Why we built Cortena: 400 conversations, one pattern, and the problem everyone accepted as normal

Before writing a line of code, we spent a year talking to finance leaders across Europe. The answer they kept giving us was the same.

Cortena now connects to 1,000+ European banks and reconciles 5,000+ invoices a month at close to 90% accuracy via agent-based workflows.

Finance teams do not struggle for lack of dashboards. They struggle because upstream work, invoices, approvals, and reconciliations, is still manual.

Most finance AI works in demos and fails on real ledgers. Agent-based reasoning is the architecture that fixes it.

Dashboards give finance teams more data but less clarity. CFOs are moving to conversational AI that answers in plain language.

The fastest way to understand Cortena is to see it run on your real books.
