What Infi Utrecht does

Infi is a privately-held Dutch custom software development consultancy founded in 2003 and headquartered in Utrecht, with additional offices in Amsterdam and Nijmegen. The firm specializes in the incremental modernization of business-critical legacy software — a practice it brands as 'behoud wat werkt, vervang waar nodig' (keep what works, replace where necessary) — for Dutch mid-market and enterprise clients in sectors including public broadcasting (NPO, NLZIET), public transportation (GVB), insurance (Scildon), logistics (BAS World, SnappCar), and healthcare (FocusCura/Luscii). Engagements are delivered through embedded teams of typically 2-7 developers working alongside a client Product Owner, with a deliberate focus on knowledge transfer to reduce client dependency. The company maintains a 1:1:1 senior-to-medior-to-junior ratio, targets ~75% billable utilization, and has codified its engineering methodology as 'The Infi Way', a publicly documented framework covering code quality, four-eyes reviews, CI/CD, and agile practices.

The underlying technology stack is mainstream full-stack: .NET, PHP, Node.js, React, Angular, Vue.js, and React Native for cross-platform mobile, deployed on Azure, AWS, and Google Cloud Platform, with infrastructure-as-code and automated testing as standard. Infi has added AI and LLM integration as a formal service line, covering private LLM deployment, third-party model integration (OpenAI, Claude, Gemini), GitHub Copilot rollout, and internally developed AI tooling such as an automated code-comment improvement tool using GPT-4 and Llama. Revenue is generated entirely through professional services — billable consulting hours for custom development and modernization projects — with pricing negotiated project-by-project. The company is bootstrapped, with no disclosed external funding, no M&A activity, and a management team led by founder Roy, CEO (Algemeen Directeur) Daniel, CTO Jeroen, and returning Director Patricia.
