Vendasta
Scaling a SaaS Platform to Global Reach
Before AdCellerant, George spent ten years at Vendasta in senior executive roles, including Chief Customer Officer and EVP of Sales. During that time, he built and led large customer-facing teams and helped architect Vendasta’s go-to-market strategy as the company scaled rapidly.
Under George’s leadership, Vendasta grew from a small SaaS startup into a global platform serving tens of thousands of agencies and small businesses. His work at Vendasta centered on empowering local businesses with enterprise-level digital tools, long before “AI-driven marketing” became an industry standard.
