Celltech's roots date back to 1989. Engineer Matti Öhman and Hannu Hietala established Insmat Oy after finding out that there was demand for different types of battery packs. With the rise of cellular phones in the 1990s, the company's operations took off. At that time, the company began including cellular phone batteries and accessories in the product range.
For over 25 years, the desire to develop and improve has transformed a small, local business into an international operator that has offices in Finland, Sweden, Norway and Denmark. Our customer base has expended from the Nordic countries to cover the entire world.
Celltech is owned by the Stockholm Stock Exchange-listed Addtech AB; Addtech's history dates back over a century. Addtech supports Celltech by providing expanded production capacity and partners in Sweden and China. Together with our affiliates we are the clear market leader and largest operator in the Nordic countries.
