Company Description

Formation Bio is a technology-driven pharmaceutical company that acquires clinical-stage drugs and uses proprietary artificial intelligence platforms to manage their development. The company's current activities focus on optimizing aspects of clinical trials, including their design, completion speed, and the quality of the data collected. An example of its work is the development of LNK01006, a TYK2 inhibitor, which is being advanced through its subsidiary, Bleecker Bio. Founded in 2013 and previously known as Trialspark, the company was established by Benjamine Liu, who serves as CEO, and Linhao Zhang, the COO.

Looking forward, Formation Bio plans to continue acquiring clinical-stage assets and expanding its development pipeline. A Phase 1 study for LNK01006 is scheduled for the first half of 2026. The company has recently made several announcements, including the closing of a $372 million Series D funding round in July 2024 and the opening of a new office in Boston. It also launched ARK, a platform designed to connect data and AI tools across the organization. In 2024 and 2025, the company received recognition through several industry awards, including the 2025 CNBC Disruptor 50, the 2025 Fierce 15 Award, and the 2024 Endpoints 11 Award.
