Focusing only on trendy sectors leads to intense competition where the vast majority of startups fail. True opportunity lies in contrarian ideas that others overlook or dismiss, as these markets have fewer competitors.

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.

Businesses with passionate but niche audiences, like the UFC or F1, can break into the mainstream by producing "on-ramp" content. A human-interest show (like F1's "Drive to Survive") provides an accessible entry point for new fans, demystifying the niche and driving massive growth by solving the discovery problem.

Contrary to the stereotype of unused luxury equipment, founders find home gyms to be consistently worth the investment. By removing the friction of traveling to a gym, they enable greater consistency and commitment to fitness, directly impacting long-term health more effectively than sporadic, intense efforts.

Instead of popular but saturated local services, focus on high-value, overlooked niches. Examples include smart home automation, closet organization, and garage renovation. These markets often have fewer competitors and high-value customers, presenting a significant opportunity.

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.

Instead of traditional market research tools, scrape Google Maps data. Analyze business listings, review volume, and sentiment to find niches with high customer demand but low satisfaction, signaling a clear market gap for a new or improved service.

Well-funded startups are pressured by investors to target large markets. This strategic constraint allows bootstrapped founders to outmaneuver them by focusing on and dominating a specific niche that is too small for the venture-backed competitor to justify.

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.
