LISNR is a Cincinnati-based technology company pioneering ultrasonic data-over-sound technology for proximity verification and contactless interactions. Its core product, the Radius SDK, enables secure, hardware-free data transmission via device speakers and microphones, serving sectors like retail, mobility, finance, payments, education, and live events[1][2][3][5]. LISNR solves the problem of bridging digital and physical experiences by replacing NFC, Bluetooth, QR codes, and Wi-Fi with low-power, scalable audio-based solutions that enhance efficiency, security, and personalization—such as frictionless payments, transit fare collection, and in-store offers[1][2][4]. The company powers applications for Fortune 100 partners, including a recent partnership with S-CUBE for ultrasonic transit systems in India, and has grown its ecosystem through the Quest engagement platform (via Arden Labs acquisition), with revenue at $5.3 million and 37 employees[1][2].
Founded in 2012, LISNR emerged from the insight that sound offers the most accessible and secure method for data transmission, initially as a software alternative to NFC and other hardware-dependent tech[2]. The founders developed Radius—originally Smart Tones—in response to the need for frictionless proximity authentication, quickly establishing it as an industry standard with early adoption in contactless transactions[2][5]. Pivotal moments include amassing the largest IP portfolio in ultrasonic tech (131 patents, 6X the peer average) and evolving beyond Radius to a full ecosystem, including the Quest platform for gamified engagement, while partnering with global leaders in mobility and finance[2][4].
LISNR rides the proximity engagement wave, projected to expand from $64 billion to $280–$360 billion by 2030, fueled by demand for real-time, personalized interactions in a post-pandemic world prioritizing contactless tech[2]. Timing aligns with shifts away from power-hungry wireless standards toward audio-based solutions that leverage ubiquitous speakers/microphones, reducing costs and barriers for merchants in retail, mobility, and finance[1][4][5]. Market forces like rising e-commerce-physical blends and secure P2P payments favor LISNR, influencing the ecosystem by setting ultrasonic standards and enabling micro-moment monetization for brands[2][3].
LISNR is poised to dominate proximity infrastructure as adoption accelerates in high-volume sectors like transit and retail, with Quest driving engagement revenue amid AI-personalization trends[2][4]. Expect deeper integrations in emerging markets (e.g., India expansions) and payload enhancements via multi-channel tech, potentially capturing significant share in the $300B+ market by leveraging its unmatched patents[1][2][5]. As businesses prioritize seamless digital-physical fusion, LISNR's audio edge will evolve from verification tool to full-stack platform, solidifying its role as the ultrasonic standard for tomorrow's touchpoints—echoing its founding vision of sound as the ultimate connector[2].
LISNR has raised $30.9M across 4 funding rounds. Most recently, it raised $16.0M Series C in May 2019.
