We've been building payments infrastructure for over a decade.
Rootline is what we wish we'd had from the start.

Rootline is what we wish we’d had from the start.
Our team has founded and scaled some of Europe's biggest fintechs. The last generation of payments infrastructure? We helped build it.
But we watched platforms outgrow what we'd built. The architecture was designed for linear transactions. Platforms needed recursive splits, dynamic fees, multi-party payouts, and cross-channel reconciliation without workarounds.
So we started over. Rootline is a financial engine built from scratch for the way platforms move money today.

Most payment providers were designed for simple, one-to-one transactions. They added platform features later: subaccounts, splits, marketplace payouts. But the foundation was never rebuilt. The result is rigid account hierarchies, manual reconciliation workarounds, and engineering teams spending more time maintaining their payment stack than building their product.
We started with the platform use case and worked backwards. One API. One data model. One financial truth. From the simplest webshop to the most advanced multi-party business model, without the usual complexity.
