Microsoft has announced that LinkedIn co-founder Reid Hoffman will step down from its board of directors, bringing to a close a nearly ten-year tenure that followed one of Silicon Valley’s most consequential corporate deals.

The company said Hoffman, 58, notified the board on Tuesday that he would not stand for re-election. He will remain in place until Microsoft’s annual shareholder meeting at the end of the year.

In a regulatory filing, Microsoft confirmed the transition, marking the end of a period in which Hoffman helped guide the company through its aggressive push into cloud computing, enterprise software expansion, and—more recently—artificial intelligence partnerships.

From LinkedIn Founder to Microsoft Director

Hoffman is best known as the co-founder of LinkedIn, which he launched in 2002 and grew into the dominant professional networking platform used by recruiters and job seekers worldwide.

That trajectory culminated in 2016 when Microsoft acquired LinkedIn for $27 billion, one of the company’s largest acquisitions at the time. Hoffman joined Microsoft’s board shortly afterward in 2017, becoming a key Silicon Valley voice inside the software giant’s leadership structure.

His presence on the board also symbolised Microsoft’s deeper integration with the tech startup ecosystem, particularly as the company repositioned itself around cloud infrastructure and AI.

Deep Ties to the AI Boom — and OpenAI

Hoffman has long been a central figure in the artificial intelligence ecosystem.

He was an early donor to OpenAI when it launched in 2015 as a nonprofit research lab, before stepping down from its board in 2023 amid Microsoft’s increasingly close partnership with the organisation.

At the time, Hoffman said: “By stepping off the board, I can proactively put to rest any downstream potential issues for both OpenAI and all Greylock portfolio companies I’ve backed.”

Microsoft has since become OpenAI’s most important commercial partner, investing heavily and integrating its models across products such as Copilot.

Hoffman also co-founded AI startup Inflection alongside Mustafa Suleyman, a DeepMind co-founder later acquired into Microsoft’s AI leadership structure. Suleyman now serves as CEO of Microsoft AI, overseeing the company’s generative AI development efforts.

“Founder Mode” and a Shift Toward New Ventures

Hoffman’s decision to leave Microsoft’s board appears to reflect a broader shift back toward startup-building.

He is currently co-founder of Manas, which describes itself as an “AI-native biopharmaceutical company” working at the intersection of artificial intelligence and drug discovery.

Speaking in a podcast conversation with Microsoft CEO Satya Nadella released Friday, Hoffman said: “At the end of the year, I should really be transitioning right now to being in founder mode.”

The remark underscores a familiar pattern for Hoffman, who has moved repeatedly between entrepreneurship, venture capital, and corporate governance roles over the past two decades.

Before LinkedIn, he was an executive at PayPal, part of the influential “PayPal Mafia” cohort that helped shape much of modern Silicon Valley.

He later became a general partner at venture capital firm Greylock in 2009, backing numerous startups across the tech sector.

Controversies and Public Scrutiny

Hoffman’s departure also comes amid renewed public scrutiny.

Earlier this year, U.S. Justice Department documents revealed communications between Hoffman and convicted sex offender Jeffrey Epstein, who died in jail in 2019. Hoffman later apologised for his association with Epstein.

He has also faced political controversy. Reports that the Justice Department was investigating a group linked to Hoffman over donations tied to E. Jean Carroll’s legal battles against former U.S. President Donald Trump drew further attention. Hoffman denied wrongdoing, stating on X: “He is investigating me because I supported E Jean’s lawsuit — where a jury found Trump liable for sexually assaulting her, and a court of appeals upheld the decision.”

A Silicon Valley Figure Exiting Corporate Governance

Hoffman’s exit marks the end of a long chapter connecting one of Silicon Valley’s most influential venture capitalists to Microsoft’s boardroom.

While he steps away from formal governance, his footprint remains deeply embedded across the AI landscape—from OpenAI’s early formation to the leadership reshaping Microsoft’s artificial intelligence strategy today.

His departure signals a return to startup-building, even as the companies he helped shape continue to define the industry’s next phase.
