Cybersecurity startup Geordie raises £22m led by Balderton Capital with General Catalyst
This article covers Geordie, a cybersecurity startup, raising £22m in a series A growth funding round led by Balderton Capital with participation from Crosspoint Capital and follow-on investment from General Catalyst and Ten Eleven Ventures. The funding supports expansion of Geordie’s engineering and go-to-market teams and US operations, and the product targets security and IT teams needing visibility and runtime controls to manage risks from AI agents.
Geordie, a cybersecurity startup, has raised £22 million in a series A — a growth funding round — led by Balderton Capital, with participation from Crosspoint Capital and follow-on investment from General Catalyst and Ten Eleven Ventures. The capital will be used to expand engineering and go-to-market teams and to grow Geordie’s US operations; the new injection brings the company’s total funding to $36.5 million.
Why it matters
Enterprises are rapidly adopting AI agents to automate workflows and surface insights, but many security and IT teams lack the visibility and governance controls needed to manage the new attack surface. Geordie addresses that operational gap by mapping agent behaviour and access in real time and offering runtime controls to constrain unsafe actions.
The problem is not hypothetical. Owkin, an AI-driven drug discovery and biomedical research company running hundreds of agents across more than 50 petabytes of data, says a single Geordie proof of concept averted exposure it estimates at $12 million to $13 million. Geordie also signals fast market traction: the company reports 1,300% ARR growth in the first five months of 2026 and was the winner of the 2026 RSAC Innovation Sandbox.
Inside the product
Geordie’s platform focuses on three practical needs for production agent deployments: discovery, behavioural visibility, and automated remediation. It scans enterprise systems to identify active agents, maps what data and services they can reach, and monitors their actions to highlight risky behaviour. The company’s Beam runtime remediation suite applies what it calls context engineering to shape agent decisions — limiting actions that could cause data leakage or unauthorised access without blocking legitimate innovation.
That approach is pitched at security and IT teams that need defence in depth for agentic systems: detection and continuous monitoring, combined with runtime controls that intervene before a breach occurs. Geordie says its product is intended to sit alongside existing security tooling rather than replace it, integrating into enterprise environments to provide an additional governance layer.
Who are the investors?
The round was led by Balderton Capital, with Crosspoint Capital participating and existing backers General Catalyst and Ten Eleven Ventures providing follow-on funding. The new financing follows an earlier seed round and takes Geordie’s total raised to $36.5 million. As part of the deal, James Wise, Partner at Balderton Capital, will join Geordie’s board.
Mark Crane, Partner at General Catalyst, said:
When we backed Geordie at seed, agentic AI security was still a hypothesis. In just six months, AI agents have moved from pilot to production faster than most enterprises were ready for. Geordie's growth in that short time confirms that Henry, Hanah, and Benji correctly identified that trajectory and we are excited to continue to invest in them.
James Wise, General Partner at Balderton Capital, 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 behavioural 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.

Founder perspective
Geordie was founded by alumni of Darktrace and Snyk. The team points to rapid customer adoption as confirmation that the market has moved quickly from experimentation to production for agentic AI. The company plans to use the funding to beef up engineering and to accelerate sales and support in the US market.
Henry Comfort, Co-founder & CEO, said:
For us, AI agents are a necessity to our competitive advantage. We chose Geordie because of its purpose-built approach, which doesn't risk the business innovation that started our AI agent journey in the first place. We're seeing the iceberg that rocked the Titanic weeks in advance rather than the moment it appears on screen.
Leo Cunningham, CISO, Owkin, said:

The bigger picture
Geordie’s raise sits at the intersection of two clear trends: rapid enterprise roll-out of agentic AI and an emerging market for purpose-built security tooling that understands autonomous behaviours. For UK cybersecurity startups, the deal illustrates continued investor appetite for companies that pair security domain experience with product-led approaches to operational risk.
The emphasis on US expansion is also notable. Many UK-founded cybersecurity companies scale by selling into larger US enterprise accounts once product-market fit is proven at home; this funding round follows that familiar playbook while signalling that investors see agent governance as a high-priority problem.
As AI agents become more embedded in business processes, expect more specialised tooling and governance frameworks to emerge across Europe. Geordie’s funding round suggests that investors and customers alike are already treating agent security as a production-grade challenge rather than an experimental add-on.
