OpenAI acquires Ona to bolster Codex with cloud AI-agent platform
OpenAI acquires Ona, integrating the Kiel startup’s cloud AI-agent platform into Codex to enable longer, cross-system coding tasks and support millions of developers.
OpenAI announced on Thursday evening German time that it has acquired Ona, a Kiel-founded startup that built a cloud environment for autonomous AI coding agents, signaling a strategic move to strengthen the company’s Codex offering. The purchase price was not disclosed, but industry sources described the deal as one of the larger exits by a German startup in recent years.
Deal confirmation and undisclosed terms
OpenAI confirmed the acquisition and said Ona will be folded into its Codex product team to accelerate enterprise features and agent orchestration. Company representatives declined to release financial details, and both parties agreed to keep the exact terms confidential.
Industry contacts told reporters the transaction size places the sale among the more significant German startup exits of the past years, reflecting strong strategic value rather than a straightforward financial play. Analysts say the lack of public price information is common in strategic technology buys where integration and talent acquisition are priorities.
Ona’s technology and developer reach
Founded in 2020 as Gitpod in Kiel, Ona pivoted as generative AI advanced, building a cloud workspace designed to host AI agents that can autonomously chain complex development tasks. The platform supplies the contextual knowledge agents need to write code, find bugs, and apply fixes directly within developer environments.
Ona’s team reports that more than two million developers have used the platform, a metric that underlines its traction among software teams seeking to integrate AI agents into real-world workflows. The system’s capacity to maintain context across devices and extended tasks was a key part of its appeal to acquirers.
Strategic fit with OpenAI’s Codex
OpenAI framed the acquisition as a way to bolster Codex, its software-development AI product that the company says reaches more than five million weekly users. Executives described Ona’s agent orchestration and workspace tooling as complementary capabilities that can help Codex tackle longer-running, cross-system coding assignments at enterprise scale.
The deal positions OpenAI to compete more directly with rivals that have invested in code-centric models and integrated development workflows. Integration of Ona’s tooling is expected to enhance Codex’s ability to manage multi-step development pipelines, from design and testing to deployment, without requiring manual context switching.
Market dynamics and valuation gaps
The transaction also highlights valuation and capital gaps between European and American tech markets. European startups, including AI-focused firms, commonly trade at lower revenue multiples than US peers, making them attractive acquisition targets for large American platforms.
Observers note that US buyers often apply revenue multiples in the 20-to-50 range for high-growth software firms, while European valuations tend to cluster in the 10-to-20 range. That difference, combined with comparatively smaller venture capital pools in Europe, has accelerated strategic acquisitions by US companies seeking specialized technology and engineering talent.
Implications for the German and European startup scene
While the acquisition underscores that Germany and Europe can produce enterprise-grade AI tools, it also reignites debate over whether the region can retain and scale such companies independently. Critics argue that limited late-stage capital and lower valuations make exits likely, while proponents say targeted specialisation and proximity to regulated customers create unique European advantages.
Supporters point out that European firms frequently excel where technology must be tightly integrated with complex business processes, compliance regimes, and sector-specific requirements. That proximity to demanding customers can make European startups especially valuable to global AI platforms that need reliable, production-ready solutions.
Founders and investors respond
Ona’s co-founder Johannes Landgraf posted on LinkedIn that he had expected the sale to feel like an ending but instead felt that the company’s work had become “bigger and even more important.” The platform’s early backers, including Speedinvest, which was both the first and largest investor in Ona, described the team’s deep domain knowledge and customer-focused engineering as central to the startup’s appeal.
Florian Obst, a partner at Speedinvest, told reporters that Europe maintains a structural advantage when AI products are developed close to real customer problems, especially in regulated or complex enterprise settings. Such proximity, he argued, is a differentiator that can make specialised European software attractive to major AI providers.
OpenAI’s integration plan will determine how quickly Ona’s tooling appears inside Codex, and whether users of the standalone Ona platform will see immediate changes to access or pricing. Company statements suggest the technology and personnel will be used to accelerate Codex capabilities for enterprise customers.
The acquisition underlines a broader consolidation trend in the AI tooling market, where major model providers are acquiring platform-level capabilities to extend their reach into developer workflows and enterprise systems. This deal will be watched closely as a signal of where competition for code-centric AI is heading and how European startups fit into the global AI ecosystem.
