London-based AI Score announced a $5.4 million (£4 million) seed round on September 3, led by Fuel Ventures with continued backing from founding investor GALLOS Technologies, plus angel participation from Marshall Bridge Ventures founding partner Robert Mann, Ventura Capital managing partner Mo El Husseiny, and MMC Ventures co-founder Alan Morgan. The round follows a £740,000 pre-seed the company raised in November 2025.

What the product does

AI Score was founded by CEO Alex Harland, who was part of the founding team at the UK's National Cyber Security Centre, and Benita Tibb, a former City lawyer. The company's platform sits between an organization's written AI policies and the actual systems, employees, agents and workflows using AI day to day. It continuously collects and analyzes AI activity across a company to build a live inventory of AI assets, assigns ownership and risk profiles to each one, and maintains an audit trail of usage. For AI agents specifically, the platform adds controls that let organizations see what an agent is doing and restrict what it can access, connect to, or act on — aiming to close the gap between policies written on paper and agents that are already wired into internal tools and data.

Why now

AI Score says revenue grew strongly through the first half of 2026, with demand coming from law firms, a FTSE 250 company, a UK fintech and several global consumer brands — customers for whom unmonitored use of generative and agentic AI carries compliance and data-exposure risk. That traction lines up with a broader shift enterprises are making this year: from experimenting with individual chatbots to running fleets of semi-autonomous agents across departments, often faster than security and compliance teams can review what those agents are permitted to touch.

Why it matters

AI Score is one of a growing number of agent-governance and agent-security startups — alongside firms like AIR Security, which raised its own $50 million seed round earlier this month — that investors are betting will become a durable category as agent deployments scale. The founders' backgrounds in national cyber-security and corporate law point to a specific niche within that category: less about blocking malicious third-party plugins and more about giving compliance, legal and security teams continuous visibility into what agents are doing inside a company, and a paper trail to show regulators and auditors when something goes wrong.
