Modern Synthesis

Seed Round in 2022
Modern Synthesis is bringing life to new materials by working with bacteria to commercially develop a new class of biobased textiles which offer: (1) Performance without plastics or harsh chemicals: Materials which achieve strength and durability without petrochemical binders, harmful chemistries or toxic byproducts. (2) Aesthetics without animals: A versatile process that unlocks a wide range of looks, feels, and functions to meet designers’ seasonal needs with zero animal inputs. (3) Scale without starting from scratch: A process that leverages abundant raw materials and is designed to integrate with existing manufacturing infrastructure. Modern Synthesis’ technology leverages the intrinsic versatility of bacterial nanocellulose, which is nature’s finest and strongest form of cellulose. Their process not only displaces animal leathers, plastic-based synthetics and other nonwoven textiles, but also generate entirely new possibilities for designers.
