LISNR® is a pioneer in proximity-based engagement. For over a decade, we’ve been helping merchants securely recognize, interact with, and transact with their customers—seamlessly bridging the gap between digital and physical experiences.
Where We Started
Built on Sound, Designed for Scale
Founded in 2012, LISNR introduced Radius®, its ultrasonic SDK, as a breakthrough in secure, hardware-free proximity verification. LISNR was built on the idea that sound is the most accessible and secure way to transmit data.
Originally designed as a software-based alternative to NFC, Bluetooth, and QR codes, Radius quickly became the industry standard for frictionless proximity authentication and contactless transactions. LISNR holds the largest IP portfolio in the industry, with 131 total patents (6X more than the peer average). Today, LISNR has evolved beyond a single product, building a broader ecosystem of applications across retail, mobility, finance, education, and live events.
Why Proximity Solutions Matter
Connecting Businesses & Consumers in Real Time
LISNR is taking a leadership role in the rapidly expanding Proximity Engagement market, which is projected to grow from $64 billion today to $280–$360 billion by 2030. As businesses seek more intelligent, dynamic, and personalized interactions, they turn to LISNR as the infrastructure layer to power their full suite of proximity-driven solutions.
Radius SDK remains the foundation—an ultrasonic technology layer that powers seamless, secure proximity interactions. Alongside Radius, Quest, LISNR’s newly integrated engagement platform through its acquisition of Arden Labs, enables businesses to activate consumer intent through gamification, personalized offers, and meaningful rewards.
Our applications span the whole customer journey, from in-home and in-transit to in-store, allowing merchants and brands to turn micro-moments into meaningful touchpoints.
Where We're Headed
The Future of Proximity-Based Engagement
Every consumer interaction is an opportunity to unlock something of enduring value for the customer and the merchant.
Digital solutions and products have more data than ever, but need a way to connect it to physical spaces and consumers. By merging the data from the digital world and context from the physical world, LISNR is at the intersection of solving the biggest problems in retail media, broadcast engagement, and AI assistants.
LISNR’s major investors include Visa, Intel, Jump Capital, Mercury Fund, R/GA, and Synchrony Financial. Since our inception in 2012, LISNR® has raised over $43M and pioneered many advancements in ultrasonic technology, ultimately driving its usage in payments and identification around the world today.
