Carsten Osswald
Managing Director

Carsten is co-founder and Managing Director of PATRONAS and since then, our customers have profited from his vast practical experience in the AM industry. During his time as CEO of an AM company, the lack of a suitable portfolio and risk management software inspired him to initiate the development of OPUS, which could finally fulfil his requirements for a functionality-rich and powerful solution for advanced portfolio, risk and compliance management.
