Courage for growth, international expansion and change

We are the right partner when a company’s business or ownership is going through changes.
Juha Tukiainen, Managing Partner

MB Funds is a Finnish private equity firm that invests mainly in mid-sized enterprises in Finland. Our mission is to create sustainable growth with our investee companies as well as profitable and responsible results for our investors. We are the perfect partner when a company’s ownership or business is going through changes.

The cornerstones of our approach are responsible ownership, trust-based partnerships and productive cooperation. Returns on the investment come when the company is sold to a new owner, usually 3-7 years after the investment.

MB Funds as an investor and a partner

The main principles of MB Funds are based on commitment and partnership. Our strengths include many years of experience and an open mind which can be seen in our adaptive operating models. We believe that management and other key personnel are vital to the success and development of any company. Openness and trust are our guiding principles. We are a responsible owner and offer innovative solutions in evolving business situations.

The investments are made through our private equity funds. Our investors mainly consist of pension institutions from Finland and other Nordic countries. By increasing the value of the investments, we contribute towards the financing of the pension system. We currently manage private equity funds of approximately 500 million euros in total.

Our extensive experience has helped define the three phases of our operating model. As a whole, the investment period usually takes 3-7 years. In each phase of the investment process, we emphasise open cooperation, clearly defined roles between all parties and ambitious growth.


Investment – planting the seed of success

The investment phase creates the right environment for the company’s success during the entire investment period. Before making an investment, we plan the growth strategy together with the company management in order to implement this strategy together.

The due diligence phase preceding this phase helps us understand the strengths of the company and to familiarise us with its management and key personnel.

Growing company value – development and growth

As an active and committed owner, we participate in the implementation of the business strategy through board work and cooperation. Each investee company is assigned a person responsible for nurturing such cooperation throughout MB ownership. We seek experienced professionals to serve on the board to bring in expertise for implementing the strategy.

We support the operating management in executing the jointly agreed business plan. There is a clear division of responsibilities between MB and corporate management. The management executes the business plan and is in charge of the day-to-day running of the company. MB participates in developing and executing the strategy through the board of directors and acts as a discussion partner. We provide the leadership with sufficient resources and incentives to build a successful business.

We promote the growth and development of the company through professional board work, developing reporting systems and reinforcing management best practices and good corporate culture.

Exit – the harvest

The MB Funds investment model means that our ownership lasts for a limited period. Once the planned development goals are reached, it is time to gather the harvest and exit the company. A successful exit means substantial earnings for the company owners and investors.

At the end of the ownership period, the company is usually sold to an industrial buyer or a larger private equity investor. The exit strategy can also be listing on the stock exchange and the sale of shares. Usually the chosen exit strategy will be decided based on the company’s future potential to pave the way for the next strategic phase of development.

Sustainability at MB

We are committed to integrating environmental, social and governance aspects (ESG) in our investment strategy. We see our sustainability approach divided into three parts: responsible investment, impact, and transparency and disclosure.

Implementing and developing the sustainability of our operations is handled by our sustainability and communications manager Minna Heimonen.
