Pili is a French bio-technology company whose mission is to develop and produce renewable dyes and pigments for the industry. In 2016 when Pili won the first edition of Circular Challenge, "Pili was struggling to finance the project and it was a time when the company really needed support." according to Jeremy Blache, cofounder. Today Pili continues to optimize its technology, so that its biotechnologies are competitive with the petro-chemical industry and it has a team of 15 scientists to produce wide ranges of dyes accessible to all.
