About

The engineering partner behind regulated European fintechs.

We are a specialized engineering boutique bridging the gap between fast-moving fintech platforms and rigid national payment rails. You focus on your product and customer acquisition; we build the bank-grade backend plumbing — architect-led — engineered to pass the strictest Cantonal bank security audits.

Architect-led delivery

An architect owns the system design, security model, and compliance mapping. Engineers build against that blueprint — so quality and risk are controlled from the top down.

Swiss-market track record

Our work runs in production in one of the world’s most regulated banking markets — and has passed the security audits that come with it.

Discreet by default

We work under strict NDAs and white-label terms, and never publish client names. The work speaks for itself; the names stay private.
