A new report from CB Insights highlights how a small group of investors is steering the UK’s insurtech sector toward greater commercial success, even as broader venture funding tightens. Released recently this month, the analysis ranks the top 25 most active backers of UK-based insurtech startups and examines what their investment choices reveal about the industry’s future.
UK insurtech continues to punch above its weight. In 2025, 11 percent of equity deals in UK-based insurtech companies went to startups ranked in the global top 1 percent by CB Insights’ Mosaic Score—a predictive metric of future success.
That compares with just 5 percent across the entire UK startup ecosystem, underscoring insurtech’s ability to produce high-potential companies despite challenging market conditions.
From more than 400 investors who participated in UK insurtech equity deals between 2021 and 2025, CB Insights identified a select group of 25 using proprietary signals such as business relationships and Mosaic Score performance.
Collectively, these top investors have driven 97 unique deals, shaping the sector’s trajectory at a time when capital is becoming scarcer.
Their portfolios stand out for stronger commercial traction.
Among pre-exit companies backed by these investors, 52 percent have reached “Scaling” or “Established” status on CB Insights’ Commercial Maturity scorecard—15 percentage points higher than companies without top-investor support.
This edge points to a clear advantage: startups chosen by these discerning backers are far more likely to move beyond early promise into sustainable growth.
Hiring data reinforces the picture of accelerating maturity.
Of the 17 portfolio companies currently classified as “Scaling,” 14 employ at least 50 people and have posted a median headcount growth of 18 percent over the past 12 months.
For founders and executives, the message is clear—securing capital from these elite investors increasingly signals a viable route to operational scale and long-term viability.
Yet the report also flags intensifying headwinds.
The number of active investors has declined, competition for deals has sharpened, and median early-stage insurtech funding sizes fell in 2025—contrary to trends in the wider venture market.
In this environment, top investors are concentrating bets on companies that already demonstrate product-market fit and revenue momentum rather than speculative concepts.
The findings carry important implications for the broader insurance industry.
As incumbents seek innovation through partnerships or acquisitions, the startups most likely to deliver measurable value are those already backed by this influential group.
Entrepreneurs raising capital should view alignment with these investors not merely as a funding milestone but as validation of their path to commercial relevance.
By spotlighting the investors most attuned to UK insurtech’s evolving needs, CB Insights offers a data-driven roadmap for an industry in transition. While deal flow may remain constrained, the companies that attract this top-tier capital appear positioned to thrive—delivering the scalable solutions that insurers and policyholders demand.
