I would highly recommend Charlie as an investor/advisor because his guidance has played an critical part in our successes thus far. He is exceptionally well-rounded with strong backgrounds in business development, venture capital and technology. Also, if I ever need a dose of cold truth, I turn to Charlie! (don't expect any sugarcoating).
A great guy that goes beyond the first layer of questions to really understand what you're doing and how to help. I look forward to future engagements and recommend the same for anyone passionate about their work!
