About Coat-X

Coat-X’s proprietary technology platform originated 10 years ago from a collaboration between the pharmaceutical company Johnson & Johnson with the Engineering School HE-ARC, Neuchâtel.

Back then, a research program was initiated to protect a smart implantable system for the brain. Thanks to this initial partnership and further development conducted by Andreas Hogg during his Ph.D. work, a new conformal coating platform has been developed.

The technology is unique for its superior hermeticity and minimal volume utilization while keeping costs at a competitive level.

Who we are

To commercialize the technology developed by Andreas Hogg (CEO), a team of engineers and professionals has been assembled. 

The team is composed of former Johnson & Johnson colleagues, Asun Rubio (Quality Manager), Yanik Tardy (COO) and Eric Nagels (CFO) ; experts in thin-film coating and reactor design, Jérôme Steinhauser, Ulrich Kroll and Jose Navarro; and an experienced production manager from the watch industry, Hervé Le Dréo.
