GoTenna is a pocket-sized device that promises to let you communicate anywhere, regardless of the availability of WiFi and cell phone service The goTenna device pairs up with your phone to let you communicate by sending messages over radiowaves.
Cofounders Daniela and Jorge Perdomo came up with the idea for goTenna in the wake of Hurricane Sandy in October 2012. Months later, Daniela had created physical prototypes for a gadget to help people communicate even when they don’t have cell phone service. GoTenna has raised $1.8 million in seed funding.
