The venture narrative focuses on 'slope' (rapid growth) but often misses the value of 'area under the curve' companies. These startups, like Figma, may have a slower growth story as they build deep moats. This long-term focus can create more durable value than high-slope businesses with weaker defensibility.

When Figma started, VCs deemed the designer market too small. While this made fundraising harder, it also meant fewer competitors rushed in. This perceived niche gave Figma the time and space to build a complex, defensible product before the market's true potential became obvious to everyone.

While low-capex businesses are easy to start, businesses requiring significant capital for equipment or technology create a financial barrier to entry. This reduces competition, allowing for more pricing power and long-term defensibility once you've achieved success.

Brand is becoming a key moat in AI infrastructure, a sector where it was previously irrelevant. In rapidly growing and confusing markets, education can't keep pace with adoption. As a result, customers default to the brands they recognize, creating powerful monopolies for early leaders. This mirrors the early internet era when Netscape dominated through brand recognition.

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.

Promote IQ succeeded by targeting large retailers, a market other startups avoided due to its notoriously difficult and long sales cycle. They turned this pain point into a strategic advantage. By mastering the difficult sales process, they created a high barrier to entry that gave them time and space to dominate the category before competitors could catch up.

True defensibility comes from successfully navigating successive challenges that weed out competitors. Many have an idea, fewer can build it, even fewer can maintain shipping cadence and distribution, and only a handful can raise capital at scale, leaving a 2-3 horse race.

Drawing from Verkada's decision to build its own hardware, the strategy is to intentionally tackle difficult, foundational challenges early on. While this requires more upfront investment and delays initial traction, it creates an immense competitive barrier that latecomers will struggle to overcome.

Defensible companies build systems of record (like an ERP) that are so integral to a customer's operations that switching is prohibitively difficult. This creates a 'hostage' dynamic, providing a powerful moat against competitors, even those with better AI features.
