What SpecifiedBy does
SpecifiedBy, founded in 2013 and headquartered in Edinburgh, UK, operates a two-sided B2B marketplace for building product specification. Architects, architectural technologists, and construction specifiers use the free web platform (specifiedby.com) to search, filter, compare, and price over 100,000 building products across 24+ categories — including floors, walls, external works, bathroom, doors, lighting, HVAC, brick, kitchen, and more. Building product manufacturers pay subscription listing fees to make their catalogues searchable and comparable, generating qualified leads from the specifier audience.
The underlying platform is a web-based database with structured product metadata, side-by-side comparison tools (up to 3 products), and resource modules covering Building Regulations, a BIM Dictionary, Building Product CPDs, and Building Product News. Following a 2024 rebrand to CausewayOne Product Explorer, the product has been integrated into Causeway Technologies' CausewayOne construction operations platform, with Single Sign-On access for the parent's contractor customer base and a stated roadmap toward product data interoperability across the "Golden Thread" of construction project data.
Commercially, SpecifiedBy runs a product-led growth motion: zero-friction free sign-up for the specifier side, with monetisation concentrated on manufacturer listing subscriptions. Distribution is UK-domestic and organic, driven by content (CPDs, news, BIM resources) and search. The company is a wholly-owned subsidiary of Causeway Technologies (Registered No. 3921897, Gerrards Cross), with disclosed funding of approximately $930K raised across four early-stage rounds between 2013 and 2015.

SpecifiedBy competitors and assessment
Company assessmentEmerging players
- Materially: European curated marketplace for innovative and sustainable building materials targeting architects and designers. Comparable specifier-facing product discovery model with a narrower, sustainability-led niche.
Broad incumbents
- Autodesk Construction Cloud: Broader construction operations suite (including BIM 360, BuildingConnected, Assemble) used by contractors and designers. Competes indirectly as a unified platform that increasingly embeds product data and specification workflows.
- Procore: Major construction management platform for contractors and project owners. Relevant as the broader ecosystem within which CausewayOne competes, and as a potential adjacent platform where product data and specification could be embedded.
- Trimble Construction: Provider of construction technology including Trimble Connect and building data tools. Comparable as an established incumbent integrating design, BIM, and construction data, with overlapping product-data ambitions.
Direct peers
- BIMobject: Global platform hosting manufacturer BIM objects and product data for architects and specifiers. Closely comparable two-sided marketplace monetising building product listings with similar discoverability and comparison functionality.
- NBS (National Building Specification): UK-based specification platform providing NBS Source (manufacturer product data) and NBS Chorus (specification writing software) to architects and designers. Most direct UK-headquartered competitor to SpecifiedBy's product-research and specification use case.
- Cobuilder: Provider of structured building product data and digital product passports for the construction industry. Comparable focus on standardising manufacturer product data for use across design, specification, and procurement workflows.
- Archiproducts: International product directory and search engine for architecture and design products. Comparable curation, categorisation, and manufacturer-listing model targeting the same specifier and architect audience.
- Archello: Global platform for architecture and design products, projects, and firms, offering manufacturers a channel to reach specifiers. Overlaps directly on product discovery, comparison, and manufacturer marketing for architects.
Others
- Causeway Technologies: Parent company of SpecifiedBy and operator of the CausewayOne construction operations platform. Direct corporate parent — relevant as the ecosystem into which SpecifiedBy is integrated and through which its SSO and cross-promotion flows.
