What Brainbay does

Brainbay B.V. is a Dutch data and technology company founded in 2018 as a wholly-owned subsidiary of the NVM (Nederlandse Coöperatieve Vereniging van Makelaars en Taxateurs), the Dutch cooperative of real estate brokers and valuers. It serves as the data and technology arm of the NVM group, with exclusive custody of the TIARA member exchange system and the MIDAS property database, which together cover the Dutch residential, commercial, and agricultural real estate markets (5,931,420 objects, 8,519,786 residential transactions, and 116,579,226 photos). Its products power the property listings on Funda and are integrated with all major certified office automation systems used by NVM brokers (Realworks, CubicEyes, Kolibri, KeySoftware, skarabee, yesco, Pararius, Omniboxx, OSRE, Xitres, Realite).

The company's product portfolio is built on proprietary AI/ML capabilities, including a gradient-boosting Automated Valuation Model trained on more than 100 property and neighborhood features, a text mining classifier for property quality assessment, visual recognition on listing photos, a self-learning iterative model, and the EcoValue sustainability valuation model. It exposes these capabilities through six APIs (Object, Valuation, Reference, Price Trends, Market Information, and EcoValue) handling approximately 1,000,000 calls per day, alongside member-facing applications such as the Aankoop-tool, Inverkoopname-tool, Marktanalyse, Geografische Informatie, and the BNDL BiedWijzer bid-acceptance tool.

Brainbay operates a hybrid revenue model: subscription/recurring services to NVM members through the NVM member portal, API licensing to external parties (DatHuis, Flux, TaxAPI, Nexxtmove) under terms requiring demonstrated value for NVM agents, and professional services including research collaborations with ING Research, ABN AMRO, and NHG. Geographic scope is exclusively the Netherlands, with all operations run from its Utrecht headquarters (Orteliuslaan 951). The company is privately held by the NVM cooperative, with no external institutional investors or funding rounds disclosed.

Core offering

Brainbay develops and operates data-driven software products and APIs that manage, enrich, and distribute Dutch residential, commercial, and agricultural real estate data sourced from NVM's MIDAS database and TIARA exchange system. The company applies AI/ML (gradient boosting Automated Valuation Models, text mining, visual recognition) to deliver property valuations, market intelligence, comparable property references, sustainability impact assessments, and NVM-member-exclusive applications used in daily real estate workflows.

Product overview

Brainbay operates as a data-driven real estate intelligence platform with three core pillars: property data management (maintaining the most complete Dutch real estate database via Midas and Tiara), property market research (quarterly indices and market analysis), and property products (innovative tools making real estate data accessible). The portfolio consists of API-based products for automated valuation (Modelwaarde), price trends (Woningwaarde-index, Prijsontwikkeling), market information (Marktinfo), reference properties (Referentie objecten), sustainability valuation (Duurzaamheidswaarde-API, Verduurzamings-monitor), and object information (Object informatie/Gebouwpaspoort). NVM members access exclusive applications including Inverkoopname-tool, Aankoop-tool, Marktanalyse, Geografische Informatie, and Business Dashboard Datakwaliteit through the NVM member portal. The platform is powered by AI/ML using gradient boosting, text mining, and visual recognition technologies.
