We launched Proton Mails in the summer of 2014 after a successful public crowdfunding campaign in which over 10,000 individuals donated over $500,000 to bring our shared vision to life. Since then, Proton has grown to become the world’s leading privacy company, used by millions globally, but we have never forgotten our humble beginnings. Proton services are operated by Proton AG, a Swiss corporation whose primary shareholder is the non-profit Proton Foundation based in Geneva, Switzerland.
