Large companies often focus R&D on high-ticket items, neglecting smaller accessory categories. This creates a market gap for focused startups to innovate and solve specific problems that bigger players overlook, allowing them to build a defensible niche.

Flock Safety was dismissed by VCs because its initial market of neighborhood associations seemed too small. This perception of a small TAM acted as a moat, deterring competition and allowing them to build a foundation to later expand into much larger government contracts.

Figma's market initially seemed too small to attract major VC interest or intense competition, giving them space to build a defensible product. Founders can gain a significant advantage by working in overlooked spaces, provided they have genuine passion to sustain them for a decade or more.

Large platforms focus on massive opportunities right in front of them ('gold bricks at their feet'). They consciously ignore even valuable markets that require more effort ('gold bricks 100 feet away'). This strategic neglect creates defensible spaces for startups in those niche areas.

Don't fear competitive "red oceans"; they signal huge demand. The winning strategy is to start in an artificially constrained niche (a puddle) where you can dominate. Once you're the biggest fish there, sequentially expand your market to a pond, then a lake, and finally the ocean.

Top compounders intentionally target and dominate small, slow-growing niche markets. These markets are unattractive to large private equity firms, allowing the compounder to build a durable competitive advantage and pricing power with little interference from deep-pocketed rivals.
