As a property manager, you can see where the work could be done better. But there is a long way from spotting a problem to being able to change the system you work in yourself.
That is how Kasper describes the day-to-day experience that led him to choose Rumli as Blomfelt’s future. Blomfelt is Rumli’s fourth acquisition in 2026, following Hegnsholt Ejendomsadministration, SAPU and Sofus Administration.
A growing business
Kasper has been managing director of Blomfelt since 2021 and has worked in the industry since 2004. Blomfelt manages approximately 140 owners’ associations, cooperative housing associations, homeowners’ associations and shared courtyard associations in Copenhagen, representing around 3,500 units.
The business has grown quickly in recent years. In October 2024, Blomfelt acquired CEA Administration, with approximately 90 management agreements and five employees. Revenue grew by around 160 per cent from 2023 to 2025. That growth has also strengthened Kasper’s wish to bring more resources and expertise together for the next stage.
We have built a business with skilled colleagues, close customer relationships and ambitions to become much bigger. The next step requires technology, capital and more expertise, says Kasper.
Why Rumli
Kasper was contacted by Rumli, which shared his ambitions and could bring something Blomfelt did not have on its own. Rumli was started by the team behind Proper, which has spent nine years developing software for landlords and property managers. At Rumli, property managers and developers work in the same company.
That is one of the things I find most interesting about Rumli. We can bring our experience directly into development and have a say in what the tools need to do, he says.
With Blomfelt, Rumli gains a team that specialises in associations and has many years of experience working with boards, general meetings and building projects.
Kasper and the team at Blomfelt have built one of the most ambitious association management businesses in the country. They know the boards and understand what it takes to give them sound advice. Together, we want to give associations even better management, says Morten Krarup of Rumli.
The same faces, a new platform
Blomfelt is now a Rumli subsidiary, with Kasper continuing as managing director. Customers keep the same contacts, and all employees are staying with the business.
Over the coming months, Blomfelt will move its daily work onto Rumli’s platform, and the team will move into the same office as Rumli.
The aim is to bring information together and automate more of the repetitive preparation. When a board needs advice on a building project, for example, the property manager should spend less time finding documents and more time assessing the case and helping the board move forward.
I want to give my colleagues better opportunities to use their professional expertise. That is good for employees, good for customers and a strong basis for developing the business, says Kasper.
Rumli expects to acquire several more property management businesses over the next 12 months. The ambition is to build a leading Danish property management business, with each new company contributing experience and expertise to its development. Kasper believes many owners will recognise the wish to develop their business while taking care of what they have built.
If others are considering the same things, I would be happy to have a conversation about why we chose this path, he says.
