Bridgefy is a Mexican software company with offices in Mexico[1] and California, the United States, dedicated to developing mesh-networking technology for mobile apps.

It was founded circa 2014 by Jorge Rios, Roberto Betancourt and Diego Garcia who conceived the idea while participating in a tech competition called StartupBus.

[8] The app gained popularity as a communication tactic during the 2019–2020 Hong Kong protests and Citizenship Amendment Act protests in India,[9] because it requires people who want to intercept the message to be physically close because of Bluetooth's limited range, and the ability to daisy-chain devices to send messages further than Bluetooth's range.

[6] The Signal Protocol was integrated into the Bridgefy app and SDK by late October 2020, with the developers claiming to have included improvements such as the impossibility of a third person impersonating any other user, man-in-the-middle attacks done by modifying stored keys, and historical proximity tracking, among others.

[7] However, in 2022, the same security researchers, now including Kenny Paterson, published a paper describing how Bridgefy's usage of the Signal Protocol was incorrect, failing to remedy the previously discovered issues.
