About Cellsense
Cellsense manufactures sustainable products for the fashion, jewelry, and beauty industries utilizing our proprietary material made from Algae and Cellulose. Cellsense aims to replace plastics and resins, and in doing so eliminate major sources of microplastics and heavy metal pollution. With our material, we can achieve a wide range of colors, clarities, forms, and even unique properties such as bio-fluorescence. Our novel manufacturing systems enable us to produce complex beaded textiles at scale, replacing overseas manual labor with highly automated domestic production. Currently, we are focused on scaling up our process while engaging in paid pilots with industry partners. You will join us at an exciting stage of our growth.
