Problem
Businesses struggle to deliver personalized, context-aware customer experiences at physical touchpoints because traditional proximity technologies like Bluetooth, NFC, and QR codes have significant limitations, including connectivity dependencies, friction in the user journey, and barriers such as app downloads and location permissions.
Solution
LISNR provides an ultrasonic proximity platform that enables contactless engagement across the entire customer journey—at home, in transit, and in store. The company's Radius SDK uses ultrasonic data-over-audio to transmit information between speakers and microphones, enabling real-time proximity detection and secure access without requiring internet connectivity, Bluetooth, NFC, or QR codes. The Quest customer engagement platform builds on this foundation by offering gamified loyalty programs, personalized promotions, marketing attribution, and secure offline payments. Together, these products allow brands to identify customers at point of entry rather than point of payment, deliver targeted offers at decision points, and unify consumer behavior data across the full journey.
Target Audience
Primary customers are retailers, financial institutions, mobility/transit operators, and education technology providers seeking proximity-based customer engagement, secure authentication, and loyalty solutions across physical and digital touchpoints.
