About Flagship Pioneering
Flagship Pioneering based in the US, is a private equity firm and established in 2000. Firm that consists primarily of seed and early-stage investments, with some later stage value investments, invests in three principal business sectors: therapeutics; medical technologies; and sustainability/clean technology. The firm generally assembles a syndicate with other leading venture firms as the company matures. Flagship Pioneering, originally called as NewCoGen or New Company Generation and formerly known as Flagship Ventures, operates through two synergistic units: Venture Labs which invents and launches transformative companies, and Venture Capital, which finances and realizes innovative early-stage companies across the US.
