Born from frustration

Telness Tech was born out of frustration. Frustration with the needless complexity that had been bogging down the entire telecom industry. We deemed it unacceptable. Telecom has to be as easy as streaming your favorite song on Spotify.

When former Telenor executive Martina Klingvall founded the Swedish MVNO Telness in 2016, the goal was simple — to raise the standards of an industry that had stopped innovating.

Building Europe’s highest-rated operator

We built a fully digital operator from the ground up, automating everything from onboarding to billing. It made Telness the highest-rated mobile operator in Europe, a title we still hold today (4.8 on Trustpilot).

Our customers loved us because they didn’t have to deal with us — it just worked. Behind that simplicity were thousands of user journeys, automated processes, and insights, all distilled into one AI-first tech platform.

From telco to tech company

Then we realized — let’s not keep this to ourselves. We carved out the technology to help other operators worldwide, and that platform became Seamless OS.

We left telecom and became a tech company — powered by some of the world’s best engineers with experience in both telecom and technology, from companies such as Klarna, Tink and Spotify. That’s when Telness Tech was born.

Since launching Telness Tech we have acquired several customers across Europe and the US, all of them running on Seamless OS.

The company is headquartered in Stockholm, Sweden with employees working all over Europe and the US.
