AI agents for business teams
Agents that take repeated work off finance, sales, customer service, operations and HR: inbox triage, invoice processing, reconciliation exceptions, reporting packs, lead intake, document extraction and data entry between systems. Each agent has one job, an owner and its own permissions. It reads prepared data and changes records only through a separate channel with confirmation (MCP servers). A person approves anything that sends, pays or touches a customer, and every action is recorded.
Pilots
Transfers, FX and Clearing (1-3 months to a working pilot); Wallets and Embedded Finance (2-4 months); Transaction and Crypto Gateway (1-2 months); AI Agents & Automation (2-4 months).
Selected work (clients under NDA)
- SEPA Instant on ISO 20022 for an EU-licensed payment institution.
- A US prepaid card program on one cardholder experience.
- A transaction-signing SDK for PSD2 SCA inside a bank's app.
- Buying, selling and holding digital assets inside a bank's app.
- A wallet platform across 7 blockchain networks.
- A debt-collection platform across 4 EU jurisdictions.
