Investment thesis

The firm believes biology has transitioned from a science to an engineering discipline, enabling precise reading, writing, and editing of life's genetic code at unprecedented scale. Gene technology startups can address many severe and costly diseases, improve quality of life, and reduce healthcare burdens. Additionally, gene tech enables sustainable production of new materials and products through engineered plants and microbes. Lexi targets companies leveraging DNA, RNA, cellular engineering, and omics technologies to create these solutions.
