Bridgefy

Bridgefy is a Mexican software company that enables mobile apps to communicate without internet connectivity using Bluetooth mesh networking. Its SDK allows any app to send messages, data, and media between devices within 100 meters, with messages hopping across nearby Bridgefy users to cover larger distances. The technology uses the Signal Protocol for end-to-end encryption and has been widely adopted during protests, natural disasters, large events, and in areas with poor connectivity. Bridgefy's SDK is used by developers globally and the consumer app has been downloaded millions of times. The company was founded in 2014 and is co-headquartered in San Francisco.
