What Telness Tech does
Telness Tech (legal entity: Telness Technologies) is a Stockholm-headquartered, cloud-native telecom software company that builds and licenses Seamless OS, a fully integrated BSS/OSS platform replacing legacy billing, charging, provisioning, and product catalog systems for mobile network operators (MNOs), mobile virtual network operators (MVNOs), MVNEs, and digital brands. Spun out of the Swedish MVNO Telness in 2022 — itself founded in 2016 by former Telenor executive Martina Klingvall — the company was purpose-built from the ground up rather than adapted from legacy telecom software, with API-first architecture, pre-built integrations, and an MCP server enabling AI model connectivity. Seamless OS is delivered as a core platform plus modular add-ons: AI Agents for autonomous multi-language customer support, Workflows for no-code process automation, Notifications with a WYSIWYG editor, Insights for AI-assisted analytics, Bundles for product catalog management, and Travel eSIM for digital connectivity products.
Telness Tech monetizes via subscription-based BSS/OSS platform licensing: a one-time implementation/onboarding fee plus recurring per-subscriber fees with a minimum monthly floor and optional premium add-ons, with pricing negotiated per operator. The company pursues a hybrid go-to-market combining direct enterprise sales (solution selling with live demos and proof-of-concept trials) and channel/partner distribution — most notably through the Truecaller travel eSIM partnership that embeds Seamless OS inside an app with hundreds of millions of users. With 24+ operators live or in deployment, headquarters in Stockholm plus offices in London, New York, and Madrid, and a pipeline reported at over 200M SEK in annual recurring revenue, the company has scaled from a single-market Swedish MVNO technology platform into a multi-region telecom infrastructure vendor with anchor customers including Telia, Lebara, Truecaller, and New York Mobile.
