Company: San Francisco 49ers

Every season, the San Francisco 49ers brings on a handful of rookies to try to make a name for themselves. But last year saw a spike in hiring for the program -- CEO Jed York added about 1,000 construction jobs to complete the football team's brand new Santa Clara Stadium.

The project, which will move the 49ers from the iconic Candlestick Park in San Francisco, should wrap up in 2014 and cost over a billion dollars. The new stadium will be tricked out with bigger, better screens, Wi-Fi throughout, and fewer seats, but more total square footage and fancy club seats.

Besides construction, York says he hired 60 other people last year and will add 10 more full-time employees in the year to come. York took over the team in 2008 at the age of 27.
