Wire Swiss

Wire Swiss GmbH is a software company headquartered in Zug, Switzerland, with a development center in Berlin, Germany. It develops Wire, a secure communications application designed for private messaging, voice and video calling, file sharing, and team collaboration. The application is available across iOS, Android, macOS, Linux, Windows, and compatible web browsers, allowing conversations to be synchronized among supported clients. Wire was created by a group of technology and communications specialists with backgrounds at Skype, Microsoft, and other internet companies. The company was founded in 2012 by Jonathan Christensen, Alan Duric, and Priidu Zilmer. Skype co-founder Janus Friis backed the project and later became associated with the company as executive chairman. The founders combined experience in communications infrastructure, product expansion, and interface design: Christensen and Duric had previously worked together at Camino Networks, while Zilmer had led design work connected with Skype and Vdio. The Wire application launched in December 2014. Its early proposition emphasized high-quality audio, an uncluttered user experience, cross-platform access, and privacy. The product initially encrypted messages between users’ clients and the company’s servers. In March 2016, Wire introduced end-to-end encryption for messaging and added video calling. It subsequently expanded group calling, ephemeral messages, screen sharing, file and media exchange, drawing tools, and integrations for services such as Giphy, YouTube, SoundCloud, Spotify, and Vimeo. Calls and messages can be exchanged through mobile, desktop, and browser interfaces, while Wire for Teams adds paid administrative and collaboration features for organizations. Security and transparency became central to the company’s identity. Wire uses the Proteus messaging protocol, developed by Wire and based on the Signal Protocol, while voice and video communications use established encrypted transport and media protocols. Wire began releasing the source code of its client applications under the GPLv3 license in 2016 and progressively opened its server code under the AGPL in 2017. The service is hosted within the European Union and is presented as operating under European Union legal protections. The company has changed leadership and ownership structures several times. In December 2017, former Huddle chief executive Morten Brøgger replaced Alan Duric as CEO; Duric moved to the board and resumed operational responsibilities as CTO and COO. Wire announced an investment round of $8.2 million in 2019 involving Morpheus Ventures and other investors, although the company’s broader funding history was not fully disclosed in the cited material. In July of that year, all company shares were taken over by Wire Holdings Inc. of Delaware. By August 2020, Wire Group Holding GmbH of Germany was identified as the sole shareholder of Wire Swiss GmbH. Since January 2024, the company has been headed by Benjamin Schilz, a technology and security executive who previously founded Acorus Networks and worked at F5. In April 2024, Wire announced a strategic partnership with the Schwarz Group under which companies in that group would invest in Wire. The partnership indicates an emphasis on enterprise and organizational communications rather than an advertising-supported consumer model. Wire’s stated commercial direction has included subscription-based team communications and premium services, while avoiding an advertising-based business model.

Wire Swiss GmbH was established in autumn 2012 by Jonathan Christensen, Alan Duric, and Priidu Zilmer. The founders brought experience from internet communications, software, and product design. Christensen and Duric had previously worked together at Camino Networks, a company they co-founded in 2005 that was later acquired by Skype, then a Microsoft division. Christensen had worked on extending Skype to additional platforms, including internet televisions and set-top boxes. Duric had also co-founded Telio. Zilmer had been associated with Vdio and led design work connected with Skype. Skype co-founder Janus Friis backed the new venture. The company’s principal product, the Wire application, was released on December 3, 2014. Wire initially offered text messaging, voice calls, media exchange, and a multi-device experience with an emphasis on audio quality and interface design. Its privacy claims later required clarification: shortly after launch, the company withdrew a statement suggesting that only conversation participants could read messages and conversation histories. At that stage, Wire’s message encryption protected traffic between clients and the company’s servers rather than providing complete end-to-end encryption. Wire expanded the product in August 2015 by adding group calling. In March 2016, it introduced end-to-end encryption for messaging and added video calling. The company used Proteus, a messaging protocol developed by Wire and based on the Signal Protocol. Voice communications used DTLS and SRTP, while video communications used RTP with encrypted transport and client-server connections protected by TLS. Wire also added features such as group conversations, ephemeral messages, file and media sharing, photo annotation, sketches, animated GIF support, and integrations with media platforms. Group calls could support up to ten participants, with a stereo mode intended to create a sense of spatial separation between speakers. The company began an open-source program in 2016. In July of that year, it released the source code for Wire’s client applications under GPLv3, while imposing restrictions on independently compiled clients’ interaction with Wire’s centralized servers. In April 2017, Wire began opening its server code, completing the process announced in September 2017 under the AGPL license. This open-source work supported the company’s broader privacy and transparency positioning. Wire also developed a business-oriented offering. A beta version of an encrypted team-messaging platform was announced in July 2017, followed by the formal release of a subscription communication solution for small businesses in October. Wire for Teams provided tools for managing members, assigning roles, and inviting guests to designated conversations. The company’s commercial model focused on paid team and premium services rather than advertising; executives stated that Wire would not build an advertising-supported business. Leadership changed in December 2017, when Morten Brøgger, formerly chief executive of Huddle, replaced Alan Duric as CEO. Duric joined the board and resumed the CTO and COO roles. In July 2019, Wire announced an $8.2 million investment involving Morpheus Ventures and other investors. The same year, Wire Holdings Inc. in Delaware took control of all company shares. By August 2020, Wire Group Holding GmbH in Germany was recorded as the sole shareholder of Wire Swiss GmbH. In January 2024, Benjamin Schilz became CEO. Schilz had founded Acorus Networks and later worked at F5, bringing a background in networking and security. In April 2024, Wire announced a strategic partnership with the Schwarz Group, with companies within that group expected to invest in Wire. The company’s documented direction therefore combines secure consumer-style messaging capabilities with enterprise collaboration, organizational administration, and European data-protection positioning. Wire remains associated with encrypted messaging, calling, and collaboration across mobile, desktop, and browser platforms.
