In 1987, Lee Rosen founded Trams with a vision to revolutionize the travel distribution industry. Over two decades, Trams became a trusted name, offering robust systems that connected various facets of travel agencies, from marketing consortia to booking engines. After a hiatus beginning in 2009, Rosen returned with renewed vigor, recognizing the evolving landscape of travel technology. This led to the birth of Tres Technologies, a company built upon the rich legacy of Trams but designed for the modern era. In April 2021, Tres Technologies reacquired Trams from Sabre, marking a new chapter in delivering integrated solutions for travel agencies.
