Investment thesis
Thayer invests in technology companies serving the travel industry, viewing travel broadly as how and why people move and where they choose to live. It backs both horizontal platforms—payments, cybersecurity, and workforce management—and vertical solutions across loyalty, distribution, and core operating systems. Investing on behalf of travel-industry corporations, executives, and operators, the firm supports both industry outsiders and seasoned operators, connecting founders to partners across hotels, transportation, airlines, cruise, agencies, restaurants, events, sports, entertainment, and experiences.
