The restaurant industry is currently going through a major labor shortage. This situation will only worsen if there is an economic downturn, especially for quick service restaurants. Presto is the leader in next-gen automation technologies that help restaurants increase capacity, lower costs, and enhance guest experience by significantly improving labor productivity. We are experiencing rapid growth and are on our way to be publicly listed in September, 2022. Our solutions include:

● Voice: Guests and staff can place orders using conversational A.I. with over 95% accuracy (highest in the industry), even in noisy environments.

● Vision:  Using just a few cameras equipped with computer vision, restaurants can measure throughput and order accuracy, identify issues, repeat visitors and implement real-time fixes.

● Touch: Designed for both drive-thru and dine-in applications, the same Presto Flex can be deployed as a pay-at-table, staff handheld, kiosk, or drive-thru line buster—offering wide front-of-house flexibility.

Join us to be a part of a phenomenon that is revolutionizing the restaurant industry!
