Outerlimit raises $16.1M Pre-seed

AlbionVC is listed as lead investor, with Evolution Equity Partners and Crane Venture Partners also in the round. Several angel investors took part as well, which brings the total to 11 investors. No valuation was given. The London company came out of stealth the same day. Two of the founders, Tony Pepper and Neil Larkins, led Egress Software to its 2024 sale to KnowBe4. The third, CTO Peter Vincent, is a theoretical neuroscientist trained at UCL.

The product applies Zero Trust to individual agent actions. Credentials and keys are split into fragments across the agent environment and reassembled only when a tool is triggered. Vincent says the platform is generally available and already deployed in live enterprise environments. Most of the money will go to product development and engineering.

For agent builders, this round suggests authorization is turning into its own infrastructure layer. Enterprise buyers are likely to start asking for controls on each action an agent takes, not just on login. It also shows investors will pay Series A-sized sums at pre-seed for repeat founders who already have a live product.
