Martijn Oostenrijk is CEO of Madaster, the materials cadastre for the built environment. Madaster is a data platform enabling asset owners, design & build teams, manufacturers and public sector to reduce embodied carbon, retain value and plan for reuse at scale. With material passports, verified data and support for area level registers, the platform turns design and procurement choices into verifiable outcomes across projects and portfolios. His vision is a world without waste, where transparent material data powers circular design and value retention.

With a management background working in financial services and construction, Martijn brings a sharp view on value, risk and measurable performance. He speaks regularly about digitalisation, regulations and shared industry standards that unlock resilient and circular assets across supply chains.

At Futurebuild he will show how material intelligence speeds decisions, derisks investments and proves impact.
