NewLimit is a company that invents medicines composed of epigenetic reprogramming factors that restore youthful function in old cells. They leverage functional assays, single cell multi-omics, and machine learning to reveal epigenetic features of aging and discover rejuvenating interventions. The company is composed of experts across cell biology, genomics, computational biology, machine learning, and operations. They collaborate across disciplines to design experiments and models that build upon each other. They work iteratively and move quickly to build technologies and generate enabling data. Each experiment informs the next.
However, they have announced that they will start by deeply interrogating epigenetic drivers of aging and developing products that can regenerate tissues to treat specific patient populations.
