Bank-Grade Fintech Infrastructure.
We build white-label payment ecosystems and eBill integrations that pass rigorous Swiss bank security audits.
Engineered on the EBICS, QR-bill and ISO 20022 standards that run Switzerland's national payment rails — the same rails used across Germany, France, Switzerland and Austria.

The secure partner layer.
An anonymized view of how we bridge a core banking system to the national eBill network — the seam where security audits are won or lost.
