Overview

Euriware was a French information-technology and consultancy company focused on organizations in energy, industry, and defense. Its activities combined business and technology consulting, systems integration, and outsourcing. The company worked across enterprise information systems as well as industrial and technical systems, positioning it as a specialist provider for sectors with complex operational, engineering, and regulatory requirements. Euriware was fully owned by AREVA, the French energy group principally associated with nuclear power. Its ownership by AREVA shaped the company's sector orientation: Euriware's expertise was closely relevant to large-scale energy and industrial environments, where information systems, technical infrastructure, and operational processes must support safety, reliability, and specialized engineering needs. The available reference material does not establish the company's founding date, original founder, or headquarters location. The business operated through a network of 13 locations in France and maintained international activities through operations in the United States and Russia. Its United States presence was associated with former AREVA Federal Services. In Russia, Euriware's activities included Open Cascade, an entity connected with outsourcing and technical services. The company's broader service portfolio also included PEA Consulting for consulting and Open Cascade for outsourcing-related activities. Euriware's principal service areas were systems integration, consulting, and outsourcing. Systems integration covered enterprise systems together with industrial and technical systems. Consulting was delivered both under the Euriware organization and through PEA Consulting, while outsourcing was associated in part with Open Cascade. This combination allowed the company to address both strategic advisory work and the implementation or operation of technology environments. A major ownership transition occurred on 7 May 2014, when Capgemini acquired Euriware. The transaction ended Euriware's role as an independent AREVA-owned IT-services company and transferred its activities into Capgemini's organization. On 17 June 2015, Euriware was merged with Capgemini. Following the merger, the Euriware brand and corporate structure no longer operated as a standalone company. Open Cascade, which had been connected with Euriware's Russian operations, became a direct subsidiary of Capgemini after the merger. The available sources do not provide sufficient information to document later brand usage, detailed financial performance, named executives, or a separate post-merger operating strategy.

History

Euriware was a French company operating in consultancy and information technology, with a particular focus on energy, industry, and defense. Its service model covered three connected areas: consulting, systems integration, and outsourcing. Rather than concentrating only on conventional corporate IT, the company also worked with industrial and technical systems, reflecting the requirements of sectors where information technology is closely tied to engineering, production, infrastructure, and operational processes. The company's corporate identity and market position were closely connected to AREVA. Euriware was fully owned by the French energy group, which was principally known for its activities in nuclear power. This ownership placed Euriware within an industrial group whose operations required specialized technology capabilities. Euriware consequently served as an IT and consulting resource for complex environments in energy and related industries, while also addressing the needs of industrial and defense organizations. Euriware maintained a substantial French presence, with 13 locations in France. It also had international activities in the United States and Russia. The United States operation was associated with former AREVA Federal Services. In Russia, Euriware's activities included Open Cascade. The company also used subsidiaries or affiliated operating structures to deliver particular services: PEA Consulting was associated with the consulting business, while Open Cascade was associated with outsourcing. These arrangements extended the company's capabilities beyond a single centralized service organization. Its systems-integration work included enterprise systems and industrial or technical systems. This meant that Euriware's role could encompass the connection of business applications and organizational systems as well as technology supporting specialized industrial environments. Consulting formed another core activity, while outsourcing provided ongoing operational or managed-service support. Together, these activities gave Euriware a broad IT-services profile oriented toward large organizations and technically demanding sectors. The decisive change in Euriware's history came in 2014. On 7 May of that year, Capgemini acquired the company from AREVA. The acquisition shifted Euriware from AREVA's corporate structure into one of the world's major IT-services groups. It also created the basis for integrating Euriware's consulting, systems-integration, outsourcing, and sector expertise into Capgemini's wider business. The transition was completed institutionally on 17 June 2015, when Euriware was merged with Capgemini. From that point, Euriware ceased to operate as an independent corporate entity. Open Cascade, previously associated with Euriware's Russian operations, became a direct subsidiary of Capgemini after the merger. The available reference material does not document a founding year, founder, detailed executive history, financial results, or a continuing standalone brand strategy after the merger. Euriware is therefore best classified as a defunct French corporate IT-services brand whose business and related entities were absorbed into Capgemini.
