Fast Company, in partnership with the Women Presidents' Organization, is looking for the top 25 women business owners in the U.S. and Canada who are changing the rules in the world of business.

These elite entrepreneurs are creating their own companies, their own business models, and their own ways of working -- redefining the way we will all think about business in the future. Our "25 Women Who Are Changing the Game" awards list will be published in the May 2005 issue of Fast Company magazine, and the winners will be recognized at the annual WPO conference to be held in April 2005 in Toronto.

Fast Company is no longer accepting applications. Be sure to read the May 2005 issue to learn who made the list!
