FOKUS Tech Stack

French IT services firm scaling digital transformation and industrial cybersecurity

IT Services and IT Consulting Lyon, Auvergne-Rhône-Alpes 51–200 employees Founded 2018 Privately Held

FOKUS is a Lyon-based IT services firm founded in 2018 now operating at 100+ employees with €9M ARR and 50% annual growth. The stack reveals a mixed-legacy footprint—heavy on .NET/C# (Windows Forms, WPF, ASP.NET) alongside modern web (Angular, React, Node.js) and enterprise databases (SQL Server, Oracle)—while active projects cluster around .NET migrations and critical-infrastructure security. The hiring shape (engineering-heavy with a dedicated 5-person security team) and project mix (SCADA, OT architecture, industrial compliance) signal a shift from generic software consulting toward specialized industrial and critical-systems work.
