Matt Clifford Joins Anthropic After Shaping UK AI Policy

Matt Clifford, who designed the UK government's AI strategy, has joined Anthropic as managing director for international affairs, according to The Guardian. The move comes roughly a year after he stepped down from his unpaid advisory role under Prime Minister Keir Starmer.

In his new position, Clifford will oversee Anthropic's relationships with governments across the UK, Europe, Asia-Pacific, and India. The 41-year-old tech investor and co-founder of venture capital firm Entrepreneurs First will retain his chairmanship of Aria, the UK's Advanced Research and Invention Agency, though he will recuse himself from matters involving Anthropic.

Why it matters

Clifford's transition highlights an accelerating pattern of senior UK officials moving to major AI companies shortly after leaving government roles. As AI regulation takes shape globally, the flow of policy architects into the private sector raises questions about whether companies gain unfair advantages through insider knowledge—and whether former advisers prioritize corporate interests over public ones when engaging their former colleagues.

Growing concerns over the revolving door

The appointment has drawn criticism from transparency advocates and lawmakers who see it as part of a troubling trend. Tom Brake, chief executive of campaign group Unlock Democracy, told The Guardian that taking extensive government knowledge about sensitive AI policy to a private company "gives that company a huge advantage."

Clifford joins a roster of prominent UK political figures who have moved to Silicon Valley firms. Former Deputy Prime Minister Nick Clegg joined Meta in 2018, while former Prime Minister Rishi Sunak took advisory roles at both Microsoft and Anthropic last year. Former Chancellor George Osborne also joined OpenAI.

Chi Onwurah, Labour chair of the science, innovation and technology committee, acknowledged Clifford's contributions to UK AI policy but expressed concern about the timing. "I hope he will use his skills and experience to promote responsible AI to Anthropic rather than promoting irresponsible AI to the UK government," she said, as reported by The Guardian.

Clifford's government legacy

Before joining Starmer's administration, Clifford served as Sunak's representative to the 2023 AI Safety Summit and helped establish what became the AI Security Institute. He drafted the current government's AI action plan, which promotes AI growth zones for datacentres and development of UK-owned AI models.

Clifford defended the move by emphasizing collaboration between sectors. "Countries everywhere want real agency over how this technology is built and used, and my job is to make Anthropic a genuine partner in that," he said.

An Anthropic spokesperson told The Guardian that the UK represents "one of dozens" of governments the company engages with, noting that hiring people who understand government operations is essential across all markets.

Anthropic, developer of the Claude chatbot, is reportedly preparing for a public offering that could value the company at $2 trillion. The company said Clifford's expertise will help navigate complex regulatory environments as AI governance frameworks evolve worldwide.
