I attended their open house, and I didn't get the impression they are just early stage angels, although if thats all they are that would still be great, because there are very few of those here. Many in the investment community in the southeast have been openly hostile towards the need for more early stage capital, let alone willing to fund seed stage companies.
Anyway, my impression from talking with the Shotput guys was that there was a lot of value add they were providing. I would suggest actually contacting them if you are interested, as I think you'll be surprised and impressed. Most of these guys are active advocates for our region's startups and do everything they can to mentor and open doors.
