Mustafa Suleyman-founded Inflection AI to return to London
Silicon Valley startup Inflection AI is marking a return to London as the company forges ahead with its expansion plans, CityAM can reveal.
The artificial intelligence business was launched in 2022 by Deepmind co-founder Mustafa Suleyman and attracted early backing from Linkedin founder Reid Hoffman. It released its own large language model, Pi, and was valued at $4bn in a June 2023 funding round.
But in 2024, Suleyman left the business after being poached to run Microsoft’s AI division, along with most of Inflection’s staff. Its UK corporate entity was shuttered shortly thereafter.
Inflection has since pivoted to offering enterprise AI systems and has quietly rebuilt its workforce, doubling its headcount to around 80 staff over the past 18 months, according to data from LinkedIn.
The company has now set up a UK subsidiary with a central London address as it expands operations beyond the US.
An Inflection AI spokesperson said: “We are excited to re-establish our presence in the UK.
“We previously had a UK entity that closed in early 2025, and we are now establishing a new entity as we look to expand our talented team with more exceptional engineers.”
The company declined to comment on how many staff it planned to recruit in London.
London becomes Europe’s AI capital
The move adds Inflection to a host of US AI firms that have set up operations in London, of which the majority are based near to Google Deepmind’s headquarters in Kings Cross.
Last month, ChatGPT maker OpenAI unveiled plans to open its first permanent London office in the district, while Warren Street-based Anthropic said it would open an office with enough space for 800 staff.
Tech and AI firms have leaded over 1m square feet of office space in London since the start of last year, according to data compiled by Knight Frank.
Britain’s AI sector pulled in a record £8.3bn of investment last year, as global investors raced to back the country’s next generation of AI firms, with London tightening its grip as Europe’s leading tech hub.
Research from Barclays Eagle Labs found funding into UK AI companies surged in 2025 after a sluggish period for venture capital markets, driven by growing demand for businesses building everything from AI infrastructure to legal software.
