Initially, Bain Capital focused on venture capital investments. Romney set up a system in which any partner could veto one of these potential opportunities, and he personally saw so many weaknesses that few venture capital investments were approved in the initial two years. The firm's first significant success was a 1986 investment to help start Staples Inc., after founder Thomas G. Stemberg convinced Romney of the market size for office supplies and Romney convinced others; Bain Capital eventually reaped a nearly sevenfold return on its investment, and Romney sat on the Staples board of directors for over a decade.
