Two years ago, launching a company out of a UK university lab could mean signing away a third of it before a single outside investor got involved.
That figure has now nearly halved and the story behind the drop says as much about which universities are actually changing their behaviour as it does about the headline number itself.
A Record Low for UK Spinout Equity
The average UK spinout equity stake taken by universities fell to 16% in 2025, down from 25% just two years prior, according to the Royal Academy of Engineering's Spotlight on Spinouts report, built on Dealroom data. It's the lowest figure since records began.
The shift traces back to the 2023 Independent Review of University Spin-out Companies, chaired by Oxford Vice-Chancellor Irene Tracey alongside Cambridge Innovation Capital's Andrew Williamson.
The review recommended capping university stakes at 25% for IP-heavy life sciences spinouts and 10% or under for software a notable pairing, given that one reviewer ran a university system built on spinout output and the other invested in the companies coming out of it.
The government accepted all 11 recommendations, and TenU's USIT Guide gave institutions a practical template to implement them. By 2024–25, universities were averaging 20% in life sciences and 14% in hardware both within the recommended bands.
That's the clean version of the story. The more interesting one is in the variation underneath it.
University Spinout Equity Varies More Than the Average Suggests
Break the 16% average down by institution and the range is wide enough to change the picture. Cambridge, the most prolific producer of VC-backed spinouts in the country with 144 since 2010 (ahead of Oxford's 129), takes an average stake of just 13% over the past five years — among the lowest of any major UK institution.
That's worth sitting with: the university generating the most spinouts nationally is also one of the least demanding on university spinout equity, which undercuts the assumption that higher stakes and higher spinout volume move together.
Southampton offers a clearer before-and-after. In May 2024, its technology transfer office cut its standard IP-heavy spinout stake from roughly a third down to 10%, ending a decade-old policy. David Woolley, the university's Head of Technology Transfer and IP, has framed the logic simply: founder incentives matter as much as investor appetite, and investors tend to pull back once a university's stake passes the 20% mark.
The outcomes back that up. UK spinouts now convert from seed to Series A at a higher rate than the wider UK tech sector — 28.3% versus 27.1% — and the gap widens further at later funding stages.
Where the Value Is Actually Being Created
Deep tech now accounts for the majority of spinout value generated since 2010, and deep tech spinouts make up more than a third of all VC-backed deep tech startups founded since 2019 up from roughly a quarter the decade before.
Oxford still leads on headline exits. Two 2025 deals illustrate the scale: Oxford Ionics, spun out in 2019, was acquired by US quantum firm IonQ for $840 million, and OrganOx was bought by Terumo Corporation for $1.5 billion. Together, those two deals accounted for a third of Europe's six billion-dollar-plus spinout exits that year.
But the UK spinout equity deal story isn't confined to Oxford and Cambridge. Cardiff University claimed the UK's largest spinout financing of 2025 when life-sciences spinout Draig Therapeutics raised a £107 million Series A. Bristol ranks as the highest institution outside the Oxford-Cambridge-London corridor, driven by quantum computing firm PsiQuantum's $2.6 billion raise at a $7 billion valuation in June 2025. In Scotland, Dundee tops the national table largely on the back of Exscientia, the AI drug-discovery spinout that listed on Nasdaq in 2021 at a $2.9 billion valuation.
How Much of the Reform Has Actually Landed
Paul Taylor, enterprise committee chair at the Royal Academy of Engineering, has described the decline in equity stakes as encouraging. Sixty-nine universities have formally adopted the TenU USIT Guide, according to Research England.
That figure comes with a caveat worth taking seriously: Research England no longer actively tracks which universities are following through, so the 69-institution count is essentially self-reported. The Royal Academy's own Enterprise Fellowships data offers a more granular signal as of March 2025, around 11% of applicants were still facing university proposals above the recommended 25% cap.
That fell to roughly 3% by September 2025, and to zero by March 2026, though it's worth noting this reflects one programme's small applicant pool rather than the sector as a whole. Software spinouts remain the clearest laggard, still averaging a 17% stake against a 10% recommendation.
The Equity Question That Hasn't Been Addressed Yet
There's a second layer to the spinout equity deal conversation that's had far less attention: not what universities take, but how founders split what's left among themselves. Among the UK's most successful spinouts since 2010, 63% divided founder equity unequally and founders have consistently reported having little formal guidance on how to do that fairly.
So has the UK genuinely solved the fairness question around UK spinout equity? On the university side, broadly and relatively quickly, yes. Everything downstream of that whether all 69 universities are genuinely holding the line, whether software spinouts catch up to the recommended cap, and how founders divide the equity that remains is still thinly evidenced and largely self-reported. The next Spotlight on Spinouts report should make clear how much of this holds.
