Joseph "Joe" Montana, co-founder of iMFL and retired National Football League (NFL) quarterback, speaks during an interview in San Francisco, California, U.S. on Tuesday, April 30, 2013.

Joe Montana won his first Super Bowl as an NFL quarterback in 1982. Almost four decades later, he's about to get his first IPO as a venture capitalist.

Montana, who led the San Francisco 49ers to four Super Bowl victories and was inducted into the National Football League Hall of Fame in 2000, has spent the past six years investing in start-ups through his firm, Liquid 2 Ventures. He started with a $28 million fund, and is now closing his third fund that's almost three times bigger.
