Software, Information Technology, Internet Services
ProtonMail is a service that provides easy to use secure email. ProtonMail's secure email system is designed around the principle of zero access. This means user data cannot be read by ProtonMail and turned over to third parties because ProtonMail servers do not store user encryption keys. The service is backwards compatible with insecure email providers such as Gmail and Yahoo and does not require the installation of any software to use. ProtonMail is based in Geneva, Switzerland and provides users additional protection through extraordinarily strong Swiss privacy laws.

Trading ProtonMail Stock
How to invest in ProtonMail stock?
Accredited investors can buy pre-IPO stock in companies like ProtonMail through EquityZen funds. These investments are made available by existing ProtonMail shareholders who sell their shares on our platform. Typically, these are early employees who need to fund a life event – house, education, etc. Accredited investors are then offered the opportunity to invest in this stock through a fund, like those used by hedge funds serving large investors. While not without risk, investing in private companies can help investors reach goals of portfolio diversification, access to potential growth and high potential return.
