Dr. Matthias Zimmermann

Dr. Matthias Zimmermann

Matthias is co-founder and board member of the HIAMO brand, which he launched together with Marco in February 2021. As a doctor of real estate economics, he is responsible for the real estate, construction and expansion of the HIAMO brand. His focus is on the valuation of the hotel properties and their future direction in terms of real estate.

After spending time abroad in Seville and Harrisonburg, USA, Matthias studied international, bilingual business administration, real estate economics and marketing at the European Business School in Oestrich-Winkel, which he completed with a doctorate. Afterwards, in 2005, he took over the family business Weser-Wohnbau GmbH & Co. KG in the 2nd generation and still successfully leads the company today as managing partner.

At the same time, he got to know Marco and thus the world of the hotel industry. Both Hanseatic men had the vision of an individual, extravagant and at the same time affordable hotel concept and founded the budget design hotel brand prizeotel from this idea in 2006. As an experienced and successful real estate economist, Matthias was the managing director responsible for real estate development and construction.

Three years later, Matthias and Marco opened the first prizeotel in Bremen and received the Bremen Founders Award in the same year. Further awards and prizes followed in the areas of hotel concept, design and quality.

His heart beats for real estate with atmosphere – so his passion did not end when prizeotel was sold to the Radisson Hotel Group in 2020.

In 2021, Matthias and Marco combined their ideas and visions again and founded the HIAMO brand. As a doctor of real estate economics with vision in the hotel industry, Matthias concentrates on the profitability and real estate expansion of the brand.
