Our story

Founded on a conviction: service deserves specialists.

OPUSm was founded in Zug in 2014 — on a clear conviction: service processes are too important to digitalise on the side. Instead of covering a bit of everything as a generalist, we focused on one field from day one: service management in the SAP ecosystem.

The first projects in Switzerland grew into international rollouts, individual mandates into long-term partnerships — and recurring customer requirements into products of our own, bundled in the OPUS Extension Suite. In 2024 we opened our second location with OPUSm Deutschland GmbH in Ratingen.

None of that has changed to this day: a team small enough that everyone knows every project — and experienced enough to bring every project safely to its goal.
