Startups often fail to displace incumbents because they become successful 'point solutions' and get acquired. The harder path to a much larger outcome is to build the entire integrated stack from the start, but initially serve a simpler, down-market customer segment before moving up.
Initial data suggested the market for design tools was too small to build a large business. Figma's founders bet on the trend that design was becoming a key business differentiator, which would force the market to expand. They focused on building for the trend, not the existing TAM.
Contrary to the belief that a moat always leads to large-cap status, small-cap moats often protect a profitable niche. The moat provides time and protection for management to operate, but the "castle" itself may have a limited growth runway, focusing on returns within a specific market.
A smaller fund size enables investments in seemingly niche but potentially lucrative sectors, such as software for dental labs. A larger fund would have to pass on such a deal, not because the founder is weak, but because the potential exit isn't large enough to satisfy their fund return model.
Instead of a broad launch, Everflow targeted only mobile affiliate networks—a small market they knew deeply from their previous company. This allowed them to build very specific, high-value features for that ICP, win deals, and establish a strong beachhead before expanding into larger, adjacent markets.
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.
Palo Alto Networks pursued cloud cybersecurity when experts claimed no one would trust it. Founder Nir Zook saw this skepticism not as a warning, but as a sign of a wide-open market with a significant competitive moat if they could prove the doubters wrong.
This provides a simple but powerful framework for venture investing. For companies in markets with demonstrably huge TAMs (e.g., AI coding), valuation is secondary to backing the winner. For markets with a more uncertain or constrained TAM (e.g., vertical SaaS), traditional valuation discipline and entry price matter significantly.
