A123 Systems (NASDAQ: AONE) got its start back in 2001 in Dr. Yet-Ming Chiang's laboratory in MIT. Along with two others -- Gilbert N. Riley, Jr., and Ric Fulop -- he saw a huge opportunity to build new battery technology. While it took six years to hit the market, it was well worth the effort.

Today, A123 launched its IPO (here's a profile on the deal). The company sold 28.1 million shares at $13.50 each. With this slug of capital, A123 can continue to build out its operations and capitalize on the growth opportunities.
