What Concular does

Concular is a Berlin and Stuttgart-based digital ecosystem for circular construction, founded in 2020 by Dominik Campanella and Julius Schäufele, building on their prior work at restado.de. The company combines a software platform (Concular One, CircularLCA, Life-Cycle Passport), expert consulting services (Pre-Deconstruction Audits per DIN SPEC 91484, Connection Use Concepts per DIN SPEC 91525), and an online marketplace (concular.shop) for recovered building materials. Its proprietary Circularity Performance Index (CPX) scores building components on circularity using a database that integrates German Federal Statistical Office recycling rates with ten years of marketplace transaction data, and BIM/IFC-based automated product mapping accelerates circularity assessment.

The company serves property holders (Bestandshalter), project developers (Projektentwickler), consultants and planners (Beratende und Planende), building material manufacturers, commercial tenants, and public-sector clients across the DACH region. Revenue is generated through three streams: professional services consulting, recurring software subscriptions (Concular One, CircularLCA), and marketplace transaction fees on material sales. Distribution relies on enterprise field sales augmented by a Circularity Partner network, with a free Pre-Check as the initial qualification touchpoint.

Concular self-identifies as the German market leader for circular construction, claiming 1,000+ projects, and operates from six offices (Berlin, Stuttgart, Düsseldorf, Hamburg, Dresden, Vienna). It has raised approximately EUR 4-5M in disclosed funding across three rounds through September 2023, with strategic investors including STRABAG, Hagedorn, Landmarken, KVL Bauconsult, and board member Martin Rodeck. Anchor customers include Deutsche Bahn, Siemens Real Estate, Tegel Projekt GmbH (framework agreement through 2032), B&B Hotels, Behnisch Architekten, and the NRW state government (October 2025 cooperation for public housing pilots).

Revenue model

1. Consulting and Expert Planning Services: Concular provides comprehensive consulting services for circular construction including portfolio strategy, scenario development, audits, and circular specialist planning from project initiation through completion. Services include Pre-Deconstruction Audits (PDA) per DIN SPEC 91484, connection use concepts per DIN SPEC 91525, and LCA calculations.
2. Software Subscriptions and Platform Access: Concular One platform subscription providing access to digital tools for resource capture, match-making, and circular planning. CircularLCA software for LCA and building resource passports. Includes unlimited user and guest licenses.
3. Marketplace Commission / Material Match-Making: Concular operates a marketplace (concular.shop) where recovered building materials are sold. The company facilitates matches between material supply (from demolition/renovation) and demand (new construction projects), enabling materials to move directly from deconstruction to new construction sites.

Core offering

Concular operates a digital ecosystem for circular construction, combining the Concular One software platform, CircularLCA life-cycle assessment software, and a Building Resource Passport (Life-Cycle Passport) with BIM-based material digitization and automated product mapping. The company also runs an online marketplace (concular.shop) for recovered building materials, an Urban Mining cadastre for municipal building inventories, and project-based consulting and specialist planning services covering Pre-Deconstruction Audits, connection use concepts, and LCA calculations. Revenue derives from software subscriptions, professional services, and marketplace transactions, with the platform addressing a 1% current reuse rate for building materials in Germany.

Product overview

Concular is a digital ecosystem for circular construction combining a software platform with consulting services. The core offerings include: Concular One (central platform for material flow optimization), Life-Cycle Passport (digital resource documentation across building lifecycles), CircularLCA (LCA and circularity assessment for certifications), Circularity Performance Index (CPX, quantitative circularity scoring), and the Material-Shop (marketplace for recovered materials). Supporting services encompass Urban Mining consulting, Pre-Deconstruction Audits (DIN SPEC 91484), Connection Use Concepts (DIN SPEC 91525), and the Academy for professional education. The platform leverages BIM/IFC integration, automated product mapping, and a proprietary database built on recycling statistics and 10 years of marketplace transaction data.

Direct peers

• Madaster: Madaster operates a digital material passport registry for buildings and assets, enabling circularity tracking across the building lifecycle. It is the closest direct competitor to Concular's Life-Cycle Passport and Concular One platform, with overlapping target customers (property owners, developers, architects) and similar BIM/IFC integration.
• Rotor: Rotor is a Brussels-based cooperative providing architectural salvage, deconstruction services, and circular construction expertise across Europe. It is comparable to Concular's Urban Mining and consulting business, particularly in selective deconstruction, reuse advisory, and circular design services.
• One Click LCA: One Click LCA provides life-cycle assessment software widely used for green building certifications (DGNB, LEED, BREEAM). It directly competes with Concular's CircularLCA product for LCA and certification workflows in the same architect/developer buyer segment.
• Excess Materials Exchange: Excess Materials Exchange (EME) is a marketplace for industrial and building materials seeking reuse. It is comparable to Concular's concular.shop marketplace in enabling match-making between material supply from demolition/renovation and demand from new construction.
• restado: restado.de is a German marketplace for salvaged building materials and the predecessor venture from which Concular's founders drew 10 years of marketplace data. It is comparable as the original recommerce platform for recovered construction materials in Germany.
• Cycle.Up: Cycle.Up is a German PropTech focused on circular construction with material marketplaces and digital tools for reclaimed building components. It targets a similar buyer base (developers, planners, contractors) and overlaps with Concular's consulting and marketplace offerings.

Regional players

• Salza / Salvalaggio: Salza is a Dutch platform curating reusable building materials from renovation and demolition projects. It is comparable as a regional recommerce marketplace for the construction sector, addressing the same circular construction opportunity but focused on the Netherlands/Benelux.

Broad incumbents

• Build Reuse: Build Reuse (formerly the Center for Reuse) is a US-based industry organization supporting the building materials reuse sector with standards, training and advocacy. It is broadly comparable as a sector-organizing incumbent addressing the same circular construction opportunity at a more institutional level.
• Autodesk: Autodesk provides BIM (Revit) and construction collaboration platforms that architects and engineers use as the upstream system feeding Concular's IFC-based workflows. It is comparable as a broad incumbent that could embed circularity/material passport features into its widely-deployed design software.
• Nemetschek Group: Nemetschek is a European provider of AEC software (Allplan, Graphisoft, Solibri) widely used by German architects and engineers. It is comparable as a broad incumbent whose BIM and BIM-coordination tools overlap with Concular's IFC-driven circularity workflows.
