Established companies are businesses that have been operating for a significant period, often for several years or decades. They typically have a stable customer base, a well-defined brand, and a proven track record of profitability. These companies often have established processes and systems in place, which help them maintain efficiency and manage growth. Such companies can be found in various industries, including technology, manufacturing, and retail. Examples of established companies include Apple, Coca-Cola, and General Electric. Their longevity in the market often provides them with a competitive advantage, as they have built strong relationships with customers and suppliers over time.
