Alex's body of work speaks for itself, but let me just say that he is one of the most extraordinary people I have ever known. His intelligence, his humanity, and his ability to communicate and connect with people are all exemplary. He sets the standard for me as I strive to be a better communicator and a better human. If you have an opportunity to work with Alex or spend time with him, go for it.
I enjoy acting as a technical advisor, as well as connecting young companies with potential partners, hires, and later-stage investors.
