Mezi will become a wholly-owned subsidiary of American Express. Its technology is already powering AskAmex, a personal concierge app for cardholders that launched its pilot program last year. Mezi users send requests for flights, hotels and restaurant reservations through the app’s SMS-like interface. Mezi then makes suggestions and, once it figures out what users want to do, forwards requests to human assistants to finalize bookings. Founded in 2015 as a personal shopping chatbot, Mezi builds its own deep learning and natural language processing systems instead of using services by IBM Watson and other providers. Its co-founders, CEO Swapnil Shinde and his twin brother, CTO Snehal Shinde, previously launched Indian streaming music service Dhingana, which was acquired by Rdio in 2014.
