We are a startup with a passion for nature and water. We are fond of Bionica or Blue Economy thinking, which means looking at nature to find solutions.

The idea for Sponsh started while traveling with a camper through Portugal in summer. The country was experiencing its worst drought in years. It had not rained for several months, the land was yellow and the water reservoirs at their lowest ever. Still, every morning our gear outside was soaking wet. Remembering one of the ideas in Blue Economy, we got into contact with Eindhoven University of Technology. They had recently done an amazing bionica invention in water absorption from the air. We decided to work together to scale-up this material and make it into a product available for everyone.
