It's amazing what they produce with their headcount:

First, we have three distinct client teams, one for each platform (Android, Desktop, and iOS). These teams are constantly working: adjusting to operating system updates, building new features, and making sure the app works on a wide variety of devices and hardware configurations. We also have dedicated engineering teams that handle the development and maintenance of the Signal Server and all of its infrastructure, our calling libraries like RingRTC, and core libraries like libsignal. These also need constant development and monitoring.

Product and design teams help shape the future of the app and determine how it will look and function, while our localization team coordinates translation efforts across more than sixty languages. We even have a full-time, in-house support group that interfaces with people who use Signal and provides detailed technical feedback and real-time troubleshooting information to every other team. This is an essential function, particularly at Signal, because we don’t collect analytics or telemetry data about how people are using Signal.

How many people does it take to perform all that?

In total, around 50 full-time employees currently work on Signal ...
