Geordie AI, a London-based startup which provides a security and governance platform for AI agents, has raised a £22.4 million Series A round led by Balderton Capital. The round, according to calculations based on filings with the British business registry Companies House, values the startup at about £134.4 million post-money. It is believed to be the largest Series A round for a cybersecurity startup in Europe to date.
The round also includes new investment from Crosspoint Capital and follow-on funding from existing backers General Catalyst and Ten Eleven Ventures. The new investment brings the total Geordie has raised to date to £27.2 million and comes less than a year after the company first emerged from stealth with a £4.85 million seed round in September.
The startup, which was cofounded by veterans of the U.K. cybersecurity company Darktrace and Snyk has caught the attention of the cybersecurity industry. Geordie won the 2026 RSAC Innovation Sandbox contest in March, which is closely watched startup competition for cybersecurity companies, whose past finalists have included Wiz and SentinelOne.
Geordie is now deployed across roughly 30 customer environments, and cofounder and CEO Henry Comfort stated: “We believe agents are going to change the nature of work. [They are] going to need purpose-built security and governance capabilities.”
Comfort co-founded Geordie in early 2025 with Hanah Darley, the former director of security and AI strategy at Darktrace, where Comfort previously served as COO for the Americas, and Benji Weber, the former senior director of engineering at developer-security firm Snyk. Weber is now Geordie’s chief technology officer, while Darley is its chief AI and product officer.
The company currently has 37 employees split between offices in London and New York, and Comfort said he expects headcount to reach about 50 in the next three months. Money from the Series A funding round will be used primarily to expand engineering and U.S. go-to-market teams.
