Why SENN Gruppe

Four reasons our customers
have stayed with us since 2001.

SENN was founded to simplify industrial procurement. The core principles hold today as they did more than two decades ago.

One point of contact

One order instead of eight procurement negotiations. Personal account management per customer — also for re-orders, complaints and special requests.

The group · Holding + 9 subsidiaries

Nine specialised
companies. One contact.

Each subsidiary is an independent expert in its field — with its own production, its own employees and its own invoicing. You tell us what you need — we take care of the rest: coordination, delivery, re-orders.
