UK Startup Funding Report: £121.6m raised across Healthtech, AI and Greentech (20–24 Apr 2026).
It's Friday, 24 April, and this is your UK Startup Funding Report.
Investors put £121.6M into UK startups this week, with large rounds in AI, greentech and healthtech. Deals ranged from a £53m growth raise for Cloudsmith to several early-stage AI and clinical funding rounds.
AI shifts from experiment to production
Investors are directing capital towards startups that make AI reliable and deployable rather than simply demonstrative. This week’s activity highlights funding for agent frameworks, developer and on‑device inference infrastructure, and enterprise AI deployments as companies move systems out of the lab and into production. The change is driven by the need for governance, security and predictable costs as AI increases volumes of code and artefacts.
Major deals underline that trend. Cloudsmith raised £53 million in a growth round led by TCV to accelerate product development and expand go‑to‑market as AI‑generated code increases artefact volumes. DOJO AI secured £4.44 million from Armilar to deepen its multi‑agent marketing platform, fund the DOJO Graph and agentic marketing agents, and push into the US. Lua took £4.29 million from Norrsken22 to build an operating system for human–agent collaboration designed to avoid vendor lock‑in while scaling agent workforces alongside human staff. Locai raised £1 million from Fuel Ventures to commercialise on‑device inference that keeps model execution local to laptops and workstations, targeting SaaS and desktop AI vendors that want lower cloud costs and improved privacy.
The pattern is consistent across stages: investors favour infrastructure and enterprise tooling over flashy demos. From growth rounds to small seed tickets and crowdfunding caps, capital is flowing to companies that prioritise reliability and production readiness.
