Princeton Consultants is an information technology and management consulting firm in Princeton, New Jersey, with a second office in New York City. Its oldest practice is mathematical optimization, and its AI work is sold inside that: it describes combining AI, optimization, software development and management consulting in a single engagement, and lists model review and quality assurance among its services. It is an IBM partner and exhibits at the INFORMS analytics conferences, which is where most of what is known here comes from. Its own listings give conflicting founding years in 1980 and 1981, so neither is recorded, and the website on this record comes from a single partner directory entry rather than from the firm.
