What Numerical Algorithms Group does

Numerical Algorithms Group (NAG) develops numerical software and technical services for banks and financial institutions, engineering and manufacturing firms, energy companies, life-sciences organizations, and academic or government research institutions. Its customers use these capabilities for quantitative finance, simulation, optimization, scientific research, and computationally intensive workloads. NAG has operated since 1970 and reports offices in Oxford, the United States, and Japan, with services marketed across EMEA, North America, and Asia Pacific.

The product portfolio centers on the NAG Library, which provides rigorously tested numerical routines across statistics, optimization, linear algebra, interpolation, integration, special functions, and related domains through C, C++, Fortran, Python,.NET, and Java interfaces. NAG also sells optimization solvers, dco/c++ automatic differentiation for C++ derivatives, a commercial Fortran compiler, the VSMS managed HPC service, and Storm, a cloud-provider-agnostic platform running Slurm on Kubernetes with Open OnDemand. Its professional-services team handles HPC optimization, cloud migration, hybrid-cloud design, and vendor-agnostic infrastructure work using major processor and cloud technologies.

NAG earns revenue through annual commercial software licences bundled with maintenance, updates, and technical support, plus project-based consulting and recurring managed-service engagements. Pricing is quote-based and varies by product, deployment size, support requirements, engagement scope, duration, and expertise; enterprise software is sold through direct technical sales, proof-of-concept work, and benchmarking, with case studies, webinars, and technical content supporting lead generation. The supplied history describes NAG as a not-for-profit, member-backed company within n2 Group that reinvests revenue into R&D and has no external financial stakeholders.
