Background
Geordie raised a $30m Series A led by Balderton Capital on 28 May 2026, bringing total funding to $36.5m since its September 2025 seed. The company won the RSAC 2026 Innovation Sandbox — the cybersecurity industry's most closely watched startup competition, whose past finalists include Wiz and SentinelOne — signalling it has emerged as the leading institutional answer to AI agent security.
Founded in early 2025 by Henry Comfort (former COO Darktrace Americas), Benji Weber (former senior director of engineering at Snyk) and Hanah Darley (former director of security and AI strategy at Darktrace), Geordie builds runtime security and governance for enterprise AI agents. Its core product, Beam, monitors agent configurations, intended actions and operational environments in real time, feeding contextual policy guidance back into the agent loop rather than relying on static proxy-based blocks. Revenue grew 1,300% in the first five months of 2026 across roughly 30 enterprise deployments including AlphaSense and Owkin.
The funding comes as enterprises race to deploy autonomous AI agents across production workflows while regulators, insurers and security teams push back on the risk of unconstrained agent actions. Geordie's growth rate and investor backing position it as a category-defining bet on agentic AI governance.
