Overview
Computer Task Group, commonly known as CTG, is an information-technology services and staffing company founded in Buffalo, New York, in 1966. The business began as Marks-Baer Inc., established by former IBM employees Randolph A. Marks and G. David Baer. Its early work focused on the medical industry, reflecting the founders' experience in healthcare-related computing and technology services. After expanding its staff during its first year, the company adopted the Computer Task Group name and subsequently became a public company in 1969. CTG developed from a regional specialist into a broader technology-services organization. In the mid-1970s it adopted a national growth strategy, and from 1980 onward it accelerated expansion through acquisitions. Within approximately five years it had acquired 15 companies, using acquisitions to add consulting, software, staffing, and sector expertise. Its first international acquisition was Shubrook International Ltd., a software-consulting firm based in Chertsey, England, purchased in 1986. This transaction established an international dimension to CTG's operating model. The company has supplied both professional services and technology staffing. Its activities have included application development and integration, application management, information security, systems and process assessment, IT consulting, and managed services. CTG has served organizations in healthcare, financial services, telecommunications, government, industrial markets, life sciences, and technology. Healthcare has remained an important area of specialization, supported by the company's historical roots and later investments in healthcare IT. CTG continued expanding its European healthcare and consulting capabilities through acquisitions. It purchased etrinity N.V., a healthcare IT company in Belgium, in 2013. In 2018 it acquired Soft Company, a Paris-based consulting and digital-services business. CTG Belgium also developed FASTBoX, a software-testing methodology whose name describes a framework for automated software testing based on experience. The company operated across North America, Western Europe, and India. A 2019 description identified approximately 3,950 employees worldwide, including about 2,650 in the United States and Canada and 1,300 in Europe, and referred to roughly 451 clients. IBM and SDI International were identified as its largest clients in that account. These figures are historical rather than a current operating statement. In August 2023, Cegeka, an IT services and consulting company headquartered in Hasselt, Belgium, announced an agreement to acquire CTG for approximately $107 million. The transaction was reported as involving a 74% majority stake and was announced as completed in December 2023. The acquisition changed CTG's ownership structure and placed the company within Cegeka's broader IT-services group. CTG's historical identity remains associated with technology consulting, healthcare IT, application services, managed services, and specialized IT staffing.
History
Computer Task Group originated in Buffalo, New York, in 1966 under the name Marks-Baer Inc. The founders, Randolph A. Marks and G. David Baer, were former IBM employees whose initial business experience was in the medical industry. The company grew to approximately 20 employees during its first year and changed its name to Computer Task Group, Inc. The new identity emphasized its role in supplying computing expertise and technical personnel to business customers. CTG became a public company in 1969. In 1975 it adopted a national expansion strategy, moving beyond its original regional base. Beginning in 1980, the company relied heavily on acquisitions to broaden its capabilities and geographic reach; it acquired 15 companies within roughly five years. This expansion added personnel, consulting capabilities, and technical specializations to a business that had initially concentrated on medical-sector work. CTG's first international acquisition came in 1986 with the purchase of Shubrook International Ltd., a software-consulting company headquartered in Chertsey, England. The transaction marked the beginning of a longer-term international development strategy. CTG later built a presence in Western Europe and India while continuing to operate in the United States and Canada. The company's service portfolio expanded beyond staffing to include software and application development, systems integration, application management, information security, IT consulting, and assessment of systems and business processes. Its target sectors included healthcare, financial services, telecommunications, government, industrial companies, life sciences, and technology businesses. Healthcare remained a notable area of expertise because of CTG's original market and subsequent healthcare IT investments. CTG acquired etrinity N.V., a Belgian healthcare IT company, in 2013. In 2018 it acquired Soft Company, a Paris-based consulting and digital-services company. CTG Belgium also created FASTBoX, a framework for automated software testing based on accumulated experience. The group consequently combined consulting and implementation work with testing, managed services, and contract or project-based technology staffing. A 2019 account described CTG as having approximately 3,950 employees worldwide, with around 2,650 in the United States and Canada and 1,300 in Europe. It also identified approximately 451 clients and named IBM and SDI International as the company's largest clients at that time. These figures describe a historical point in the company's development and should not be treated as current headcount or customer disclosures. CTG's ownership changed in 2023. In August, Cegeka announced an agreement to acquire the company for approximately $107 million, with Cegeka taking a 74% majority stake. Completion was announced in December 2023. The transaction placed CTG within Cegeka, a Hasselt-headquartered IT services and consulting group, and marked the latest major transition in CTG's history from an independently operated public technology-services company to a business controlled by a larger private-sector IT group.
