Your Agents. Our Architecture.

Primitives, Platform, and People

We have been running AI agents at scale since 2021. Now put that same stack to work on your own use cases.

01

Sumvin

The orchestration layer for identity-anchored money. Verified identity for humans and agents, provable mandates that authorize real work, and one API for every rail — from Visa Intelligent Commerce to direct stablecoin settlement.

  • Sigil — self-sovereign proof of personhood, established once and carried across the stack
  • Errand — scoped, cryptographically provable mandates for spend, data sharing and delegation
  • Atomic Money — card issuing, on- and off-ramps, open banking, payment links and x402
  • Envoy — cloud agents that find, buy and settle within an Errand's guardrails

02

Atlas

The cloud-agents platform for finance. Thousands of agents running against the systems an enterprise already has, not a greenfield demo.

  • Agent orchestration over existing data
  • Real-time processing with an audit trail
  • Runs inside your own cloud and identity boundary
  • Evaluation harnesses so behaviour is measured, not assumed

03

The Studio

Forward-deployed engineers who embed with your team and build the use case on our own stack, through to production.

  • Engineers in your team, not a statement of work
  • Week one starts mid-stack, on Sumvin and Atlas
  • First commit through to first real users
  • We stay after launch; it is not a handover
