About Willow Biosciences 

Headquartered in Calgary, Alberta, Willow Biosciences is a biotechnology company focused on revolutionizing the industrial manufacturing of active pharmaceutical ingredients and other high-value products traditionally derived from plants. Willow Biosciences has an established integration of cutting-edge basic research and state-of-the-art applied technology development, linking genomics-based plant gene discovery to synthetic biology-enabled microbial strain engineering. Proven success in the development of yeast strains producing pharmaceutical opiates is now being leveraged to establish industry-leading yeast strains engineered to make cannabinoids. Fermentation-based biosynthesis in microbes yields the highest-grade product for industrial and pharmaceutical applications, and provides a distinct value proposition to pharmaceutical partners. It also has the potential for higher product yields at a lower cost compared with extraction and purification from cultivated plants.
