The Bain Capital team was initially reluctant to invest its capital. By 1985, things were going poorly enough that Romney considered closing the operation, returning investors' money to them, and having the partners go back to their old positions. The partners saw weak spots in so many potential deals that by 1986, very few had been done. At first, Bain Capital focused on venture capital opportunities. One of Bain's earliest and most notable venture investments was in Staples, Inc., the office supply retailer. In 1986, Bain provided $4.5 million to two supermarket executives, Leo Kahn and Thomas G. Stemberg, to open an office supply supermarket in Brighton, Massachusetts. The fast-growing retail chain went public in 1989; by 1996, the company had grown to over 1,100 stores, and as of fiscal year-end January 2012, Staples reached over $20 billion in sales, nearly $1.0B in net income, 87,000 employees, and 2,295 stores. Bain Capital eventually reaped a nearly sevenfold return on its investment, and Romney sat on the Staples board of directors for over a decade. Another very successful investment occurred in 1986 when $1 million was invested in medical equipment maker Calumet Coach, which eventually returned $34 million. A few years later, Bain Capital made an investment in the technology research outfit the Gartner Group, which ended up returning a 16-fold gain.
