Can you share which ones do?
CapOne and Discover business cards report to personal. I don't even think the Discover biz card has been available for years. I'd guess there are others from CUs or smaller banks that report but that's a guess.
I can say with authority that business CC's issued by AMEX, BofA, Barclays, Chase, Citi, FNBO, USBank do not report to personal. A little bird told me BBVA doesn't report, but I've never seen the little bird's credit reports so take that with a grain of salt.
