I may have a few gray hairs, but I'm a digital tech entrepreneur from the earliest days. My companies helped make online healthcare understandable, banking simple and data insightful. There have been my fair share of entrepreneurial mistakes. But I've also sold tens of millions of digital work, enjoyed a Fortune 500 exit, lived through acquisitions, landed National Science Foundation grants, published patents and even won a SXSW award. I'm not quite finished.
