Rubi is pioneering the next era of manufacturing with its proprietary enzyme cascade technology. Our cell-free biocatalysis platform converts waste carbon into high-value materials – including cellulose textiles, chemicals, and polymer ingredients – requiring a fraction of the energy use and capital investment of traditional manufacturing systems. Our modular production systems are designed to be deployed anywhere, enabling us to establish resilient and decarbonized supply chains at projected cost parity with existing products. We've established partnerships with global manufacturers and retailers including Walmart, H&amp;M, and Patagonia, and have been honored as World Economic Forum Technology Pioneers, MIT Tech Review 35 Innovators Under 35, European Patent Office Young Inventors Prize winners, and H&amp;M Global Change Award winners. As Rubi continues to scale, we're building an exceptional team across scientific and technical disciplines.
