Outerlimit Exits Stealth With $16M Pre-Seed to Build Zero-Trust Security Layer for Autonomous AI Agents

London- and New York-based Outerlimit emerged from stealth on September 22, 2026 with $16 million in pre-seed funding to build a zero-trust security layer that prevents rogue autonomous AI agents from causing harm.

Outerlimit, headquartered in London and New York, emerged from stealth on September 22, 2026, with $16 million in pre-seed funding from AlbionVC, Evolution Equity Partners, and Crane Venture Partners to build a security layer for autonomous agentic AI. The platform follows a discover, observe, and enforce model: discovery covers agents, tools, MCP servers, and shadow AI, followed by observation and then enforcement. Its zero-trust approach fragments credentials and reconstructs them only after an agent's identity, policy, and execution context are verified, so off-policy tool calls are denied — binding identity, authorization, and action into a single operation. The company says this sidesteps alignment problems by treating all agents as potentially misaligned and enforcing predefined policies externally. Founders Tony Pepper and Neil Larkins previously led Egress, which was acquired by KnowBe4 in 2024. The announcement included no independent tests or customer deployments, so claims of provable control and zero credential exposure remain unverified vendor claims.
