The growth of firms is a complex but relevant subject for different stakeholders, such as owners, who want returns on their investment, and society, where firms are vessels for jobs and job creation. Despite the vast amount of research conducted on firm growth and factors associated with firm growth, there is no coherent body of knowledge, and the average firm is not growing.This research focuses on growth in established small and medium-sized enterprises (SMEs), i.e. firms that have passed the startup phase and have established themselves on the market. The purpose is to investigate the characteristics of high-growth established SMEs with special focus on the entrepreneur's growth ambitions and the role of innovation activities for firm growth.The data was collected from 88 established SMEs in which interviews were conducted with CEOs, owners, managers, and employees. A questionnaire was used which included questions regarding factors previously linked to firm growth such as resources, market factors, organizational factors, innovation, and attitude toward firm growth.The results show that growth ambitions have a limited impact on firm growth, and that growth ambitions alone are not a good predictor of firm growth. When high-growth firms were compared to the average established SME, there was no difference in the level the managers of the firms were seeking growth. Neither lack of growth, nor high growth, can be explained by the managers' perception of the firm's possibility to grow. Furthermore, there is no evidence that the difference in growth rates is attributed to different levels of growth opportunities.Instead, this research shows that what distinguishes high-growth firms from the average, nongrowing firms are factors associated with innovation, the market, and customer knowledge. The high-growth firms were found to be significantly better at identifying and delivering on unfilled demands. However, no evidence suggests that the high-growth firms had exclusive access to new technology they could leverage as a means to grow faster, and both groups believed there to be plenty of market opportunities and possibilities to create growing niches.If the difference between high growth and no growth in established SMEs is associated with external factors related to innovation, market and customers, it is interesting that when growth ambitions increase, so does the internal focus on organizational structures and systems.Ambitious entrepreneurs who seek firm growth should therefore not lose sight of external factors, and strive to quickly deal with increased internal complexity that accompanies firm growth.iii Istället visar denna studie att det som särskiljer snabbväxande etablerade SMF från genomsnittliga, icke växande, företag är faktorer knutna till innovation, marknad, och företagens kunskap om sina kunder. De snabbast växande företagen var betydligt bättre på att identifiera nya krav och utnyttja den efterfråga som fanns. Noterbart är att de snabbväxande företagen inte hade exklusiv tillgång till ny te...

In a study of 409 Swedish SMEs, the difference between the highest growing, which can be characterized as gazelles, and the lowest growing companies were examined regarding performance change over a four year period and what contributed to the growth from an innovation perspective. It was concluded that, besides growing, the highest growing companies also showed high profitability,increased number of employees, and significantly higher markets shares locally, nationally and internationally than the lowest growing companies. Several traits were found to contribute to this. The highest growing companies had a significantly higher portion of new products as part of the turnover during the four years studied and they perceived themselves as differentiating from their competitors concerning: (1) offering better products, (2) understanding customer needs better, (3) having a higher pace or being more agile, and (4) keeping costs down. They also found it more important to take risks, reinvest any profit, and to focus on growth than the lowest growing companies, and this regardless of industry.
