About us

MAM-Partners AG

The founders of MAM-Partners come from the financial industry and are experienced economists, asset managers, founders, and entrepreneurs. Since 2000, they have been involved in building more than ten asset management boutiques that by now manage assets in excess of € 25 billion.

For 15 years, we have been successfully breaking new ground in the way we build companies and design their compensation models. We help to build a value-unfolding corporate culture that makes every company more attractive and valuable for founders, employees, and shareholders.

We are actively supported by our Supervisory Board and Advisory Board – made up of experienced and recognized capital markets personalities  as well as the founders of our portfolio companies. All in all, a strong network.

This is our contribution to unfolding values.


Matthias van Randenborgh

Matthias van Randenborgh is characterized by his enthusiasm and constant drive for innovation airing to try something new. As early as the 1990s, the 53-year-old business graduate and Master in Banking and Finance delved into the effects of ownership structures on the success of companies. As a result, he established the human capitalist approach for his ventures. His master’s thesis appeared in the Journal of Finance in 1994 and was awarded the Smith Breeden Prize. He continued to break new ground in his professional career. After seven years in derivatives trading at two major banks, he became a serial entrepreneur. He was founder and CIO of the asset management boutiques Vescore, LPX, CYD and RP Crest. Now he is setting out again to break new ground with the incubator MAM-Partners.

In his private life, the father of two enjoys sophisticated conviviality with a philosophical touch. He likes challenging conventions and traditions and to think the world differently – for a change.


Christian Mardeck

His ability to approach tasks in a structured manner and to think strategically, interdisciplinarily and with vision have brought the 46-year-old, who has more than 20 years of professional experience, into management positions early on. He was Head of Product Development at BayernInvest Munich and Managing Director of BayernInvest Luxembourg, and from 2012 to 2020 Managing Director of RP Crest GmbH. After working as Managing Director at PIA Pontis, a consulting firm focused on real assets, he has been a board member and co-founder of MAM-Partners. There, he wants to contribute his strengths as an entrepreneurial thinker as well as his experience and know-how in asset management to develop the incubator MAM-Partners into a successful and recognized asset management platform.
