The CU Story

CU was formed in 2020 from the merger of Xengoo Consulting GmbH and Coders Unlimited GmbH.
Xengoo Consulting was founded in 2013 by Uwe Freese and Jan Steinbach as a B2B consultancy with a focus on inbound content marketing and was one of the first HubSpot partners in Germany. For the programming of complex web projects, such as multi-language corporate websites or shop platforms, Xengoo worked intensively with Coders Unlimited. Over the years, this collaboration developed into a close partnership with Coders Unlimited and its founder Thorsten Scherff.

2020: 1+1=3

In 2020, the "logical" step followed: the merger of Xengoo and Coders Unlimited. Under the brand "CU" the services of both companies were restructured. The result was a new company with a unique value proposition around the topic of DIGITAL SALES-MARKETING.

The three Managing Partners also stand for the three company divisions: CONSULTING, SOLUTIONS and SERVICES. The CU business proposition has already proven to be relevant from the start. Despite the COVID-19 pandemic, CU achieved an increase in turnover of approx. 40 % in 2020.
