The founders of Helsieni do not understand the word ‘waste‘. Their grey brain cells have a disorder that always turns this word into ‘mushroom‘. This could be considered as a handicap, but they decided to see it as an opportunity. Thus Helsieni was born, with a core mission of cultivating mushrooms on what others call ‘waste’ (used coffee grounds, agro-industrial byproducts, or other un-utilized nutrient streams).
Helsieni does not build big factories. We believe that people should learn how to produce mushrooms at home, from their own coffee grounds. For that purpose, Helsieni provides people and companies with highly efficient low-tech solutions.
When he is not busy tasting Chris’ yummy lunches, Stéphane is a loud mushroom engineer, an organic electrical grower, an enthusiastic chicken saxophonist as well as a happy jazz farmer.
