Nicolas Kopp and Stelios Modes started Rillet in 2021, and the product launched publicly in 2024. The team’s starting frustration was familiar to finance operators: manual reconciliation, difficult ERP migrations and systems that businesses repeatedly outgrow.
Rillet brought accountants and engineers together to build a ledger around automation from the outset. Its stated ambition is a zero-day close, with financial information available as events happen. Traceability and human review remain part of that design: entries connect to their sources, while finance teams retain oversight of the work performed by agents.
