D-centralize

What D-centralize does

D-centralize B.V. is a Dutch private limited company founded in 2006 by Kees van den Broek and headquartered in the Klokgebouw building in Eindhoven, Netherlands. The company is structured as an innovation hub that builds and operates multiple vertical SaaS platforms across healthcare, education, low-code application development, and geodata. Rather than concentrating on a single product, D-centralize explicitly operates as a "group of SaaS companies" sharing technical infrastructure and talent, with each product serving a distinct vertical market.

The company's three core products are: Appsemble, an open-source low-code platform built on TypeScript, Node.js, and React, allowing users to compose applications from YAML-defined blocks; Pro6PP, a multi-country postal code database delivered as a cloud webservice with address validation, autocomplete, API access, and offline download options; and ITSLanguage, a speech technology platform providing real-time pronunciation analysis for language education and speech therapy, available as an API or full platform. ITSLanguage incorporates speech recognition and audio AI capabilities. All three products expose APIs for integration into partner systems and customer environments.

D-centralize generates revenue primarily through subscription and usage-based fees on its SaaS products, with Pro6PP offering pay-as-you-go and offline licensing options. The customer base spans Dutch government entities (Belastingdienst, Rijkswaterstaat, NZa, Gemeente Eindhoven), enterprise (ING, Energiedirect), and educational institutions (UvA, plus publisher partners MALMBERG, Boom uitgevers, VAN IN, Leesplanet, and Auris for ITSLanguage). The company is founder-owned with no disclosed external funding or institutional investors, operates with a small team of 11-50 employees, and distributes through direct sales, dedicated product websites, and reseller/publisher partnerships in the education vertical.
