Signal Foundation

The Signal Technology Foundation, commonly known as the Signal Foundation,[1][3] is an American non-profit organization founded in 2018 by Moxie Marlinspike and Brian Acton. Its mission is to "protect free expression and enable secure global communication through open source privacy technology."[5] Its subsidiary, Signal Messenger LLC, is responsible for the development of the Signal messaging app and the Signal Protocol.

History

On February 21, 2018, Moxie Marlinspike and WhatsApp co-founder Brian Acton announced the formation of the Signal Foundation, a 501(c)(3) nonprofit organization.[6] The foundation was started with an initial $50 million loan from Acton, who had left WhatsApp's parent company, Facebook, in September 2017.[7] The Freedom of the Press Foundation had previously served as the Signal project's fiscal sponsor and continued to accept donations on behalf of the project while the foundation's non-profit status was pending.[6] By the end of 2018, the loan had increased to $105,000,400, which is due to be repaid on February 28, 2068. The loan is unsecured and at 0% interest.[8]
