Heavy.com, a New York company that runs a Web site focused on 18-34 year old men, said it has raised $20 million in financing from Polaris Venture Partners. This is the second round of funding from Polaris, which provided $10 million to Heavy.com in early 2006.

Here’s a summary of the deal in Adweek, which cites chief executive Simon Assaad saying the money will be used to help Heavy expand into other areas, including a sports site and teen destination. The sports site will launch the next two months, while the teen extension will debut later this year.

He said the sites would follow the Heavy model of mixing original broadband Web programming and user-generated content.

Heavy’s November 2006 audience was 1.9 million uniques, according to Nielsen NetRatings.
