Danny Manu grew up in Ghana, later built a career in Britain, and became fascinated by a problem that millions of travelers face: how can two people understand each other when they do not share a language?
He developed Click, a pair of wireless earbuds designed to provide live translation across dozens of languages. The system was promoted as capable of translating conversations without requiring the users to remain connected to the internet, an important feature for travelers facing roaming charges, weak signals, or remote locations.
