What Quasus does
Quasus (operating as ALTEN Belgium) is a Benelux-based engineering and IT consulting firm that deploys technical consultants — mechanical engineers, embedded and application software developers, cybersecurity specialists, systems engineers, QA, and project managers — to enterprise customers on project-based assignments. The firm serves 12 vertical industries, including Aeronautics, Automotive, Banking/Finance/Insurance, Defence/Security/Naval, Energy/Environment, Industrial Equipment/Electronics, Life Sciences, Public Services/Government, Rail/Mobility, Retail/Services/Medias, Space, and Telecoms, addressing pain points such as R&D innovation, digital transformation, regulatory compliance, and skills gaps in regulated technical domains. The company holds ISO 9001:2015 and ISO 27001 certifications, qualifying it for security-sensitive and regulated mandates.
The firm operates as a wholly-owned subsidiary of ALTEN Group, a publicly traded French engineering services company (Euronext Paris) with 57,400+ employees globally and €4.10 billion in 2025 group revenue across 30 countries. Quasus itself was established in April 2018 and operates three offices — Brussels (Chaussée de Charleroi 112), Antwerp/Berchem (Berchemstadionstraat 72), and Luxembourg City — with 800+ employees generating €74M in 2025 local revenue. The go-to-market is enterprise field sales with direct client engagement; pricing is project-based and not publicly disclosed.
Revenue is generated entirely through professional services: engineering consulting (mechanical, materials, embedded software, application software, cybersecurity, data management, AI, systems engineering, PMO, QA, manufacturing, construction, EHS) and IT consulting (AMOA/business analysis, software testing, cloud & infrastructure, Green IT). The business model is fundamentally a technical staffing and consulting model in which consultant-day-rates are the primary revenue unit; differentiation comes from multi-disciplinary technical breadth, industry vertical specialization, and access to the larger ALTEN Group talent pool. Recent service-line additions in Artificial Intelligence, Data Management, Cybersecurity, and Green IT indicate a strategic broadening of the product surface beyond traditional engineering staffing.
