About us


Addvalue is responsible for the investment and transaction management of a single family office which invests in the health care, real estate, aviation and environment sectors. Addvalue acquires shareholdings in companies in order to generate sustained added value and to actively develop business areas in close cooperation with the management.

Real Estate


Addvalue advises several family offices in the development of real estate investments and the implementation of specific strategies.

Health Care


Addvalue responds to the challenges of demographic change by investing in health care properties for the long term, thus creating additional services in nursing homes, assisted living facilities and needs-oriented living quarters/neighborhoods. As a reliable investor, Addvalue supports institutional partners from the early stages of project development.



Within the scope of selected mandates, Addvalue provides national and international investors with investment opportunities and advises on questions of strategic business development.


The growth in air traffic, the necessary modernisation of fleets and the planned expansion of airline capacity offer institutional investors in particular long-term investment opportunities in infrastructure projects.



Reliability and meticulous attention to detail are the cornerstones of our corporate philosophy. We support our partners and clients with comprehensive know-how.
