beat out rival credit card issuers because it's the only company to have extended all of the major CARD Act protections to its business-branded cards, said CardHub, a credit card comparison website.

The CARD Act was passed in 2009 ostensibly to protect credit card users from unfair policies. Nonetheless, the law applies only to personal cards rather than business accounts despite the close ties between many small business owners' personal and company finances.

The report covers 19.4 million sole proprietors, 1.4 million corporations and 1.6 million partnerships, which together comprise the total number of non-employer businesses and about 75% of all businesses in the U.S.

The District of Columbia had the highest percent increase in the number of non-employer businesses, an increase of 7.2% in 2011 compared to the year before, followed by North Dakota (up 4.3%), Arizona (up 3.2%) and Delaware (up 2.9%).

Fox Business


Corcoran says she prefers to see entrepreneurs put some skin in the game first before they seek funding.

"Everyone is focused on finding the right angel investors," Corcoran told

Fox Business

. "The right people are themselves, I want to see how much money they can scrape together on their own. The reason is, that is the most valuable money, because you learn how to stretch it. And you will stretch every dollar."
