About us

We spent a decade running a telecom operator, so we know the complexity from the inside.

Over a decade we automated it, workflow by workflow, into a single intelligent operating layer: Seamless OS.

Born from frustration

Valdyr 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 it still holds today (4.8 on Trustpilot). In 2026 Telness was acquired by the Swedish MNO Telia.

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 Valdyr was born.
