About Hexagon Bio:

Hexagon Bio leverages a genomics-based platform and understanding of natural product evolution to develop next-generation medicines for human disease. Hexagon Bio's algorithms identify gene clusters that encode the machinery needed to produce specialized metabolites that can be harnessed against human disease targets. Our unique platform allows us to produce new chemical leads based on these findings. We use data science, genomics, synthetic biology, and automation to discover potent, evolutionarily refined small molecules and their cognate targets from fungal genomes, and apply medicinal chemistry when needed to optimize these molecules into truly transformative medicines.

Location: Menlo Park, California
