Our team

Matthias Wittenburg

Matthias Wittenburg
Managing Partner

Matthias Wittenburg is the Founder of COMPANYLINKS.

Following over 25 years in international banking, he founded a corporate consulting firm in 2017 with the aim of assisting medium-sized enterprises in their quest to secure investors or followers. Over time it had become clear to him that this process tends to be rather inefficient. This gave him the idea for COMPANYLINKS in 2018.

Matthias first trained in banking and later obtained a Master’s degree in Business Administration from Cardiff University. He is also a graduate of the Oxford Advanced Leadership and Management Programme (OALMP) at the Saïd Business School and took part in the 129th Baden-Baden Entrepreneurs’ Talks. Together with running his own business, Matthias Wittenburg is Chairman of the Board of diligent technology and business consulting AG and undertakes various activities on a voluntary basis, e.g. as a guest lecturer at the German Armed Forces Leadership Academy and the Arbeitskreis Evangelischer Unternehmer. In the near future he will take up the post of Honorary Consul to the Republic of Namibia in Hamburg.

What he likes about COMPANYLINKS: being able to work with a great team to set up something that the market has really been missing!
