Balderton leads $30m round in AI agent security firm

Geordie AI, a purpose-built security and governance platform for AI agents, has closed a $30m Series A funding round as enterprises race to adopt agentic AI at scale.

The round was led by Balderton Capital and also included Crosspoint Capital, alongside follow-on commitments from existing backers General Catalyst and Ten Eleven Ventures.

The raise brings Geordie AI’s total funding to $36.5m. Proceeds will go towards strengthening the platform’s capabilities for security and AI teams, growing its engineering and go-to-market functions, and accelerating its expansion in the United States.

The company has seen rapid commercial traction, reporting 1,300% ARR growth in just the first five months of 2026, and recently took the top prize at the 2026 RSAC Innovation Sandbox competition.

As part of the investment, James Wise, general partner at Balderton Capital, will be joining the company’s board.

Geordie AI operates a platform that gives enterprises real-time visibility into which AI agents are running across their systems, what those agents can access, how they behave, and what risks they introduce. The platform also includes Beam, a runtime remediation suite that uses context engineering to proactively shape and restrict agent behaviour without impeding innovation.

Geordie AI CEO and co-founder Henry Comfort said, “The organizations today that can safely approve and deploy AI agents are the ones that are capturing a new competitive advantage in their space. Geordie enables teams to take a holistic, defense in depth approach so they can deploy their AI agent systems safely at scale.”

Balderton Capital general partner James Wise said, “AI agents are becoming the operating system of the modern enterprise, but security and governance infrastructure has struggled to keep pace. Geordie fills that gap with a purpose-built platform that gives security teams the visibility and control they need to deploy agents confidently and at scale. What gives us particular conviction is the team: we have followed the founders since their time at Darktrace and Snyk, and they understand better than almost anyone how to build behavioral security that works in complex, dynamic environments. We’re proud to lead this round and support Geordie as they become the foundational security layer for the agentic era.”
