PEM Media Agency has launched Nexos, a first-of-its-kind mobile platform that delivers real-time, location-based offers to Bogotá's 2.5 million daily TransMilenio riders—using ultrasonic tech from LISNR. By transforming everyday commutes into high-value retail touchpoints, Nexos is redefining the intersection of transit and commerce.
BOGOTÁ, Colombia , June 30, 2025 /PRNewswire-PRWeb/ -- PEM Media Agency and LISNR announced the launch of Nexos, a groundbreaking mobile app that delivers real-time promotions to consumers across Bogotá by harnessing LISNR's cutting-edge Radius® ultrasonic technology. Starting today, Nexos will connect directly with TransMilenio, the city's primary Bus Rapid Transit system, to reach more than 2.5 million daily riders in a completely new and seamless way.
By integrating with TransMilenio's existing speaker infrastructure, Nexos leverages LISNR's ultrasonic proximity platform to send location-aware, hyper-relevant promotions to riders while they're waiting at stations or traveling on buses—without relying on Bluetooth, Wi-Fi, or QR codes. The result: a powerful new channel for brands and merchants to engage directly with consumers and transform everyday transit moments into high-impact retail touchpoints.
"Our vision with Nexos is to build a community of savvy, engaged consumers who receive the right offer, at the right place, at the right time," said Jose Cuellar, CEO of PEM. "By combining our relationship with over 250 clients with LISNR's Radius technology, we've created an intelligent ecosystem that benefits riders, merchants, and brands."
LISNR's ultrasonic Radius SDK powers this hyper-targeted engagement by enabling devices to communicate using inaudible sound, providing real-time presence detection without added hardware or network connectivity. Riders who opt in to Nexos simply enable microphone permissions and enjoy a curated stream of deals triggered by their proximity.
Transit and retail are increasingly intertwined, with studies showing that retail sales see a 20% uplift near major transit hubs, and areas within one mile of a transit station experience a 28% increase in new retail businesses. By bringing targeted promotions directly into the commuting journey, Nexos capitalizes on this growing global trend.
"We're proud to support PEM in delivering smarter and more meaningful connections, further integrating retail in transit environments," said Eric Allen, CEO of LISNR. "Nexos is a great example of how proximity-first experiences can unlock value for both consumers and businesses—in one of Latin America's most dynamic cities."
With Nexos, PEM aims to transform daily commutes into engaging, rewarding experiences—while offering merchants and brands an unprecedented tool for context-aware, high-impact advertising.
