Summary
👤
SeniorGuy Mckenzie is a serial founder and technology entrepreneur with over three decades of experience building data-driven SaaS businesses for healthcare and specialty industries. As co-founder and CEO of PharmaData he helped scale a two-person startup into a global, award-winning platform used by 10,000+ users, and he now applies that same product-first approach to medicinal cannabis platforms (MediStack, Code4 Cannabis, ScriptPad) that have onboarded tens of thousands of patients in months. He blends hands-on backend engineering—contributing bug fixes and features to Apache Drill around HDFS reading and JSON handling—with strategic product direction, partnerships and team building. Notably, he pairs high-tech ventures with sustainable agribusiness: a 500-acre truffière and a premium Aussie White sheep breeding program that reflect his appetite for long-term, quality-first projects. With deep ties across Australia, Europe and Japan, Guy is skilled at turning complex regulated workflows into elegant, integrated digital ecosystems.
