Webzites.nl is a company of two Master graduates from the TU Delft, The Netherlands. Jeppe Bijker graduated in the field of Industrial Design Engineering and Marthijn Bontekoning in Wind Energy Engineering.


At Webzites.nl we love to develop custom websites and mobile applications. Currently, we are mainly focussing on apps for wind farms and apps for conferences and business expositions, see the links below. However, if you are interested in a mobile application in a different industry, please don't hesitate to contact us.
