Cortera can be thought of as a Yelp for business credit, offering reviews on large and small businesses alike that have been submitted by the community. In other words, it can help you figure out if a company you’re thinking of dealing with is going to pay you in a timely fashion, or if it’s run by deadbeats who should be avoided.

Up until now, the business credit market has been dominated by one major player: Dun & Bradstreet. But Cortera says that D&B fails to properly address small businesses, which account for a large percentage of America’s GDP. So Cortera has built out a database that includes not just the large companies that are D&B’s bread-and-butter, but also countless smaller ones that previously have been neglected.

The site’s members can use a review system much like the ones you’ll find on Yelp and Amazon to share their experiences with companies on the site, and paid members can also see key data like a company’s annual spending budget and supplier volume. Cortera offers one-off reports for as little as $3, and also has monthly plans beginning at $29 a month.

Cortera (formerly eCredit) makes Quicklook, a service that provides information relevant to credit analysis, and TREE, a navigational tool that visually represents a company’s organization. Cortera has created a comprehensive database of nearly every company in the United States, with related analytics for each.

Fidelity Ventures acquired Cortera in 2006, and along with Battery, has provided $11 million in growth capital.
