Geordie AI, a London-based startup which provides a security and governance platform for AI agents, has raised a $30 million Series A round led by Balderton Capital.

Geordie won the 2026 RSAC Innovation Sandbox contest in March—a closely watched startup competition for cybersecurity companies, whose past finalists have included Wiz and SentinelOne.
Geordie is now deployed across roughly 30 customer environments, cofounder and CEO Henry Comfort told Fortune.

Comfort co-founded Geordie in early 2025 with Hanah Darley, the former director of security and AI…
