MAECONOMY Raises €1.5M to Turn Building Materials into Tradable Circular Assets

Dutch circular-construction startup MAECONOMY has raised €1.5 million in fresh funding to scale a platform that treats building materials as auditable, financeable and tradable assets. The round was led by Eindhoven-based impact investor LUMO Labs alongside LIOF, the regional development agency of the Dutch province of Limburg.

Headquartered in Heerlen and led by founder and chief executive Vince Meens, MAECONOMY is tackling one of the heaviest footprints in the European economy. Construction and demolition account for more than a third of all waste generated in the European Union, and the sector remains among the most resource-intensive in the bloc. MAECONOMY’s thesis is that most of that waste is not waste at all — it is future inventory that has never been properly catalogued, valued or traded.

A financial layer for the built environment

The startup’s platform digitises building- and material-level data and applies algorithmic models to turn raw construction inputs into commercially actionable intelligence. In practice, it generates digital material passports for steel, concrete, wood and copper embedded in buildings, then attaches a financial value to those records. Owners can use the resulting data to report on embodied carbon, plan end-of-life recovery and, increasingly, sell or pledge materials that have not yet been extracted from a standing structure.

That last piece is where MAECONOMY is trying to carve out a defensible position. A growing number of software vendors already offer material passports as a compliance or ESG reporting tool. MAECONOMY is going a step further by building the financial layer that turns those passports into instruments institutional owners can actually trade, finance or collateralise. If it works, a building is no longer simply a cost centre at end of life — it becomes a material bank with a quantifiable residual value.

Regulation is doing part of the selling

The timing reflects a broader regulatory shift. Material passports are moving from voluntary best practice toward mandated documentation in a number of European jurisdictions, and the Corporate Sustainability Reporting Directive (CSRD) and EU Taxonomy are forcing large asset owners to produce far more granular data on embodied carbon and circularity than they have historically maintained.

For real estate investors, municipalities and developers, that creates a compliance burden and a market opportunity in the same motion. MAECONOMY is positioning itself at the intersection of the two, pitching its platform as both an audit-ready reporting layer and a route to monetising materials that previously sat on balance sheets as a future liability. The company is already working with Dutch municipalities and institutional asset owners, and plans to use the new capital to deepen those relationships before expanding across Europe.

Why LUMO Labs and LIOF wrote the cheque

The investor syndicate is telling in its own right. LUMO Labs runs a €100 million impact fund that recently drew a €6 million commitment from Spain’s state-owned investment arm SETT, and its mandate leans heavily towards early-stage deep tech and sustainability bets with measurable outcomes. LIOF, meanwhile, is one of the most active regional development agencies in the Netherlands and has been increasingly visible in circular-economy deals in the south of the country.

Together they bring the kind of patient, mission-aligned capital that a category-defining play like MAECONOMY requires. Building the financial infrastructure for the circular built environment is not a quick flip — it demands the slow work of standards-setting, integration with real estate software stacks and credibility with regulators and asset owners. A regional impact syndicate is often better suited to that pace than a generalist venture fund.

The bigger picture

MAECONOMY joins a small but growing cohort of European startups attempting to re-engineer the economics of construction, from digital twins of existing buildings to marketplaces for reclaimed components. Very few have tried to build the missing financial layer underneath all of it. With €1.5 million in the bank and a regulatory tailwind that is only strengthening, the Heerlen-based company now has a window to prove that digital material passports can carry real monetary weight — and that the walls of Europe’s existing buildings are, quite literally, assets waiting to be priced.
