David Bullock
Twenty years building for the web, the last fourteen on Memberium. David founded Web Power & Light in 2006 on the back of a decade in enterprise IT and defense: PKI and smart-card middleware for the Defense Department’s Common Access Card program at Litronic, then VP of Technology at OneCoach. He created Memberium in 2012 because the membership plugins already on the market couldn’t keep up with high-volume sites. In 2014 he brought Micah Mitchell from Castle Mountain onboard to run sales and marketing, and later created Sushi LMS and the WPAL Helpdesk alongside it. Memberium now runs on several thousand active sites and has peaked at 23 million managed users; the largest single customer site served over one million users.
