About De Leeuw International

From Conventional Consultancy to Intelligent Service Delivery

De Leeuw is evolving professional consultancy from traditionally manual and fragmented service delivery towards an integrated, digitally enabled and AI-powered model.

De Leeuw is transforming professional consultancy through an integrated, digitally enabled and AI-powered operating model that connects people, processes, data and intelligence.

For more than seven decades, De Leeuw International has supported the construction and infrastructure industry with specialist professional expertise. Today, we combine this experience with AI, structured data and intelligent digital platforms to help clients plan, deliver and manage complex projects and assets with greater certainty and control.

We support governments, developers, infrastructure owners and investors across major capital programmes, providing the insight, governance and digital intelligence needed to make optimal decisions and deliver stronger outcomes.
