PLAiR’s core product is a dolphin-fin-shaped USB dongle that plugs into a TV and, once connected to Wi-Fi via a companion mobile app, lets users send photos and videos from computers, tablets, or phones directly to the big screen. Priced in the $59–$79 range, the device seeks to differentiate itself from Apple TV and Roku by allowing playback of almost any online or mobile content rather than being limited to pre-approved apps. PLAiR supports iOS and Android apps as well as browser extensions for creating and managing video playlists, and multiple dongles can be linked to beam content to several TVs simultaneously. The company has raised $2.1 million to finance the product’s rollout. While specific revenue, user numbers, founding date, and location were not disclosed, the firm is positioning its affordable, platform-agnostic hardware as an alternative to Apple’s AirPlay ecosystem and other set-top streaming solutions.
