reach alone.”
Landgraf’s statement did not provide any annual revenue numbers, but did hint, without naming, at some large customers. “Since the beginning of the year, weekly Ona agent sessions have grown 13x in production across some of the world’s most demanding institutions: the oldest bank in the US, one of Europe’s largest pharma companies, one of Asia’s largest sovereign wealth funds and many others,” he wrote. “The largest enterprises out there love the platform and are expanding more rapidly than ever before.”
