Microsoft absorbs Inflection's team without buying the company

Microsoft announced that Mustafa Suleyman, co-founder of both DeepMind and Inflection AI, was joining the company as executive vice president and chief executive of a new unit, Microsoft AI, reporting directly to Satya Nadella. Inflection co-founder and chief scientist Karén Simonyan joined alongside him, along with most of Inflection’s roughly 70-person staff. The new division absorbed Microsoft’s existing Copilot, Bing, Edge and generative-AI consumer teams.

Microsoft did not acquire Inflection. Reporting attributed to Bloomberg, which broke the deal’s terms, put the total value at around $650 million: roughly $620 million as a non-exclusive licence fee for Inflection’s models, including Inflection-2.5, for use on Microsoft Azure, and about $30 million paid to Inflection in exchange for waiving legal claims related to the hiring of its staff. Inflection itself continued to exist as a nominally independent company, using the licensing payment to return capital to investors including Greylock and Dragoneer, reportedly at a modest premium to what they had put in, while pivoting toward enterprise AI under new leadership.

The structure — hire the people, licence the technology, leave the corporate shell standing — drew immediate comparison to an acquisition without the regulatory review one would typically trigger, and UK and EU competition authorities did examine the deal; the UK’s Competition and Markets Authority ultimately declined to pursue an in-depth investigation. Inflection was one of the best-funded AI start-ups to have failed to find a durable independent path, having raised over a billion dollars to build the consumer chatbot Pi. The deal became the reference case for the “reverse acquihire” pattern — talent and IP absorbed via licensing and hiring rather than a share purchase — that recurred later in 2024 and 2025 with Character.AI, Scale AI and Windsurf.
