Signal Private Messenger is an open-source, end-to-end (E2E) encrypted cross-platform messaging service available for Android, iOS and Windows operating systems.

Later, in late 2011, Whisper Systems was acquired by Twitter. This was done mainly for early support.
Marlinspike later left Twitter in 2013 and founded Open Whisper Systems to continue the development process of RedPhone and TextSecure. In 2015, RedPhone was merged into TextSecure to become Signal for Android.
After leaving Whatsapp (Acquired by Facebook Inc. in 2014) in 2017, Brian Acton( co-founder of Whatsapp Inc.) co-founded the Signal Foundation alongside Marlinspike in 2018, with initial funding of $50 Million from Acton.
