Case Study

HetPlein.eu — 12 verticals, 1 platform

A Dutch marketplace connecting customers with professionals across construction, accounting, legal, dental, landscaping, and seven more industries. Designed, built, and operated by NOVARINT.

The challenge

The Dutch market for professional services is fragmented. Customers struggle to find reliable professionals, and professionals struggle to reach new customers. Existing platforms charge high commissions and own the customer relationship. There was no Dutch-owned alternative that put both sides first.

What we built

A multi-tenant marketplace platform where each industry vertical (Klusplein, Boekhoudplein, Rechtplein, etc.) operates as an independent brand with its own domain, branding, and intake flow — all powered by a single codebase and shared infrastructure.

• Smart intake wizards that adapt per industry to capture precise customer needs
• Intelligent matching that pairs customers with the right professionals based on expertise, location, availability, and reviews
• AI-powered chat integrated via InnConnect for real-time customer support
• SEO-optimised landing pages auto-generated for every category and city combination
• WhatsApp Business integration for professional notifications and customer follow-up
• Complete data isolation between verticals with database-per-tenant architecture

Live on these domains

Each vertical operates as its own brand with its own domain, visual identity and intake flow — all powered by the same HetPlein engine.

Tech stack

The outcome

HetPlein serves over 60,000 users across 12 active verticals with 99.9%+ uptime. New verticals can be launched in days, not months. The platform improves weekly based on real operational data — because we operate it ourselves.

Every architectural decision, every feature, every optimization comes from running this platform daily. That's the Build & Operate advantage.
