The Signal Foundation, officially the Signal Technology Foundation,[2][3] is a non-profit organization founded in 2018 by Moxie Marlinspike and Brian Acton.[4] Its mission is "to develop open-source privacy technology that protects free expression and enables secure global communication."[7]

The foundation shares its name with the Signal messaging app.


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.[4][8] The foundation was started with an initial $50 million in funding from Acton, who had left WhatsApp's parent company Facebook in September 2017.[8] 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.[4]

The initial $50M in funding was a loan, not a donation, from Brian Acton to the new nonprofit Signal Technology Foundation. 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.[5]


As of October 2020, the Signal Foundation board of directors has three members:[7]

Acton is also the president.[5]
