Rebtel Emerges as a Strong VoIP Contender with 20M Users and $80M Revenue
While Skype dominates consumer VoIP conversations, Stockholm-based Rebtel is making waves as a formidable compe*****. The company recently announced surpassing 20 million active users and generating $80 million in 2022 revenue, with projections reaching $100 million in 2023.
Key Growth Metrics
- 250% increase in app downloads and paying users since 2011
- 500,000 new users added monthly
- Profitable for two consecutive years (unlike Skype at Microsoft’s acquisition)
- $10 million in reserves without additional funding since its $20M Series A in 2006
Why Rebtel Stands Out
Rebtel carves its niche by offering cost-effective mobile calling, especially for international communication. CEO Andreas Bernström highlights their user base: “Many are first- or second-generation immigrants calling family abroad—a demographic often burdened by high carrier fees.”
Competitive Landscape
- Skype: 280M monthly users but unclear profitability
- Viber: 140M users (free service model)
- WhatsApp: Processes 10B daily messages (potential Facebook acquisition)
Expansion Strategy: White-Label VoIP SDK
Rebtel recently launched an SDK for developers to integrate its VoIP services into third-party apps. Key features:
- Freemium beta model (no restrictions to gauge market adoption)
- Targets mobile developers (iOS/Android/Windows Phone compatible)
- Monetization plans: SLAs for enterprises, licensing fees for heavy usage, and referral payouts for app downloads
Revenue Streams
- Direct-to-consumer subscriptions ($23/month with 5% conversion from downloads)
- Enterprise SDK services (premium support and licensing)
- Referral partnerships (paying developers for user acquisitions)
The Road Ahead
With profitability secured and a growing SDK ecosystem, Rebtel is poised to challenge Skype’s dominance by focusing on mobile-first solutions and developer-friendly integrations. As Bernström notes, “We’re scaling smartly—balancing innovation with sustainable growth.”
