About us


Addvalue is responsible for the investment and transaction management of a single family office, which invests in the areas of health care, real estate, aviation and environment.


Addvalue acquires shareholdings in companies if a sustained added value can be generated and if business areas can be developed 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.



Addvalue is a majority shareholder of an aircraft financer with total assets under management in excess of 3 billion USD.

The growth in air traffic, the necessary fleet modernisation and the expansion of capacities offer long-term investment opportunities (infrastructure) particularly to institutional investors and wealthy families.
