ProtonMail Raises $2M USD

High security email service dramatically accelerating development to meet immense demand

March 18th, 2015 (Geneva, Switzerland)

ProtonMail, a leader in email security and privacy, is announcing today that it has secured $2M USD in a financing round led by Charles River Ventures (CRV) and the Fondation Genevoise pour l'Innovation Technologique(FONGIT). The company will use these funds to further invest in the development of new features and to scale infrastructure to meet the growing demand for the service.

ProtonMail launched its beta service in May 2014. Explosive demand overloaded its servers within 48 hours, forcing the company to seek funding to support the rush of new users. This latest round of funding comes on the heels of the more than $550,000 raised by the Swiss startup in July 2014 from over 10,000 crowdfunding supporters, which set a record for a software technology project.

ProtonMail is now used worldwide by business professionals, journalists, activists, and individuals who value privacy in their communications. While ProtonMail is still in beta, more than 350,000 users have already signed up for the service. The company’s innovative email service distinguishes itself with its ease of use that allows anyone, regardless of tech skill, to benefit from end-to-end email encryption.

"This funding will allow us to finally bring ProtonMail’s automatic end-to-end email encryption to the mainstream," says ProtonMail Co-Founder Andy Yen. "We are happy to have found partners who understand our long term vision of online privacy and can help us succeed."

With support from FONGIT, ProtonMail will be moving into new offices in Plan-les-Ouates, Geneva and expanding its datacenters in Switzerland, where the service is hosted under the protection of strict Swiss privacy laws.

"As an organization backed by the State of Geneva, our mission is to support valuable companies in leveraging the unique assets of Switzerland and Geneva, such as the robust framework for security and privacy," says Antonio Gambardella, Director of FONGIT, "We see tremendous potential in ProtonMail and look forward to supporting the company as it grows."

"The past decade has been marked by a massive erosion of privacy and we’re working to reverse this trend,” says Andy Yen. "Encrypted communications is the future and ProtonMail is committed to making online privacy a reality again for all Internet users."

My opinion
It's very nice these technologies are receiving funding. There should be more projects that enable access to secure communication for the broad audience. Another example is Threema, a secure messenger app for mobile phones, that is also from Switzerland, uses strong end to end encryption and is very user-friendly. It's one of my favorite communication apps.
