Tången’s business areas

We own to
develop – long-term and profitably

Tången owns platform companies and niche companies within selected industries and business areas – where we have deep knowledge, experience, and the ability to make a difference. Today, we operate within three business areas and are the main owner in companies with a history of profitability and healthy cash flows. This provides a solid foundation for long-term and resilient growth.

All our investments follow clear criteria and are made within the framework of our business areas. Through active ownership, we help already strong companies continue to grow – in a structured, profitable, and sustainable way.
