Dunn & Brandstreet. They want you to pay to either clean your business credit (they don't do personal credit) or buy some sort of business credit protection plan. It is like paying protection money to the mob, or paying to remove bad reviews on yelp.  They will try to scare you into purchasing their products. The bottom line is that in small business today, your business credit runs off the back of your personal credit, no bank or CC company gives credit without requiring a personal guarantee at which point it is based on your personal credit. For medium and large size companies doing more NET30 terms where the folks extending credit may be seeking credit insurance against a chance of your default, these guy might come into play.
