The report examines the dynamics of company size classes in Finland and the relationship between growth barriers and company size. It finds that companies tend to move towards larger size categories rather than growing, with the majority staying in the same size category for three to five years. The main growth barriers faced by companies are heavy regulation and a desire to avoid debt. However, there are differences among different size categories, with micro-enterprises experiencing more growth barriers due to a lack of sales and marketing capabilities. Medium-sized companies face more competition-based growth barriers due to higher costs. The Mittelstand category faces the least growth barriers.
