What we stand for
Experience-driven performance
Since 1919 we have continuously refined our supply chain — quality control, contracting, logistics, financing and risk. Customers reach us with a single phone call, and we own the outcome from origin to mill.
Next-generation technologies
Truly sustainable cotton requires modern practices. We support partners across origins with knowledge transfer, agronomy data and access to the certifications that the spinning industry demands.
Innovation-driven solutions
Standing still is not an option. We continuously rework our processes and instruments to give clients dependable, transparent and resilient sourcing — through every market cycle.
From our management
Organic cotton is good in two ways — good for the environment, and good for the people. We love to be part of this.
Our 100-year company history is characterised by a healthy mixture of traditional values and future-oriented ideas. Reliability meets innovation. This applies to our passion in cotton as well as to our appreciation and connection towards employees, suppliers, customers and business partners.
A century in cotton
From a single export office on the Weser to one of Europe's leading cotton merchants.
Founded in Bremen
On 1 October 1919, Otto Stadtlander founds an export house in Bremen. The young firm supplies consumer goods of all kinds to North Africa and South America — laying the network on which today's cotton trade was built.

Rainer Hammer joins Otto Stadtlander and begins three decades of close collaboration with the founding generation — preparing the company's eventual succession.
Marcusallee 3 — the former French consulate
In October 1984 the company moves into its present headquarters: the stately villa at Marcusallee 3, formerly the French consulate to Bremen, near Rhododendron Park.
