ProtonMail has raised $2M USD to protect online privacy

We’re happy to announce that ProtonMail has secured a financing round of $2M USD from Charles River Ventures (CRV) and the Fondation Genevoise pour l’Innovation Technologique (FONGIT). In our first fundraising last summer, we received over $550,000 in donations from over 10,000 supporters, and in the process set a new record for software technology crowdfunding. That critical early funding allowed us to go from a software project started in the CERN cafeteria to a fully functioning encrypted email service, supporting hundreds of thousands of users around the world.

This additional funding will allow us to accelerate our growth and get us closer to providing online privacy for everyone. We will be growing our team, and more importantly, speeding up the pace of development in the coming months. Privacy is important, and it is a race against time to build secure solutions like ProtonMail – before it is too late and privacy disappears entirely.

Introducing The New ProtonMail Homepage

With the release of ProtonMail BETA v1.14, our homepage gained a completely a new, fresh look. As with everything we do, the new design was largely driven by user feedback. Back in the Fall of 2014, we presented two designs to our Visionary and Lifetime crowdfunding supporters to get their feedback on the homepage design. The design they selected was one that was made by Synova Solutions and subsequently offered to ProtonMail free of charge.

The resulting new design was a collaborative project between the ProtonMail team and Synova Solutions’ Swiss and Vietnam based design teams that truly reflects the international nature of the ProtonMail project. Together, we took into consideration all comments which were submitted by our Visionary and Lifetime supporters. One of the most requested features was a way to login directly from the homepage – so we integrated the login form within the top of our homepage itself. Now, logging into ProtonMail is one less click away. (more…)
