Outerlimit, a newly launched decentralised security and authorisation company built for agentic AI, has come out of stealth with $16m in pre-seed backing.

AlbionVC, Evolution Equity Partners and Crane Venture Partners supplied the capital. A group of strategic angels also joined, including Alan co-founder and CTO Charles Gorintin, who is also a co-founding advisor at Mistral, ReliaQuest founder and CEO Brian Murphy, A-lign founder and CEO Scott Price, and Goldman Sachs global head of client coverage for Global Banking and Markets Sam Morgan.

They are joined by FTV Capital partner Kyle Griswold, Twin Track Ventures partner Nicola Sinclair, Garrison founder and CEO David Garfield, whose business was bought by Everfox, and GP Bullhound co-founder and managing partner Manish Madhvani.

The raise lands as businesses hand AI agents growing access to their systems, data and APIs. According to Outerlimit, today’s tools for identity and access management, runtime enforcement and AI governance fall short of delivering the verifiable oversight and control needed for organisations to expand agent deployments without taking on unmanaged risk.

The company’s answer is to push Zero Trust principles down to the level of individual agent actions, something it says has not been done before. Its distributed design applies cryptographic enforcement at the point a tool is called.

Credentials, keys and secrets are never held in one place; instead they are split into fragments spread across the agent environment, and they can only be pieced back together when a tool is triggered. Decryption happens solely once identity, policy and execution context have all been confirmed, meaning each action is cleared before it runs.
