This year, the jury received 324 sustainable business plans from 57 different countries. The jury will award the €500,000 grand prize – intended to help the winner get his or her product to market within two years – at the finale, taking place in Amsterdam, the Netherlands. A runner-up prize of €200,000 is available for one or two other promising finalists.

Devin Malone is the co-founder of One Nights Tent, a company which produces recyclable tents. Users pre-purchase their gear online and receive it right on the festival campsite. Afterwards One Nights Tent recycles or composts anything left behind.

Turbosail (France): Pierre-Yves Cousteau
Pierre-Yves Cousteau is the co-founder of Turbosail™. This company develops an efficient wind propulsion technology for seagoing vessel operators, which is proven to deliver a 30% average reduction in fuel consumption as prototype.
