“We Were Welcomed With Open Arms” Tradedoubler CEO Talks US Expansion, LLM Solutions, and Affiliate Fraud

As Tradedoubler continues to push into new markets, the US has emerged as a key focus. 

After launching its first American office in Miami in 2025, the network has quickly scaled its presence, signed local clients, and begun laying the groundwork for further global expansion.

Here, Tradedoubler CEO Matthias Stadelmeyer talks through the realities of entering the US market, the company’s expansion plans for 2026, and how it’s approaching some of the industry’s biggest themes, from attribution in LLMs to transparency, fraud, and compliance.

Sol Wilkinson: So, first question, I wanted to ask about your US expansion. Last year, you opened your first US office in Miami.

Matthias Stadelmeyer: Yes.

SW: How’s business performed so far? 

MS: Business is developing well. We started the US business a bit before by launching programmes there, managed by the UK team. 

At the end of 2024, we had around 150 programmes live in the US, which was when we realised we really needed a local team on the ground; we were getting more market-relevant questions and requests. We launched the US office in May 2025. 

By the end of last year, we had around 250 programmes live in the US and Canada, so that’s a good uplift from the 150 we had. A good part of that is existing clients in Europe who have expanded into the US or Canada. But we were able to sign quite a few local clients as well, which for me was a breakthrough because that shows what you can do when you’re there.
