Mike Putman is CEO of Custom Travel Solutions (CTS) and the founder of RouteStack. With 35+ years in travel and four companies behind him, he has watched the industry evolve from storefront agencies to online booking to mobile — and he's now building for what comes next. In 1995, he launched 11thHourVacations.com, one of the first online travel sites. He later led Rovia to the World Travel Award for World's Leading Online Travel Agency, and founded CTS in 2015. RouteStack is his answer to a simple question: when AI agents book travel, what infrastructure do they need?
