Unlike other messaging platforms, Signal operates based on donations as they are a non-profit organization.

The donations from users fund the operations of Signal and help keep the app free for everyone to use. Signal’s non-profit nature is different from other messaging apps like WhatsApp or Facebook though it is now owned by Twitter, an established for-profit company.

The Founder: Moxie Marlinspike

Moxie Marlinspike, the founder of Signal, has a history of creating innovative encryption technology. His work has continuously challenged the security industry and made online communications safer for everyone using it.

Early life and career of Moxie Marlinspike

Moxie has always had a passion for computer programming from an early age, and he was intrigued by the development of the internet. His early years were spent learning computer programming, and since then, he has cemented his place as an authority in the world of encryption.

Moxie’s early career began with his interest in Internet Relay Chats (IRC), a platform for communication through the internet. He gained his initial insights into encryption from the IRC and other similar online platforms.

During his early days, Moxie became more aware of the vulnerabilities that existed in existing protocols, and that led him towards security research.

Security research and ventures

Moxie Marlinspike’s passion drove him towards finding vulnerabilities in various security protocols to strengthen them. He created SSLstrip, a tool to reveal insecure communication channels.
