LinkedIn co-founder played key role in Microsoft OpenAI ties, baggage included

Reid Hoffman’s exit from Microsoft’s board closes a direct line between one of the company’s most influential directors and the AI network that helped shape its partnership with OpenAI. Hoffman, the LinkedIn co-founder, told Microsoft he would not stand for reelection and will remain on the board only until the company’s annual shareholder meeting at the end of the year. He has served since 2017, after Microsoft bought LinkedIn for $27 billion in 2016.

The governance significance runs deeper than a routine board change. Hoffman was an early OpenAI donor when the startup launched in 2015 as a nonprofit, and he sat on OpenAI’s board until 2023, when he stepped away as Microsoft’s investments and technology partnership with OpenAI intensified. Hoffman said at the time that leaving would help avoid “downstream potential issues” for OpenAI and for Greylock portfolio companies he had backed, a signal that the overlap had become a conflict-management problem rather than a simple advisory role.

Hoffman’s influence in the AI ecosystem extended beyond OpenAI. He co-founded Inflection AI with Mustafa Suleyman in 2022, and Microsoft later hired Suleyman and several other Inflection employees in 2024. Suleyman now leads Microsoft AI, the unit working on generative models, which shows how closely Hoffman’s network intersected with Microsoft’s own AI strategy. Hoffman has now said he needs to get back to “founder mode” as he focuses on Manas, his AI-native biopharmaceutical company.

That influence came with baggage. Earlier this year, Justice Department documents showed communications between Hoffman and Jeffrey Epstein, and Hoffman apologized for associating with him. Hoffman has also long been a donor to Democratic campaigns. Microsoft said his decision was not the result of any disagreement over policy or operations, but his departure still strips the board of a director who sat at the intersection of Microsoft, OpenAI, Inflection and the broader venture network now under intense scrutiny.
