Signal is the world’s most widely used truly private messaging app, and our cryptographic technologies provide extra layers of privacy beyond the Signal app itself. Since launching in 2013, the Signal Protocol—our end-to-end encryption technology—has become the de facto standard for private commu...

We estimate that by 2025, Signal will require approximately $50 million dollars a year to operate—and this is very lean compared to other popular messaging apps that don’t respect your privacy.

    When Whatsapp was sold to Facebook in 2014, they had 55 employees. Considering the app had considerably less features and did not focus so heavily on encryption and privacy, Signal can be considered even leaner than Whatsapp.

    Now, for the actual breakdown, they have at least the following technical teams: desktop, android, iOS, server, calls (ringrtc), core (libsignal). If we assume a team has usually 5 people (manager, Sr SWE, Jr SWE, QA, maybe PM), that’s already 30 people. On top of that, they have an in house support team (don’t know the size but I wouldn’t be surprised if they have 10ppl on the payroll considering the number of signal users) and management (CEO, CTO, CSO, VP), which will quickly add up to around 50.
