uBEAM

uBeam was an ultrasonic wireless power startup founded in 2011 by Meredith Perry and headquartered in Marina del Rey, California. It raised roughly $26 million from Andreessen Horowitz, Upfront Ventures, Founders Fund, Mark Cuban, and Marissa Mayer to charge devices over the air using 45-75 kHz phased-array ultrasound. The company rebranded as SonicEnergy in December 2018 and went defunct on February 5, 2024, without shipping a commercial product. It published no developer APIs, SDKs, or documentation, and both ubeam.com and sonicenergy.com are now parked domains.

uBEAM is profiled on the APIs.io network. Tagged areas include Company, Wireless Charging, Ultrasound, Hardware, and Consumer Electronics.
