Great Place-to-Work

Sponsh is also strongly convinced that sustainability should be part of the company DNA and should be reflected in every business aspect. For example:

  • All CO2 emissions from travel and office are already offset through Trees For All.
  • A Sponsh Foundation has been set up. Part of Sponsh’s future profits will go to this separate, non-profit organization to meet the growing challenge of water scarcity worldwide.
  • Sponsh employees promise transparency, fairness and respect for others
  • We believe in a healthy work-life balance and employee well-being. All our (future) employees are offered a share plan in the form of Stock Appreciation Rights (SARs).

Sponsh was founded in 2018 and consists of the Sponsh holding BV and the operating company Sponsh Water Systems BV, both incorporated under Dutch law. Sponsh is located at Eindhoven University of Technology (TUe), where it has access to the high tech TUe laboratories.
