Premix Management

A successful company is made of people who feel good about the work they do

Premix is a family-owned company whose history dates back to the 1980s. The founder of our company, Antti Kiikka, still sits at the Premix Board while his daughter, Hanna Ristola, now runs the company. Hanna’s brother, Tuomas Kiikka, heads Premix's New Business Development.

We are strongly developing our operations and our industry. In our vision, we have defined that our sales revenue is increasing by more than 10% a year. We believe that a successful company is based on inspired people who feel good about the work they do. We guarantee this by making sure that our people are well led and empowered. Thus, we put a strong emphasis on our leadership processes and coaching skillfulness.

Premix Board

Although we are a family-run company, we have found that a Board consisting of professionals also outside the industry brings much value to our operations. The Board is very energetic and inspires all of us for growth. New innovative ideas emerge at each board meeting. Antti Kiikka, Premix founder acted as Chairman of the Board for decades, but in April 2017 Kalle Reponen was chosen as the next Chairman of the Board. Other Board members are Mika Toikka, Lars Gädda, Antti Kiikka, Hanna Ristola, and Tuomas Kiikka.

I am happy to run a company with huge growth targets and potential. Our team of dedicated, enthusiastic experts just keeps getting bigger and better! In addition to technical expertise and know-how, we value the good chemistry between people. At Premix, we are dynamic, passionate and full of laughter and appreciation towards one another. We are committed to a first-class customer experience and cherish our values that are not only words on the wall – we live them true every day.
