Webstack B.v.

What Webstack B.v. does

Webstack B.V. is a Dutch boutique web development agency founded in 2005 and headquartered in Alphen aan den Rijn, Netherlands. The company designs and builds custom web applications, corporate websites, WooCommerce e-commerce platforms, customer portals, and legacy software modernizations for Dutch SMEs, mid-market firms, and select government/education clients. The company operates as a tightly held partnership between two co-owners, Robbert van Mourik (front-end) and Marco Wansinck (back-end), with a disclosed headcount band of 1-10 employees.

The technical stack centers on PHP with the Symfony framework for backend web applications, WordPress with Advanced Custom Fields for content-driven websites, WooCommerce for e-commerce, CapacitorJS for hybrid mobile apps, Nuxt.js for frontend, and Firebase for offline-capable mobile experiences. Notable project work includes ERP-middleware integrations (Mercado for Beekenkamp Ornamentals, Exact Online and Exact Bouw for clients like De Vries Warmte & Stoomtechniek), a custom Gift voucher backoffice for Fair Choice integrated with Intersolve and PostNL, an offline-first delivery app for WY Bloemisten, a learner management system for BMS Academy, and a route optimization SaaS (Routy) built on OSRM and Tile38. The company has also productized recurring-revenue offerings: Routy (route optimization at routy.nl) and Mijn Kantoor op Zak (subscription backoffice for mobile entrepreneurs).

Webstack monetizes through a mix of professional services (quote-based project work following an advisory meeting), managed services (hosting and maintenance), and subscription SaaS (Routy and Mijn Kantoor op Zak). Pricing is entirely quote-based; no public pricing is published. Go-to-market is sales-led and direct, supplemented by content marketing (Dutch-language blog, SEO around 'maatwerk software' / 'webapplicatie laten ontwikkelen' keywords) and client referrals. The company operates exclusively in the Netherlands, with no international presence indicated. It is bootstrapped with no disclosed external funding.
