What Developers House does

Developers House is a Netherlands-based interim agency, founded in 2002 and headquartered in Rhoon, that places software developers (.NET/Azure, Frontend, Fullstack) and UX designers at enterprise clients for engagements ranging from a few months to multiple years. The firm also performs bespoke custom software development for selected clients, with a portfolio that includes the Declaro expense declaration app for home healthcare workers, a time registration and planning tool for Prysmian Netherlands, and a planning and management system for Vogelzang Dakelementen. Its technology stack centers on the Microsoft ecosystem (.NET, Azure) combined with modern front-end frameworks (Angular, Vue.js), and it follows Scrum methodology for sprint estimation and MVP delivery.

The company is founder-led (Wai-Yin van Eijk as CEO/Founder; Iriane Ginzel as COO) and operates with a horizontal go-to-market targeting enterprise organizations across retail (Ahold Delhaize), telecommunications (KPN), manufacturing (Prysmian, Vogelzang), energy (Enexis, Dover Fueling Solutions), healthcare and government (Zorginstituut Nederland, home-care organizations), education (Hogeschool Rotterdam, Cito), and pensions (PGGM). Revenue is generated almost exclusively through professional services — consulting fees for developer and designer placements — with quote-based, negotiated engagement pricing rather than published rates. The firm maintains a Dutch-language website, blog, and case-study content marketing, supplementing direct outreach via website contact forms, email, and referrals.

Operating with 11-50 employees from a single Rhoon office, Developers House competes in the Dutch "interim/detacheren" segment against larger staffing firms by emphasizing a "Human approach," long-term developer relationships, internal knowledge-sharing rituals ("pizza sessions"), and hybrid work flexibility. It positions itself as more than a typical consultancy — a workplace for its consultants — and protects that culture through selective hiring rather than scale. No external funding, M&A activity, or geographic expansion beyond the Netherlands is documented in available sources.
