Case Study: Rebtel scales global expansion and boosts conversions with Adyen

How Rebtel revolutionized international calling with Adyen

Rebtel, a Swedish VoIP start‑up turned global mobile‑first calling app, faced growing pains as it scaled: outdated web‑based checkouts, frequent downtime, and opaque pricing from multiple payment providers hindered international expansion and a seamless mobile experience. With a business model reliant on recurring payments and local payment preferences across markets, Rebtel needed a single payments partner that could support subscriptions, automatic refills and local payment methods worldwide.

Partnering with Adyen gave Rebtel an all‑in‑one solution: out‑of‑the‑box support for local methods (e.g., giropay, iDEAL, UnionPay), Interchange++ transparent pricing, tokenization for one‑click payments, and RevenueProtect risk management powered by machine learning and issuer signals (TC40s). The result was higher conversion through seamless payments and salesperson‑assisted app adoption, clearer costs and fewer pricing negotiations, and stronger fraud controls—backed by close technical and account support across Rebtel’s key markets.
