What NSI does

NSI is a Belgian-headquartered IT solutions integrator founded in 1993, operating across Belgium, Luxembourg, France, and Canada with 1,900+ employees and 600+ reported active clients. The company delivers end-to-end IT services spanning multi-cloud infrastructure, cybersecurity, AI/data analytics, modern workplace solutions, ERP integration (Odoo and Microsoft Dynamics with Power Platform), custom application development, Atlassian-based collaboration, software quality assurance/testing, and 5G/private mobile network deployment. NSI serves mid-market and enterprise customers across healthcare, manufacturing, finance and insurance, distribution and retail, government/public sector, and professional services. Named reference customers include Hydro-Québec, Loto-Québec, Bell Canada, Cossette, Fedérale Assurances, RTBF, Société Wallonne du Logement, Groupe Fruytier, Biron, and Trendy Foods.

Revenue is generated through professional services (consulting, implementation, project management), managed services/outsourcing, and staff augmentation, priced via quote-based, multi-year contracts. Distribution is direct via regional field-sales teams with on-site consultant delivery; the company explicitly emphasizes a proximity-first model anchored in 10+ office locations across its four country footprint. Pricing is not publicly disclosed and is tailored to client scope. Customer concentration is diversified across multiple verticals and geographies, with no single customer dependency disclosed in the input.

NSI has been majority-owned by Belgian IT services firm Cegeka since 2009, with regional investment firm Noshaq as co-investor, providing capital for an active acquisition program that includes 11 deals since 2000 (notably the 2024 acquisitions of CTG France, CTG Canada, CTG Luxembourg, StarDust, and Nubeo). The technology stack emphasizes third-party platform integration (Microsoft, Odoo, Atlassian) rather than proprietary IP, with operational certifications including ISO 9001 and Luxembourg PSF status. The company is led by CEO Manuel Pallage.
