What Sonetel does

Sonetel AB (publ) is a Swedish publicly listed (Nasdaq First North Growth Market Stockholm, ticker SONE) cloud communications provider that sells virtual business phone numbers and VoIP calling services primarily to solo entrepreneurs, freelancers, and very small teams. Its core product is virtual phone numbers available in 75+ countries, paired with cloud call forwarding, SIP trunking, and an interactive voice response (IVR) menu, all delivered through a self-serve web app, native iOS/Android apps, and a developer Communications API. The platform's differentiated layer is a set of AI-powered add-ons — call summaries, customer-call scoring, voicemail transcription with auto language detection, and AI-drafted follow-up emails — built on OpenAI's large language models and gated to Premium ($9.95/user/month) and Business ($29.95/user/month) tiers, with a Basic free plan and phone numbers priced from $1.79/month.

The business runs a product-led, freemium go-to-market with no direct field sales; customers sign up in roughly 30 seconds and upgrade through self-serve. As of Q4 2025 the company reported 33,600 paying customers across 170 countries, ARR of 25.9 MSEK (2.8 MUSD, +40% USD / +19% SEK YoY), 12.7 MSEK EBITDA over an 18-month transitional fiscal period, and a 67% equity ratio. Operations are split between Stockholm (HQ) and a Hyderabad R&D, customer-service, AI, and network operations hub. The Microsoft Skype shutdown in 2025 produced a major customer-acquisition tailwind, and the company has since reorganized around AI-driven development under a dedicated CAIO.
