Seattle Genetics was incorporated in 1997, with its headquarters in Bothell, Washington, north of Seattle.

Clay Siegall relocated to Seattle to work for Bristol Myer’s, however, the company decided to shut down its Seattle operations. Driven by passion and vision, Siegall looked at this an opportunity to start his own company that would specialize in the research and development of ADC’s. Siegall co-founded Seattle Genetics to help people fight their battle with cancer.

In 1998, USD 7 million was raised through venture capitalists for research at Seattle Genetics. An additional USD 30 million was raised 9 months later, again through VC funding . The company went public in 2001 and raised USD 51 million.
