What Tussendoor Internet & Marketing does

Tussendoor Internet & Marketing B.V. is a Dutch WordPress specialist founded in early 2010 by Rick de Jong and Erik Benjamin van der Meulen and headquartered in Leeuwarden, Friesland. The company builds and maintains proprietary WordPress plugins targeting three SMB verticals in the Netherlands: real estate agents (Makelaar plugins with native connectors to Realworks, Kolibri, Eyemove, Skarabee, Pyber, Tiara, and Goes & Roos CRMs), automotive dealers (Autobedrijf & Voertuigen plugin with Hexon and Open RDW kenteken integration), and Dutch WooCommerce merchants (integrations to Bol.com, WeFact, HostFact, Moneybird, Mollie, and Billink). Underlying technology is PHP/WordPress with WooCommerce, custom plugin architecture, REST/XML CRM connectors, Google Maps APIs, and an online license management dashboard at app.tussendoor.nl.

The business operates on four revenue streams: annual recurring plugin licenses (subscription, domain-bound, self-serve via dashboard), custom WordPress and WooCommerce development (quote-based professional services, including an inbouw/integration service), WordPress hosting and maintenance (managed services with annual inflation adjustments), and digital marketing services covering SEO, SEA, social media, and email. Distribution is direct via tussendoor.nl and through a WordPress partner/reseller program for agencies. Tussendoor is part of Junction creative + digital agency and operates with ~10-12 employees in a flat organizational structure.

Direct peers

• Yoast: Dutch-founded WordPress SEO plugin company (now part of Newfold Digital) that combines a flagship plugin product with SEO training and services. Comparable in the Dutch WordPress-plugin-plus-services positioning and in-depth SEO focus that mirrors Tussendoor's SEO service line.
• WP Media: Dutch-rooted WordPress performance company behind WP Rocket, Imagify, and Rank Math SEO. Comparable as a Dutch WordPress specialist that scaled from plugin roots into a broader product portfolio serving global SMBs.
• YITH WooCommerce: Italian WooCommerce plugin vendor with a broad portfolio of e-commerce extensions. Comparable as a WooCommerce plugin shop targeting SMB merchants, though broader and more horizontal than Tussendoor's vertical-specific integrations.
• Savvii: Dutch managed WordPress hosting provider combining hosting with custom development and agency services for SMB clients. Comparable in the managed hosting + services overlap with Tussendoor's hosting and maintenance offerings.
• Pronamic: Another Dutch WordPress specialist based in Leeuwarden with a focus on payment and integration plugins (Mollie, Buckaroo, etc.). Most directly comparable peer given shared city, similar team size, and overlap between plugin + agency model for Dutch SMBs.

Broad incumbents

• SiteGround: Established managed web hosting provider with strong WordPress positioning and SMB focus. Comparable on the hosting/maintenance side but lacks Tussendoor's vertical plugin products and Dutch market specialization.
• Automattic: Parent company of WordPress.com, WooCommerce, Jetpack, and Akismet. Comparable as the steward of the WordPress/WooCommerce ecosystem on which Tussendoor's products depend, but vastly larger and broader in scope.
• WP Engine: Large US-headquartered managed WordPress hosting platform serving SMB and mid-market. Comparable in the managed WordPress hosting service line, but operates at significantly greater scale and without Tussendoor's vertical CRM integration depth.

Regional players

• Van Ons: Dutch digital agency offering WordPress, custom development, and digital marketing services to SMB and mid-market clients in the Netherlands. Comparable as a Dutch-region digital services competitor with overlapping service lines, though without Tussendoor's proprietary vertical plugins.

Others

• Realworks: One of the dominant Dutch real estate CRM platforms with which Tussendoor's Makelaar plugin integrates. Relevant as a partner today, but also represents a potential disintermediation risk if Realworks ships first-party website tooling.
