Signal is owned and run by the nonprofit Signal Technology Foundation , which fully owns its subsidiary Signal Messenger LLC that develops the Signal app.

Who actually “owns” Signal?

  • The Signal app is developed by Signal Messenger LLC, a company created specifically for the app and protocol.
  • Signal Messenger LLC is wholly owned by the tax‑exempt Signal Technology Foundation (often just called the Signal Foundation).
  • The foundation is a nonprofit based in the United States and operates Signal as a donation‑funded project rather than an ad or data‑driven business.

Founders and leadership

  • The Signal Foundation was founded in 2018 by cryptographer Moxie Marlinspike (Matthew Rosenfeld) and WhatsApp co‑founder Brian Acton.
  • Acton put in around $50 million in initial funding and became the foundation’s executive chairman.
  • Moxie Marlinspike was the first CEO of Signal Messenger until 2022, after which Brian Acton became CEO and has remained in that role since 2023.

Is Signal owned by a big tech company?

  • Signal is not owned by Facebook/Meta, Google, Apple, Twitter, or any other large corporation.
  • Its structure (nonprofit foundation + wholly owned subsidiary) is designed so that there are no outside shareholders pushing it to monetize user data or inject advertising.
