Who We Are Osanni Bio is a development-stage therapeutics platform, headquartered in San Francisco, California. We are creative and agile innovators, relentlessly curious about finding new ways to target the biology behind diseases with the greatest unmet need and determined to do something about it. At the center of Osanni is its innovation engine, which is optimized for discovering new scientific insights, designing novel drug concepts, and efficiently advancing programs to a meaningful proof-of-concept. Once a program is sufficiently de-risked, it graduates into its ecosystem of affiliate companies, which are equipped with the dedicated focus, specialized talent and support necessary to scale. Osanni's architecture marries the scientific depth and operational power of a centralized platform with the speed, agility and accountability of independent companies. The result: an opportunity to create and deliver more transformative medicines. We hold patients and the physicians who care for them as our North Star.
