History

cycos AG traces its origins to 1984, when Pfleiderer und Partner Ing. GmbH was founded. In 1991, the company was renamed PP-Com Telecommunications + Networking GmbH. In 1998, it received the Byte Award '98 for its Unified Messaging server 'mrs'. In 1999, the company was converted into CYCOS Aktiengesellschaft. In 2000, cycos acquired Dolphin Communication Technologies GmbH and Maier Bürokommunikationssysteme GmbH, and in the same year, cycos went public. In 2003, Siemens AG became the majority shareholder. In 2006, cycos mrs received the Frost & Sullivan Award for Product Differentiation Innovation in the Unified Messaging and Communications market; also in 2006, cycos presented a prototype of the world's first Communications Suite for Microsoft Dynamics CRM 3.0 at CeBIT. In 2008, cycos launched mrs Vanguard, the most comprehensive Unified Communications software suite on the market at that time. According to a study by MZA, a market research firm specializing in IT and telecommunications, cycos AG was the market leader in Western Europe for Unified Messaging solutions at that time (study: The Western European UC Applications Market Competitive Environment - 2008 Edition). At the end of 2009, cycos AG transferred its sales activities to its then parent company Siemens Enterprise GmbH & Co. KG (now Unify GmbH & Co. KG). Two years later, the phasing out of the 'mrs' product was initiated to reposition the company as a service provider. In the same year, cycos AG was named Center of Competence for what is now Unify GmbH & Co. KG and has since focused mainly on services for the Unify group. By resolution of the Annual General Meeting on 13 May 2011, the company was renamed 'cycos AG'. The in-house product 'mrs' reached End of Life in October 2012 and End of Service in October 2014. In January 2015, the stock exchange listing ended at the company's own request. In spring 2016, Atos S.E. acquired the Unify group, making cycos AG part of the Atos Group. In 2023, the Atos Group was divided into two areas: Atos and Eviden. cycos AG was assigned to the Eviden area.
