Biosimo

Biosimo replaces fossil-based chemicals with bio-based alternatives at petrochemical economics — no bio-premium at scale, up to carbon-negative with certain feedstocks. Our proprietary catalyst converts bioethanol into acetic acid, acetyls, acetone, and adjacent molecules in a single step on standard industrial equipment with over 8,000 hours of catalyst stability. We have 6 paying customers across pharma, cosmetics, adhesives, and energy, a $400M+ distribution MOU with a global partner, and a top-2 global acetyls producer pilot testing our product. The platform addresses a $70B market where less than 3% is bio-based today. Asset-light model — IP and catalyst in-house, manufacturing outsourced to partners. ETH Zurich spin-off. Activate Fellow 2025. Houston and Zurich. Venture-backed.
