London-based AI Score has closed a £4m seed round led by Fuel Ventures, with founding investor GALLOS Technologies following on, taking the 2025-founded governance startup's total raised to roughly £4.7m. The valuation was not disclosed.
AI Score was incorporated in 2025 to sell enterprises a live view of what their generative and agentic AI systems are actually doing. The platform inventories AI assets across an organisation, monitors usage, tracks cost and performance, and keeps an audit trail for compliance. For autonomous agents it adds behaviour monitoring and operational controls.
The company is led by chief executive Alex Harland, a member of the founding team at the UK's National Cyber Security Centre, and co-founder Benita Tibb, a former City lawyer. Jonathan Kewley is also named as a co-founder and adviser.
The seed round announced on 4 September was led by Fuel Ventures. GALLOS Technologies, which backed the company at formation, put in further capital rather than allowing its stake to be diluted. The security and resilience specialist raised $50m (£35m) onto its own balance sheet in August in a round co-led by Ventura Capital and Aberdeen Investments.
A group of individual investors joined alongside the two institutions: Alan Morgan, co-founder of MMC Ventures; Mo El Husseiny, managing partner at Ventura Capital and a backer of GALLOS; and Robert Mann, founding partner of Marshall Bridge Ventures. Others came from technology, finance and national security backgrounds.
The round follows a £740,000 pre-seed closed in November 2025, meaning the company has raised roughly £4.7m across ten months. Neither round's post-money valuation has been disclosed, and no ownership split was published.
Reported in euros and dollars, the raise has circulated as €4.6m and $5.4m. The sterling figure of £4m is the one given by the company.
AI Score says revenue grew in the first half of 2026, without publishing a figure. Customers named include Magic Circle law firms, FTSE 250 companies, a UK fintech and global consumer brands.
The advisory bench is unusually senior for a seed-stage company. It includes Sir Jeremy Fleming, the former director of GCHQ; Colin Bell, chair of Starling Bank and previously head of HSBC Bank Europe; and Nick Trim, a Darktrace co-founder.
Proceeds will go towards product development, expanding operations and building out tooling for agentic AI governance, where enterprises are deploying systems that act without a human in the loop.
"AI operates at a scale traditional governance wasn't built for," Harland said.
The pitch lands in a market where compliance obligations are hardening faster than the tooling to meet them. For Fuel Ventures, an early-stage investor with a large UK portfolio, the bet is that governance becomes a line item rather than a project — and that the company selling the ledger of AI activity captures it.
