Ex'tent BV (Ex'tent) is the venture capital subsidiary of Extent Holding BV, itself a subsidiary of Wintzen Management Co. BV in the Netherlands. Founded by Dutch IT entrepreneur Eckart Wintzen in 1996, the name of the firm derives from 'Eck's shack'. Ex'tent is located in Austerlitz in the province of Utrecht in the central Netherlands. The firm aspires to sway the correlation between the growing wealth of the western world and the depletion of natural resources worldwide, the impoverishment of poor populations and the global environmental crisis. A self-described 'company with a conscience', Ex'tent aims to contribute to orienting the western free-market economy towards increased global fairness and environmental sustainability. The firm supports both commercial enterprises and non-profit organizations in which Ex'tent is not a shareholder. Ex'tent operates in close relationship with Probel Capital Management NV, a Belgian corporate finance advisory and venture capital partnership, as well as with Probel's wholly-owned subsidiary Bosschuur Capital Management BV. Boschuur manages the green venture capital fund Ex'tent BV and shares premises with Ex'tent.
