Betsson Group is one of Europe’s largest iGaming companies, operating more than 20 brands across 20+ countries. With thousands of employees and a fast-moving industry to stay ahead of, the company has always made developer excellence a priority.
As their teams continued to grow, Betsson began looking for ways to make onboarding new developers and closing skills gaps faster and make code quality more consistent. It was not about fixing a problem, but about making sure their engineers could be productive quickly while senior staff focused on the projects that mattered most.
“The main thing is you have to spend lots of time with new staff. This means money. The cost of this is obviously more than what Dometrain would be.”

Betsson’s first encounter with Dometrain came through Nick Chapsas’s YouTube videos. Once they explored the full platform, the decision was clear.
Unlike other providers they had tried in the past, Dometrain offered:
“I haven’t found any other platforms that can do this. Building applications that handle traffic, scale, and remain maintainable is the hard part, and Dometrain gets that right.”

The value also resonated with leadership:
“If you look at the price for the Dometrain subscription, it’s pretty much the same as taking them out for a meal once a month.”
The rollout was smooth, and the adoption across teams was enthusiastic.
The results were immediate.
When Betsson needed to refactor their GitHub Actions setup under a tight deadline, one developer relied on Dometrain’s GitHub Actions course. The training gave him the confidence and knowledge to deliver the project successfully, avoiding delays and potential production risks.
“If we didn’t meet that deadline or if anything went wrong in production, it would have been a huge problem. This course helped us make sure we got it right the first time.”
Onboarding time for new developers was significantly reduced. By giving each new hire access to targeted courses, Betsson shortened the ramp-up period from months to weeks.
Beyond speed, Dometrain improved team dynamics:
Betsson has gone beyond using Dometrain as a training tool. It is now built into the way the company develops its people.
“It’s exactly what was missing from this community, especially for .NET developers. But the biggest surprise was that it covers our entire tech stack. No one could have expected that when we bought the license.”
Betsson’s experience shows that when a company invests in the right training, the benefits go far beyond onboarding. With Dometrain, they have been able to:
“The highlight is that we’re applying practical learnings in our day-to-day jobs. That’s it. It’s exactly what we’re working on, not nice to haves.”
For Betsson, Dometrain is more than a training platform. It is a strategic asset that helps their teams move faster, collaborate better, and stay future-proof in a competitive industry.
