goTenna (goTenna Inc.) is a Brooklyn, New York-based startup that designs and develops technologies for off-grid and decentralized communications. goTenna devices pair with smartphones and, through intelligent mobile ad hoc networking protocols, enable users to send texts and share locations on a peer-to-peer basis, foregoing the need for centralized communications infrastructure of any kind. goTenna was founded by siblings Daniela and Jorge Perdomo in November 2012 after Hurricane Sandy knocked out 25 percent of cell towers, and caused outages for 25 percent of Internet services, across 10 states on the East Coast. The company’s stated goal is to build “people-powered peer-to-peer communication systems…reducing our reliance on cell towers and wifi routers, and providing anyone the ability to create a network on their terms.” goTenna’s first prototype was built out of hardware hackerspace NYC Resistor. The company was bootstrapped until it raised a seed round of venture capital late in 2013. The company started taking pre-orders for its first product in July 2014. These orders started shipping in October 2015. In March 2016, goTenna closed a $7.5MM Series A financing and started to sell its product in retail channels beyond its own website.
