Four-time Super Bowl champion Joe Montana wasn’t looking to be an investor after his NFL career, but his San Francisco 49ers teammates convinced him to give it a shot.

In an interview with CNBC on Thursday, the legendary quarterback recalled how former offensive tackle Harris Barton and former safety Ronnie Lott approached him with an idea to start a “fund of funds.”

“And because we lived around all the guys who were running Sequoia, Kleiner, Excel, all the top-tier funds, we’re going to leverage our friendships into access,” Montana said.

Silicon Valley and the NFL are converging again on Sunday as the Super Bowl will be played in San Jose, where the 49ers now play their home games.

Back when Montana first got into investing, he and his associates initially raised $15 million, and the fund grew from there, helping them get into leveraged buyout funds, hedge funds, and real estate funds, he said.
