Wentao Xiao is a founder and growth operator with nine years of experience building performance marketing businesses and ad-ops automation. He co-founded CACTIVATE to help startups and SMBs maximize ROAS and now leads AgentMark, which builds AI agents to run ad ops 24/7 at a fraction of hiring cost. His background spans hands-on bootstrapping—from operating a million-dollar Airbnb portfolio with 99.5% occupancy to leading product experiments at Zealery—giving him a practical sense for scalable operations and unit economics. As a former Global Entrepreneur in Residence at Babson, he mentors founders and connects startups to the Boston entrepreneurial ecosystem. Wentao’s uncommon blend of creative hustle and systems thinking shows up in solving the nitty-gritty bottlenecks (QA, pacing, ad ops) that most strategies miss. He’s driven by a builder’s mindset—“Stay hungry. Stay foolish”—and applies it to automating repeatable operational work.
