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. [3] [7] 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. [3] 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]

Senior leadership

Signal Foundation has been led by a Chairman, which is separate from the leadership roles of Signal Messenger.
