About Us
Industrial companies today face the challenge of keeping production processes running reliably while managing costs, resources and delivery times efficiently. Especially in the field of maintenance, repair and operations, reliable procurement is essential.
thenex supports companies worldwide in meeting these requirements successfully – with solutions that combine operational reliability, cost efficiency, short delivery times and the highest quality standards.
Another key factor is the reduction of complex supplier structures. By bundling procurement through thenex, administrative effort, coordination costs and interfaces can be significantly reduced.
Since its foundation in 1900, thenex has developed from a wholesale company for pipes and fittings into an internationally operating procurement service organisation. More than 125 years of experience, high customer satisfaction and worldwide references stand for reliability, quality and first-class service.

History
1900
The Foundation
From craftsmanship to industrial supply
In 1900, Theodor Nientimp founded the company as a master smith and locksmith. What began with steam engines and drive systems for the local textile industry soon developed into an industrial wholesale business for technical parts. This laid the foundation for more than a century of technical expertise and customer-focused service.
1945–1980
Rebuilding & Growth
A new start for the next generation
After the Second World War, Heinz Nientimp rebuilt the company from the ground up. Following his passing, Elisabeth Nientimp took over the management and led the business for several decades. Under her leadership, the company grew significantly and expanded its product range, while remaining deeply rooted in reliability, responsibility and family values.
1981–1998
The Birth of thenex
From local trade to international procurement
In 1981, Theo-Heinz Nientimp founded thenex Import-Export GmbH as a subsidiary of the family business. With a clear focus on export, procurement and international industrial services, the company began to expand beyond Germany. In 1998, the company was renamed thenex GmbH – marking the beginning of a new chapter as a globally active procurement service organisation.
2009–Today
Expanding Global Reachv
Modern procurement with worldwide expertise
With Henry-Johann and Marten-Theodor Nientimp, the fourth generation joined the company and continued to develop thenex into an internationally operating procurement partner. Today, thenex supports industrial customers worldwide with a strong focus on sales, marketing, procurement and administration. Long-standing partnerships, especially in regions such as the Middle East, Latin America, Africa and Europe, underline the company’s global expertise and reliability.
