What Verbonden.nl does

Verbonden B.V. (Verbonden.nl) is a Dutch private limited company headquartered in Groningen that provides cloud-based VoIP telephony and hosted PBX services to ZZP (self-employed) and MKB (small and medium business) customers across the Netherlands. The company operates its own proprietary SIP-based platform, exposing service through a 24/7 self-service web portal (mijn.verbonden.nl), native iOS and Android softphone applications, and a browser-based webphone. Technical features include AI-driven voicemail transcription, an HTTP webhook module for custom call routing and CRM integration, Microsoft Teams Direct Routing via a Callto365 SBC partnership, and VoIP-over-email fax. The company is a registered telecom provider with the Dutch Authority for Consumers and Markets (ACM registration 942960) and was founded by Rick de Jong; a related entity, Tussendoor internet & marketing, operates from Leeuwarden.

The revenue model is primarily subscription-based across three published tiers — Flexibel Basis at €8.50/month (targeted at ZZP), Flexibel Plus at €14.50/month (targeted at MKB), and the all-inclusive Compleet pakket at €21.50/month with unlimited domestic calling — supplemented by recurring fees for additional phone numbers, usage-based per-minute charges for non-included destinations, and one-time hardware and configuration fees for Yealink IP phones. Go-to-market is product-led growth: customers self-sign-up, self-provision, and self-manage their accounts through the portal, supported by an inside-sales inbox ([email protected]), a partner/reseller channel (Callto365) for Microsoft Teams deployments, and a network of vertical-specific SEO landing pages. The company's stated differentiation rests on contract-free, daily-cancellable service with up to 40% savings versus incumbent KPN business rates.

No revenue, headcount, or external funding data is disclosed. The company's public positioning — 'on the way to becoming one of the largest providers' in the Dutch VoIP market — combined with a 5-million-line market reference and a steady cadence of new modules and integrations (Openingstijden 2023, Vialer Plugin 2023, AI Assistent 2025) indicates an actively iterating SMB-focused operator rather than a venture-backed scale-up. Strategic optionality sits primarily in the Microsoft Teams channel and in AI-enabled feature upsell, while concentration risk is structurally low due to the long-tail ZZP/MKB customer base.

Direct peers

• Voys: Dutch VoIP provider for ZZP and MKB with very similar self-service cloud telephony, transparent pricing, and PBX features; positioned as the closest head-to-head competitor in the Dutch SMB VoIP segment.
• Sippy: VoIP platform provider offering hosted PBX, SIP trunking, and reseller/wholesale services; competes for Dutch and European SMB operators wanting carrier-grade cloud telephony.
• Belfabriek: Dutch VoIP and business telephony provider offering hosted PBX, phone numbers, and call features for SMBs; overlaps directly with Verbonden's ZZP/MKB target segment in the Netherlands.
• Voiceworks: Dutch business VoIP and UCaaS provider serving SMB and mid-market with cloud telephony, Teams integration, and SIP trunking; competes for the same Dutch MKB telephony budgets.

Emerging players

• 3CX: Global cloud PBX/UCaaS provider with a strong SMB channel; competes indirectly in Dutch SMB telephony through partners and is a common alternative to domestic VoIP operators.
• Voipgrid: Dutch VoIP technology vendor whose Vialer softphone is referenced in Verbonden's mobile app stack; comparable platform/operator model serving Dutch SMB telephony with developer-friendly tooling.

Broad incumbents

• KPN: Largest Dutch incumbent telecom operator offering traditional ISDN, fixed-line, mobile, and increasingly cloud VoIP; the legacy provider Verbonden explicitly benchmarks against on price.
• RingCentral: Global UCaaS leader offering cloud PBX, Teams integration, and contact center; sets the international benchmark against which Dutch SMB VoIP providers must compete.
• T-Mobile Netherlands (Tele2): Major Dutch mobile and fixed operator with bundled business telephony and broadband offerings; competes for the same MKB telecom wallet with broader connectivity portfolios.

Others

• Callto365: Microsoft-certified SBC partner that bridges Verbonden's platform to Microsoft Teams; comparable in that it provides Teams-PSTN connectivity, but acts as a partner/enabler rather than direct end-customer competitor.
