Sole proprietorships allow individuals to easily start and maintain control over small businesses. Several famous companies like eBay, Kinko's, Annie's Homegrown, Apple, Starbucks, McDonald's, and Virgin Records began as sole proprietorships, with founders like Pierre Omidyar, Paul Orfalea, Ann Withey, Steve Jobs, Howard Schultz, the McDonald brothers, and Richard Branson respectively starting their iconic brands as small, sole proprietor-run operations. These examples show how successful companies can grow substantially from humble beginnings under a sole proprietorship structure.
