Who we are

Hoofbosch investment fund was founded in 2006 by Martien van Winden and Robbert-Jan Engels, after years of successfully managing a family fund.

Martien van Winden (1957) has a passion for history, philosophy, and economics. He started his career at Robeco. He was also a guest lecturer in strategic management at the VU University, University of Amsterdam and Erasmus University Rotterdam. In 2000 he published his bestseller 'Staying Rich'. His passion for history has resulted in a graph: The Financial Canon of the Netherlands, which charts the development of shares and interest from 1540 onwards. His latest book 'Your age as a goldmine' was published in 2020. Martien has an MBA from Nyenrode Business University.

Robbert-Jan Engels (1958) shares Martien's passion for history. Robbert-Jan studied law at Erasmus University Rotterdam and held various consultancy and management positions at, among others, engineering firm Arcadis. Afterwards he was director-owner of Fiscaal Raadhuis, a tax consultancy for the local government. He is co-author of the book 'World at a turning point', in which current events are analyzed in a historical perspective. Within the fund’s management board, Robbert-Jan is primarily responsible for risk management and compliance. Together with Martien, he regularly visits listed companies at home and abroad.

Martien and Robbert-Jan are supported by a team of five professionals.
