The annual Innoventure Conference in Greenville, SC is being held March 25 and 26.
I attended Innoventure a few years ago. Although it was heavily geared towards South Carolina at the time, it was a useful conference with a lot of buzz. They draw entrepreneurs, VCs, corporations, and universities all together. The conference has continued to grow each year and we have had a handful of ATDC and Georgia companies present in the VC forums. It is only a short drive up I-85 from Atlanta so if you are an early stage company looking for money, it is worth looking into.
