Isilon spokesman Jay Wampold said it was fairly standard for venture capitalists to get on the boards of early-stage companies that they fund and then leave as the company matures. Isilon had a $109 million public offering in December.
McIlwain is a managing director at Madrona Venture Group, an early investor that owns about 16 percent of Isilon shares.
Isilon announced a customer win yesterday. The company will provide storage for NBC Universal’s media programming, including television shows, movies and news. NBC Universal will also use Isilon when it covers the 2008 Olympic Games.
