OpenAI Acquires Ona to Enhance Codex with Secure Cloud Infrastructure

OpenAI has announced the acquisition of Ona, a company specializing in secure cloud execution and orchestration technology, on June 11, 2026. This strategic move integrates Ona’s technology into OpenAI’s Codex platform, enabling AI agents to operate persistently within customer-controlled cloud environments. The acquisition details, including financial terms, remain undisclosed.

Codex, OpenAI’s AI-powered coding assistant, currently serves over 5 million users weekly, marking a 400% increase in usage since early 2026. Initially designed for software developers, Codex now supports a broader range of complex workflows, from research and analysis to automation across various knowledge work domains.

As Codex evolves, its most impactful applications involve tasks that extend over hours or days rather than minutes. OpenAI emphasizes the need for AI agents to continue working beyond the initial user session, allowing users to monitor progress, provide input, and review outcomes remotely. Ona’s technology facilitates this by providing secure, persistent cloud environments where agents can access necessary tools, systems, and contextual data over time.

Ona has a track record of enabling over 2 million developers to transition software development from local machines to secure, reproducible cloud environments. Its customer-controlled execution model allows organizations to maintain strict governance over where AI agents run, what resources they access, and how credentials and activities are managed. This aligns with enterprise requirements for security, compliance, and operational control.

Johannes Landgraf, Co-Founder and CEO of Ona, stated, “Agents need more than intelligence; they need a trusted workspace. We built Ona to give agents cloud environments with the context, control and collaboration enterprises require. Joining OpenAI lets us bring that foundation into Codex, helping organizations deploy agents with confidence and giving humans more agency over their work.” Thibault Sottiaux, Core Products Lead at OpenAI, added, “Enterprises want powerful agents that can do real work while meeting the security and control requirements of their environments. Ona will help us make Codex easier to deploy securely across production workflows for customers operating at the highest standards of trust and scale.”

The acquisition supports OpenAI’s goal to scale Codex across production workflows by combining advanced AI models with secure, persistent execution environments. This integration is expected to reduce infrastructure costs, streamline deployment processes, and broaden Codex’s applicability beyond software development to include complex, long-duration enterprise workflows.

Industry trends show increasing demand for AI agents capable of sustained, autonomous operation within secure cloud infrastructures. OpenAI’s acquisition of Ona positions it to strengthen its leadership in AI-assisted software development and automation, while competitors may accelerate efforts to develop similar persistent AI agent capabilities.

Financial specifics of the deal were not disclosed. The acquisition is subject to customary closing conditions, including regulatory approvals. Until completion, OpenAI and Ona will operate independently. Post-closing, Ona’s team will integrate with OpenAI’s Codex group to advance secure enterprise execution capabilities and expand Codex’s reach to more organizations globally.

Looking ahead, OpenAI aims to enable engineering teams to safely manage sustained work across the software lifecycle, including testing, issue resolution, application modernization, vulnerability management, and complex workflow support. The integration of Ona’s technology is a critical step toward delivering secure, scalable AI agent deployments that meet enterprise security and governance standards.
