Systems Development

Transmark Systems

Transmark Systems actively participates in companies with the ambition to change the future. The enthusiastic people within these organizations all have their own idea of how their technology or products can change the way we work or do business.

The developments are often related to reducing CO2 emissions and thus limiting the use of hydrocarbons as raw materials.
Museum of the Canals

Het grachtenmuseum

The company’s headquarters also houses Het Grachtenmuseum, in the centre of the stunning canal ring of Amsterdam. In five interactive rooms, you can witness the history of the Amsterdam canals, where clever use of multimedia brings the story of the canals to life. The museum was initiated in 2011 by Mr. Gerard Krans, the owner of Transmark.
