UK venture funding surges into AI as investment concentrates in the largest, most proven scale-ups
UK venture funding surged into AI in 2025, with investment increasingly concentrated in the UK’s largest and most proven scaleups, according to NatWest’s inaugural Future of UK Innovation report, published today in partnership with PitchBook.
UK startups raised £17.5bn across more than 2,000 deals last year, even amid a challenging macroeconomic backdrop. The report reveals that investors are placing bigger bets on fewer businesses: rounds over £25m made up more than 70% of the funding – the highest share in a decade – signalling a market where proven business models and demonstrable traction matter more than ever.
NatWest’s research also shows that AI is now one of the defining forces in the UK innovation economy. AI startups raised more than £6bn - over a third of all UK venture capital - helping create five new unicorns and driving some of the strongest exit activity in the market, with a total of 67 exits worth £4bn. This rapid surge in AI activity underscores how decisively capital is shifting toward technologies with clear commercial readiness and global scaling potential.
The report comes ahead of the launch of NatWest Venture Banking, a new offering to support UK’s most ambitious and innovative venture-backed scaleups with tailored financial solutions, strategic expertise and deep ecosystem connectivity. The launch will be marked by a flagship event in April bringing together founders, investors and ecosystem partners.
NatWest has recently set out its commitment to support UK-wide growth, bringing together investment, expertise and partnerships across the real economy under a connected five-point plan: Growing Together. NatWest Venture Banking will focus on companies that have raised institutional investment in target sectors in the innovation economy that are driving the UK’s future growth.
Jenny Edwards, head of NatWest Venture Banking, said: “This report arrives at a defining moment for the UK Innovation Economy. Our venture landscape has proven remarkably resilient, and we are entering a new era of confidence, opportunity and global ambition. At NatWest Venture Banking, our mission is to be the partner of choice for founders, fund managers and investors who believe in the UK’s potential. This report is a call to action—highlighting where value will accrue next, where bottlenecks persist, and where the UK must move decisively to maintain its global leadership.”
David Grunwald, director of Innovation at NatWest Group, said: “Customers and the UK innovation economy benefit most when corporates and startups work together from the very beginning. As funding becomes more selective and efficiency pressures rise, collaborating early and intentionally will help unlock the most value. That’s why we partner and strategically invest in technology start-ups – it helps us spot what will make the biggest difference for our customers whilst bringing those ideas to life faster.
“Heading into 2026, the pace of AI and the rise of globally ambitious UK scaleups make this a pivotal moment – and we’re ready to back the founders building the next generation of companies that will drive UK growth.”
Key trends to watch:
AI is now one of the defining forces in UK innovation
AI startups raised over £6bn in 2025, accounting for more than one third of all UK venture capital, the highest share on record. AI also drove the strongest exit activity, with a total of 67 exits generating £4bn.
Capital is concentrating towards larger, later-stage deals
More than 70% of total UK VC investment flowed into rounds above £25m – the highest level in a decade – signalling a decisive shift toward larger, later stage deals and proven business models.
Scale-up funding remains the UK’s biggest structural weakness
Despite a robust early-stage pipeline, the UK continues to lack sufficient domestic growth capital. Most large rounds rely on international investors, who were involved in nearly half of all UK deals and worth 80%+ of total capital invested in 2025.
The UK is producing more high value companies – but liquidity is tight
The UK added five new unicorns in 2025 (Isomorphic Labs, MUBI, Navys, Tide, Nothing), bringing the total to 29 worth £145bn. Yet exit routes remain dominated by M&A, with 213 exits, only three of which were public listings. Liquidity constraints continue to suppress fundraising recovery.
