About us

The story

Mertala Innovations Oy is an engineering company founded in 2009 in Sulkava by Asko and Olli Toropainen. That year, after Asko graduated as an engineer from the Jyväskylä University of Applied Sciences, there was little job supply during the recession, and the desire to return to his home region gave him the spark to employ himself. Mertala Innovations Oy began as a producer of engineering services supporting the operations of the machine workshop Rautaseiska Oy. The original business idea was to refine our customers' ideas into innovations.

Over time and as the customer base expanded, the operation developed more from project deliveries of unique machines to the production of contract-based design services. In 2018, Asko got to know Akseli Kärkkäinen while working in a shared office at the client's premises. After three years of successful co-operation, a business arrangement was made, as a result of which Akseli became the company's co-owner and chairman of the board.

Today, our company offers mechanical engineering, 3D scanning services, and after Janne Savolainen joined the company from the beginning of 2022, also strength calculation and other technical calculation expert services. We also co-operate closely with the machine workshop Rautaseiska Oy in terms of machine building, manufacturing various individual machines and prototypes as project deliveries. Our premises are located in Lappeenranta and Sulkava.
