John has held senior executive roles at Adobe Systems, and Sun Microsystems and has been working in Silicon Valley for more than 25 years. He's served on the executive management teams of large, publicly held companies, served on start-up boards, and initiated numerous new ventures in mobile, SaaS and social enablement. Most of the latter were initiated as small skunkworks projects that eventually found their way to shipping commercially-available products and services. He dyes his hair gray as a cover for his youthful energy in business, and to confuse younger, would-be opponents on the basketball court.
