Sven Mahn

Owner and CEO

Sven Mahn has a broad educational background: He is a qualified concrete and reinforced concrete constructor and industrial manager and has a degree in business informatics. From 1999, he was self-employed, first as an IT manager and later in the field of Microsoft Dynamics AX implementation. In 2005 he founded Sven Mahn IT, managing the company as CEO.

I have always refused to focus on a single industry in the firm belief that companies can always learn something from other industries. My motto for life There is nothing I cannot do; anything I cannot do yet, I can learn can therefore also be transferred into projects and the company. Employees, partners and customers benefit from unconventional ideas and the connection between hobbies and professions in all respects. My vision is to implement the best Dynamics for our customers together with my team.
