The UK’s Most Funded Startup Sectors: An Analysis of 3,023 Companies

AI is everywhere, but fintech has raised more 

We currently track 644 funded UK AI startups, more than in any other sector examined. Collectively, they have raised approximately £13.76 billion. 

AI is unusually difficult to treat as a standalone sector. A company providing AI fraud detection software to banks could reasonably sit under AI, fintech, SaaS and data. 

As we have added companies to the database, we have seen AI become less of a distinct industry and more of a technology running through the wider startup ecosystem. It now appears across healthcare, financial services, legal technology, manufacturing and climate technology. 

Fintech contains slightly fewer funded companies. We track 624, but together they have raised approximately £17.44 billion. 

That is nearly £3.7 billion more than AI and works out at around £28 million per tracked fintech company, compared with approximately £21 million for AI. 

These averages can be pulled upwards by a handful of large rounds, so they should not be mistaken for what a typical startup raises. They nevertheless demonstrate the scale of capital that has entered UK fintech. 

Biotechnology is smaller but capital-intensive 

Startupmag tracks 250 funded biotechnology companies, less than half the number found in AI, fintech or healthcare. Yet these businesses have collectively raised approximately £6.16 billion. 

That is nearly £25 million per tracked company, putting biotechnology behind fintech but ahead of AI on this measure. 

Biotechnology businesses may need years of research, testing, specialist facilities and regulatory work before producing meaningful revenue. The sector’s relatively small company count therefore hides how much funding can be required to turn scientific research into a commercial product. 

Healthcare combines scale and variety 

Healthcare sits close to AI and fintech by company count. We track 627 funded healthcare startups, which have collectively raised approximately £9.90 billion. 

The category includes medical devices, diagnostics, clinical technology, care delivery and health software. Digital health alone accounts for 152 companies in the database. 

The range of companies shows that funded healthcare innovation is not confined to laboratories and drug development. Investors are also backing companies trying to improve how patients access care, how clinicians work and how health information is managed. 

SaaS and greentech broaden the picture 

We track 365 funded software-as-a-service companies, with £5.58 billion raised collectively. SaaS remains a popular model, although the boundary between SaaS and AI is becoming harder to draw as software businesses add intelligent automation to their products. 

Greentech is smaller, with 210 funded companies and approximately £2.85 billion raised. It is another difficult sector to categorise neatly, spanning renewable energy, carbon reduction, circular materials, environmental monitoring and sustainability software. 

What should founders take from this? 

The data does not suggest founders should rush to build an AI or fintech company. It shows that the UK funding market is broader than any single trend. 

AI has produced the largest population of funded startups. Fintech has attracted the most capital. Biotechnology stands out for the amount raised relative to its size. 

For founders preparing to raise, the useful question is not simply which sector receives the most money. It is which investors already understand their particular market, stage and business model. 

Following the largest trend may attract attention. Being genuinely relevant is more likely to start a serious conversation. 

Methodology: Figures are based on disclosed funding amounts recorded in Startupmag’s database of 3,023 funded UK startups on 30 July 2026. Funding totals are cumulative rather than limited to 2026. Categories can overlap, and averages may be affected by exceptionally large rounds.
