About Signal Foundation

Signal Foundation is a non-profit organization dedicated to protecting free expression and enabling secure global communication through open-source privacy technology. Founded by Brian Acton, co-founder of WhatsApp, and Moxie Marlinspike, Signal Foundation operates in the privacy and security market, serving individuals and organizations who prioritize secure communication. The foundation's core product, Signal, is a messaging app that offers end-to-end encryption, ensuring that messages are only readable by the intended recipients. Signal Foundation's business model is unique as it relies on donations and grants rather than traditional revenue streams like advertising or subscription fees. This approach aligns with its mission to maintain user privacy and avoid monetizing user data. The foundation also contributes to the open-source community by publishing its technology and sharing knowledge to encourage adoption by other companies.
