Yeah, sorry, I have little tolerance for government created monopolies that are overly bureaucratic. We actually did have an SBIR for which we needed it.
D&B seems to be a good company, but the DUNS system seems broken and requires payment just to signup for no value being provided.
What makes you think D&B is a good company? As far as I can tell all their revenue streams sit right on the border of extortion. If they couldn't convince major players like apple or the US Gov to require the usage of a DUNs number, they wouldn't even have those revenue streams.
Additionally they are at this point the number 1 source of voicemail spam for me. And asking them to not call is non-functional.
