Konstantin Vinogradov, Steven Bartlett, Gareth Williams, Tom Gozney, Hugo Rodger-Brown and Andy Gray were the most visible individual angels in March 2026. Their deal activity clustered around AI-led startups and adjacent HRtech plays, with a secondary theme of ecommerce and product-led consumer businesses. Several are operator angels and repeat founders, notably Gareth Williams and Tom Gozney, while Steven Bartlett stands out as a high-profile public figure and Konstantin represents a VC-affiliated angel. Taken together, these patterns show UK angels doubling down on AI and talent-facing tooling and using sector expertise to complement capital flows into early-stage rounds.

Fuel Ventures and SFC Capital were the most active firms in March, with IQ Capital, BackedVC and Haatch also registering notable activity. The month was led by AI and healthtech, with solid deal flow across fintech, property and agricultural technology, advanced manufacturing and greentech. That breadth indicates a cross-sector appetite rather than a single hot theme. Specialist models and regional ecosystems were prominent: university spinouts, British Business Bank co-investment structures and public regional support featured across deals. Together, these flows point to a resilient UK venture market in which early-stage discovery in AI and healthtech is being backed by a widening ladder of follow-on capital, aligning with the strategic motives common to corporate investors such as industry adjacency, R&D alignment, regulatory or clinical focus and infrastructure-scale commitments.
March’s corporate-backed activity was led by a mix of established CVCs and pragmatic banks. ABN AMRO’s Sustainable Impact Fund, bp Ventures and Johnson & Johnson Innovation (JJDC) sat alongside the Scottish National Investment Bank and challenger bank investor N26. Funding clustered into three clear sectors: biotech and healthtech (Mestag, Bioliberty), industrial energy and mobility (Oxa), and sustainability-led agtech plus fintech/regtech (Tropic, Diligent AI). The presence of banks as active, strategic investors reinforces that non-traditional corporate vehicles are now core players, with moves focused on protecting R&D, backing industrial adjacency and underwriting commercial scale-up.
