Company size refers to the scale of a business, typically categorized by the number of employees or annual revenue. Businesses are often classified as small, medium, or large. Small companies usually have fewer than 100 employees, while medium-sized companies may have between 100 and 999 employees. Large companies often employ 1,000 or more individuals. The size of a company can impact its operations, culture, and market influence. For instance, larger companies like Apple or Amazon may have more resources for research and development, while smaller firms might be more agile and innovative. Understanding company size helps in analyzing business strategies and market dynamics.
