Entrepreneurship studies often focus on firm growth-related topics. The factors affecting the high-growth (HG) in high-growth firms (HGFs) are not well established. While some studies suggest that proactive strategizing precedes the HG period, others consider that the near-random structure of the firm’s growth is better to delay growth-related investments. This study focuses on the “timing” of setting up new hierarchical layers and the consequences if it happens before or after the growth event.
