Telness provides a cloud-based, fully automated platform that enables mobile operators and MVNOs to launch and run digital services more efficiently, with a focus on scalability, customer experience, and cost control.
Telness Tech is a Swedish telecommunications software company headquartered in Stockholm that develops and provides cloud-based infrastructure for mobile operators. Founded in 2016, the company originally operated as the Swedish mobile operator Telness, which became one of Europe's highest-rated operators (4.8 on Trustpilot). The technology built to power its own operator business was subsequently carved out as a standalone SaaS product, Seamless OS, and the company repositioned itself as a dedicated software provider. Telness Tech is led by telecom and technology executives with backgrounds at companies including Klarna, Telenor, Telefónica, Tink and Spotify. Major shareholders include Industrifonden and Viltor (JCE Group).
Telness Tech's flagship product, Seamless OS, is a cloud-native BSS/OSS platform that enables companies to launch, operate and scale mobile operator businesses with a high degree of automation. The platform integrates customer management, billing, provisioning, product configuration and network integrations into a single system, built on a modular, API-first architecture that connects to any telecom network. The business model is based on SaaS revenue, with operators paying to use the platform as an end-to-end solution. Typical customers include MVNOs, MNOs, MVNEs, internet service providers and enterprises seeking to offer connectivity as part of their product portfolio. The company has been described as a "Shopify for telecom" due to the low barrier to launching and running a mobile operator service.
Telness Tech has undergone rapid international expansion. The company secured EUR 5 million in funding from Industrifonden and Viltor in 2024 to accelerate global growth. In 2025, Telness Tech entered the U.S. market through a collaboration with T-Mobile, and New York Mobile became the first American MVNO to launch on Seamless OS. In parallel, the company partnered with VAS2Nets and Lebara to launch a new mobile operator in Nigeria. Telness Tech was named Cloud Native Network Leader at The Fast Mode Awards 2025 and has appointed John Browett, former Apple executive and chairman of Octopus Group, to its board. The company currently powers operators in the U.S., Europe and Africa, with its platform integrated in 64 countries.
