Third Rock Ventures Promotes David Kaufman, M.D., Ph.D., to Partner

BOSTON–(BUSINESS WIRE)–Third Rock Ventures announced today that David Kaufman, M.D., Ph.D. has been promoted to partner. Dr. Kaufman joined Third Rock as a venture partner in 2020 and has made significant contributions to the firm’s discovery and company creation efforts. As a physician-scientist with prior tenures at the Gates Medical Research Institute and Merck Research Labs, he brings a unique and important perspective to the team. 

“Our hands-on approach to creating companies is predicated on individuals who possess a passion for science and an unwavering commitment to improving health outcomes through biomedical innovation,” said Reid Huber, Ph.D., partner at Third Rock. “Since joining our team in 2020, David has made numerous contributions within our firm and across our portfolio of companies. His unique combination of public health and translational medicine expertise add considerable value to our partnership, and we look forward to leveraging these talents to harness the unprecedented levels of innovation present in our industry today.”

“I am very excited about my new role at Third Rock,” said Dr. Kaufman. “In my time with the firm to date, I have learned a great deal from this team of exceptional colleagues who thrive on collaborating with each other to chart the course for the creation of innovative biotechnology companies. I have tremendous appreciation for the approach at Third Rock, which combines science, strategy, business and medicine to translate scientific innovations to novel medicines for patients.”

Third Rock also announced today that it has added two industry leaders as venture partners:

– Jigar Raythatha has joined Third Rock as a venture partner after holding several senior strategic roles at some of the firm’s portfolio companies. Most recently, he was CEO of Constellation Pharmaceuticals, where he led the company through an IPO and its recent acquisition by MorphoSys AG. Under Mr. Raythatha’s leadership, Constellation made important advancements with its pipeline of epigenetic programs in hematology-oncology, which were seen as a value driver for MorphoSys AG. He had originally joined Constellation shortly after its founding as head of corporate development. He then joined Jounce Therapeutics as its chief business officer, and one of its first employees, before returning to Constellation as CEO.

– Jeff Walsh joins the firm with over 30 years of operating experience. He was most recently at bluebird bio where he held the roles of chief operating officer and chief financial and strategy officer. As one of the early employees of bluebird, he was instrumental in growing the company to a global commercial entity with multiple approved products. Mr. Walsh led bluebird’s IPO in 2013 and subsequent equity financings. He drove the foundational strategic partnership with Celgene/Bristol Myers Squibb in cancer cell therapy, ultimately leading to the approval of Abecma for the treatment of multiple myeloma.

Mr. Raythatha and Mr. Walsh join a robust team of venture partners at the firm, including Mark Angelino, Ph.D., Andrea van Elsas, Ph.D., and Lorence Kim, M.D., who each joined in recent months.

“The role of venture partner is an incredibly important and valued one at Third Rock,” said Abbie Celniker, Ph.D., partner at Third Rock. “We are constantly looking to identify key individuals with profiles in critical areas of expertise – strategic, scientific, financial and operational. These individuals are integral in the discovery and creation of our portfolio companies, often taking on interim leadership roles in the early days. With Jeff and Jigar, we have seen first-hand the positive impact they have had in our portfolio. They both bring extensive operating expertise and strategic acumen, and we are looking forward to the contributions they will make as we continue to translate exciting new science to build sustainable companies.”
