Guillaume Wegria

Guillaume co-founded Fyteko in 2014 alongside Dr. Juan Carlos Cabrera and Benedicte O'Sullivan. The company has developed a proprietary enzymatic synthesis technology using biosourced molecules to create biostimulants, herbicide enhancers, and biopesticides. Key products include Nurspray, Nurseed, and Nursoil, all targeting abiotic stress in crops.

In early 2025 Fyteko closed a EUR 13 million Series B round to scale its operations and accelerate commercial expansion. Guillaume's story was also profiled by Innoviris, the Brussels research and innovation agency.
