Unattractive or morbid business ideas, such as cemetery management software, often face less competition. This lack of saturation means entrepreneurs willing to enter these "grim" niches have a higher probability of financial success and market capture.

Horizontal SaaS companies fracture their customer knowledge across diverse industries, forcing generic messaging. Vertical SaaS companies build compounding knowledge with each customer within a niche. This leads to deeper insights, stronger competitive secrets, and more effective, specific messaging over time.

Analyzing over 200 investments, TinySeed observed that vertical SaaS companies consistently achieve stronger exits, grow further, and have lower churn than horizontal SaaS. This data-driven insight has shifted their investment thesis toward more defensible, niche-focused companies, as they have proven to have distinct advantages.

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.

Don't overlook seemingly "boring" industries like cybersecurity or compliance. These sectors often have massive, non-negotiable budgets and fewer competitors than glamorous, consumer-facing markets. Solving complex, high-stakes problems for large companies is a direct path to significant revenue.

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.

Neither of Vantaca's co-founders were software engineers by trade; they were an electrical and a nuclear engineer. One brought deep industry expertise while the other focused on strategy and growth. They succeeded by deeply understanding the customer's problem and hiring technical talent, showing domain knowledge can be more critical than coding ability in vertical SaaS.

YC Partner Harsh Taggar suggests a durable competitive moat for startups exists in niche, B2B verticals like auditing or insurance. The top engineering talent at large labs like OpenAI or Anthropic are unlikely to be passionate about building these specific applications, leaving the market open for focused startups.

Despite 70% of the market being controlled by HOAs, the advice is to focus on "scatter" individual homes. The HOA market is an auction where the lowest bid wins, destroying margins. By focusing on individual homeowners, the business can control its pricing, maintain higher margins, and avoid a race to the bottom.
