Biosolutions for destruction of persistent pollution

Swiss Startup - CellX Biosolutions Main Image

CellX Biosolutions develops high-performance bacterial solutions to destroy persistent industrial pollutants such as PFAS, the “forever chemicals.” Current disposal methods are costly, energy-intensive, and environmentally harmful, with no scalable solution for true destruction. We leverage proprietary microfluidic technology to discover and assemble powerful bacterial consortia for efficient pollutant degradation.

CellX was founded by Dr. Estelle Clerc (CEO), Dr. Fabienne Kurt (CSO), and Geoffrey Besnier (COO), combining deep expertise in microbiology, analytics, and operations. Together, they are building scalable solutions for a $30B+ treatment market driven by tightening regulations.
