We grow quietly and steadily – with a focus on quality, trust, and partnerships that last.

The company as it stands today was founded by the four partners who still run it: Torben Rasmussen, Jens Donslund, Michael Fjeldsted and Martin Bach.
Some may still know us as Juhlsen. The name has changed since, but we brought the experience and the way we work with us.
Today
Torben has worked with email marketing since it was new in Denmark. In 1999, he developed one of the first Danish email marketing systems at Atteno, used by many of the country's largest companies. Atteno was sold in 2007, and Torben continued as director until 2010.
That experience still shapes how Yulsn operates today. Technology must, of course, be able to do what's needed. But it only makes a difference when there's also time, budget, and skills to use it. That's why we don't just sell software – we help our customers every step of the way, so they can achieve more of their goals with the resources they have.
We go the extra mile for strong, loyal relationships. We value working at eye level with our partners and colleagues. We don't just build solutions – we follow up with genuine interest and aim for open, solution-oriented collaborations. We are:
We say it as it is – even when the answer is that something doesn’t make sense for you.
All customers should feel seen and heard. You get a dedicated contact person who knows you and your business.
We build what works in practice and lasts – not what looks best in a presentation.
We are curious about new opportunities, such as AI. But we only implement them when we can see that they create value for you.
Our work environment is built on trust and freedom. We value each individual's contribution and encourage authenticity. The relaxed atmosphere reflects in our customer interactions.
We have an office in Tranbjerg, but many of our colleagues work remotely – from Northern Jutland, to Zealand and even as far as Pleven in Bulgaria. Distance doesn't matter when you can rely on each other. And when we meet for team days, summer parties and Christmas lunches, everyone is an equally important part of the team.
Many of our colleagues stay with us for many years. Recently, two of our developers celebrated 10 years at Yulsn. For us, loyalty goes both ways: We highly value colleagues who take responsibility and insist on quality – and we do our best to create frameworks where there is also balance in everyday life for each individual. It is important.
