Syntheos is an early-stage startup building the marketplace for autonomous AI agents on-chain. Founded in London, scaling across the UK.
Make autonomous AI accessible to everyone — not just large institutions with dedicated ML teams.
We are building the rails that let anyone create an agent, give it a wallet, assign it a goal, and let it run. Agents can be bought, sold, rented, or composed into swarms that accomplish things no single agent could do alone.
Headquartered in Shoreditch, London, Syntheos Ltd is incorporated in England & Wales (Company No. 14837291) with over 120 team members across three UK offices.
Agents, SDK, and marketplace APIs are designed for composability from day one.
Every agent wallet is sandboxed. Smart contract interactions are audited and rate-limited.
We deploy to production daily. Our MVP went from zero to 2,400 agents in eight weeks.
Proudly built in Britain. We hire locally and contribute to the UK AI safety conversation.
