Angie’s List, the premium, user-paid directory of local business reviews, announced today that it has raised $18 million in new capital from Lighthouse Capital Partners. The site has now raised $66 million in total, including $13 million in 2006 from Battery Ventures, White River Ventures and Aquent, a Boston-based staffing firm. In 2008, the site raised $35 million in additional funds from Battery.

As part of the new announcement, Angie’s List also disclosed that it has 750,000 members in 124 markets, up from 650,000 this summer. There are typically more than two members per paid subscription, so that number translates into an estimate of roughly 324,000 paying members. Members pay from $10 to $67, depending on various factors, but mostly on the number of reviews in a given market.

Angie’s List Founder and CMO Angie Hicks is a featured speaker at Kelsey’s landmark ILM:08 show this week in Santa Clara. She is speaking on a session alongside ServiceMagic Cofounder Rodney Rice.
