Zac King is a fractional go-to-market leader who partners with growth-stage B2B companies ($5M–$30M) to build AI-powered GTM engines and transition from founder-led sales to scalable, repeatable revenue systems. Working embedded within teams, he designs and implements core sales infrastructure—including ICP definition, outbound automation, CRM architecture, lead scoring, and sales playbooks—typically within a focused 90-day execution framework. Prior to his fractional work, Zac founded a VC-backed AI platform in the healthcare space, and earlier led technology commercialization at the University of Sydney, closing deep tech deals with corporates and investors up to $140M in medtech. He also held leadership roles at MediaMath, where he managed distributed global sales teams and consistently closed complex enterprise AI/ML deals ranging from $1–2M up to ~$25M. Based in Noosa, Australia, Zac brings a pragmatic, execution-first approach to GTM—and, as a fun fact, is formally trained in bear awareness and avoidance from his time working in Canada’s Northwest Territories.
