Grown from craftsmanship.
Driven by aspiration.
riemann has grown — from craftsmanship, technology and the desire to do things better every time. Our story shows how toolmaking became real systems expertise.
2026
Handover: Peter and Michael Riemann take over management and lead riemann into the future as system partner.
2025
Expansion of services: The takeover of the 10,000 m² car body shop creates new capacities for integrated solutions.
2020
Generation transition: Peter and Michael Riemann join the management team alongside founder Klaus Riemann.
2017
Investment in growth: A new production hall with a hydraulic tryout press for realistic tests.
2000
Room for further development: Moving to new, larger premises with 1,400 m² production space in Georgsmarienhütte.
1996
Succession in the starting blocks: From small beginnings to big ideas — Peter and Michael Riemann take a look around the plant.
1990
The next step: The location becomes too small – riemann moves to Lengerich and creates space for further growth.
1989
First location: It starts in modest conditions in Lienen near the Teutoburg Forest.
1988
The start: The company was founded by Klaus Riemann in Lienen — with two employees and a focus on toolmaking.
1988
Preparation: Founder Klaus Riemann right before the start of the Riemann GmbH success story.

Continuity in the founder's spirit
Precision, experienced craftsmanship and reliability have characterized riemann right from the start. Like our founder Klaus Riemann, we always think of manufacturing from the point of view of results and see ourselves as responsible for the best possible customer solution. Continuing riemann means maintaining and consistently developing this spirit.
