Announces Strategic Additions to Team and Opening of West Coast Office

BOSTON & SAN FRANCISCO--(BUSINESS WIRE)--Third Rock Ventures, L.L.C, a venture capital firm focused on building life sciences companies, today announced the final closing of Fund II, raising $426 million in an oversubscribed fund.

"We are grateful for the strong support for our model and the significant interest from our existing and new investors," said Kevin Starr, partner of Third Rock Ventures. "In 2007, we founded Third Rock with a $378 million Fund I, which enabled us to successfully seed, support or launch more than 15 life sciences companies. These companies were formed around disruptive areas of science and medicine and many were developed as part of Third Rock's unique company discovery process. We look forward to continuing to partner with entrepreneurs, researchers and company founders to pursue bold ideas and groundbreaking science that promise to dramatically improve the lives of patients."
