The most valuable thing in a building is often the thing you throw away. Every demolition site is a small, chaotic bank, its value locked in tons of concrete, steel, and timber that are either landfilled or sold for scrap. Maeconomy, a Dutch startup, looks at that pile of rubble and sees a balance sheet waiting to be audited.
Founded in 2023 and based at the Brightlands Smart Services Campus in Heerlen, the company is building what it calls digital financial infrastructure for the circular economy. Its core product is a material passport platform that does more than just track. It analyzes, certifies, and assigns a future value to the material reserves inside buildings, framing them as tradable financial assets [Perplexity Sonar Pro Brief]. The goal is to connect public real estate with capital markets, turning cities into material banks.
The bet on municipal balance sheets
Maeconomy’s primary customers are not private developers, at least not initially. The company is targeting municipalities and social housing corporations, the owners of vast portfolios of public and semi-public buildings [Perplexity Sonar Pro Brief]. For these asset owners, the incentive is twofold: unlock latent value on their balance sheets and meet increasingly stringent circularity and carbon reduction mandates.
The platform’s wedge is combining inventory with market-making. First, it creates a detailed digital register of materials in a building, an “internet of materials” audit. This includes data on lifecycle, environmental impact, and projected residual value. Second, and more critically, Maeconomy is developing regional mechanisms to match material outflows from demolition with inflows for new construction projects. This includes buy-up guarantees that aggregate demand to de-risk reuse for contractors [Perplexity Sonar Pro Brief]. The company isn’t just selling a database; it’s attempting to build the first material-backed exchange, where buildings back materials “like gold backs money” [About | MAECONOMY, 2026].
Funding and the path to a marketplace
To accelerate this vision, Maeconomy raised a €1.5 million (estimated $1.62 million) seed round in June 2024, led by impact venture builder LUMO Labs with participation from regional development agency LIOF [The Next Web, June 2024] [LIOF, June 2024]. The capital is earmarked for developing the marketplace infrastructure and scaling the platform.

|---|---|
| 2024 Seed | $1.62M |
The round size is modest for the ambition, which points to a capital-efficient, software-first approach to a physically intensive problem. The backing from LIOF, a public agency, also signals alignment with regional economic and sustainability goals in the Netherlands, a frontrunner in circular construction policy.
The team building a bank for bricks
The founding team brings a blend of financial services and communications expertise, rather than pure construction pedigree. CEO Raoul Bhavnani has over 25 years in financial services, technology, and non-profit sectors, including a role as Chief Communications Officer at Betterment [DSSimon, 2025] [Raoul Bhavnani | Chief Communications Officer (CCO)]. Co-founders John Willett and Vince Meens round out the team [LinkedIn, 2026] [IOPlus, 2026].
This background is telling. Maeconomy is not a construction management tool; it is a financial instrument for the built environment. The team’s experience suggests a focus on structuring assets, communicating value, and building trust with institutional stakeholders, skills arguably as important as materials science when convincing a city to treat its old library as a treasury of reusable steel.
Where the foundation needs to set
The risks here are substantial, and they are less about technology than about market formation. Maeconomy must succeed on three difficult fronts simultaneously: creating the inventory, establishing the price, and building liquidity. The most direct competitor is Madaster, a well-established Dutch platform for material passports. Maeconomy’s differentiation is its explicit push into financialization and trading, moving from a library of materials to an exchange for them.
The next twelve months
The key milestone for Maeconomy in the coming year will be the announcement of its first live municipal or housing corporation deployments. The €1.5 million seed round is fuel to prove that its market-making mechanisms work at pilot scale. Success will be measured not in software licenses sold, but in tons of material successfully transacted on its nascent exchange.
