This is a scam.I think that they are trying to get personal information by marketing themselves as people who give out grants.

I *67 and called the number.  They're a service provider who run campaigns for various clients.  I'd normally be skeptical about it, but this one I trust.  If you call the number there is an option to take your number off their list.  Hopefully they will not call again.

Many of those companies that leave voice mail ads, not many have kept their word when I had requested to be taken off their calling list.  They have done that so far and I have not had a call since.

These calling ads really annoy me to no end but at least these guys do take you off their list.  I'll give them that much.

I called back to get them to take me off their list but I learned so much more about what's out there for small businesses in terms of funding options through government programs.  I also dug around to find out more about them and they've been around for over 10 years without any problems or major complaints.  

Cheers!
