about us

Calm Investments is an independent entrepreneurial investment firm that focuses on acquisitions and participations in small and midsized companies with a leading role in their market. We support entrepreneurs during a generation shift or with succession, helping them to make the next step in the company’s development. We invest with our own money in businesses that we believe in, allowing us to build long-term partnerships with the management of our companies.

At Calm Investments we have a team-based culture. We will collaborate based on transparency, integrity and mutual trust in our partnerships. We are committed to investing in leading, niche businesses with differentiated offerings.

We work together with the management of our companies as a committed partner. We will actively support our companies in areas such as strategy, data analytics, specific projects, operations and M&A. Our aim is to optimize our added values as a partner, either through a supporting role or through a leading role (when required).

Through collaboration, we provide both capital and operational resources. Examples of value adding support for our partners are:
