Respected technology leader in its industry, Swiss Post, acquires majority stake in Switzerland-Hungary-based IT security company

Swiss Post has acquired a majority stake in Tresorit, a Swiss-Hungarian company that offers encrypted, cloud-based file sharing and collaboration services. The success is not out of the blue. The startup founded in 2011 has been featured on the Financial Times list of the 1,000 fastest-growing European companies regularly and is represented in Budapest/Hungary, Munich/Germany and Zurich/Switzerland by around 120 employees. In addition, its services are trusted by more than ten thousand corporations and firms worldwide. The company has also sparked interest from international investors, such as 3TS Capital Partners, PortfoLion and Day One Capital in recent years. Private investors Márton Szőke and Andreas Kemi have been involved since the start and Márton Anka, the founder of LogMeIn jumped on board some years later.

Tresorit was founded in 2011 by István Lám, Szilveszter Szebeni and György Szilágyi. Lám and Szebeni worked in the CrySyS Data and System Security Laboratory as computer science students at the Budapest University of Technology and Economics. The foundations of Tresorit’s technology were born during their work and research there. They were joined by György Szilágyi, who brought economics, business, and product development knowledge to the mix as a student at the Corvinus University of Budapest. The trio closed their first investment round in 2012 when Euroventures and nine angel investors, including serial entrepreneur Márton Szőke, and the Vice President of EPAM at the time, Balázs Fejes, and Swiss businessman Andreas Kemi, who has been supporting Tresorit as Chairman of the Board since then, invested €1.5 million. Márton Anka, the founder of LogMeIn, joined the list of investors in 2017. Tresorit secured its largest investment in 2018 when it raised €11.5 million in a round led by 3TS Capital Partners, joined by PortfoLion and Day One Capital. As a result of the sale of Tresorit, the PortfoLion team have completed their second successful international exit within six months.

Tresorit’s patented end-to-end encryption service provides the highest level of security for enterprise users looking for cloud-based file storage and sharing. In recent years, the solution has received accolades such as, among others, the Gartner Peer Insights Customer Choice 2020. The essence of the technology is that it encrypts all data before it is sent to the cloud. Thanks to the “zero knowledge” principle used, the decryption key never leaves local devices and never reaches the cloud.
