Gorilla, Chimp, Monkey

In The You On AI Field Guide

The gorilla's advantage is compounding. Once a company achieves de facto standard status, network effects, switching costs, and ecosystem gravity reinforce the position. Developers build for the gorilla's platform because that's where users are; users adopt the gorilla's platform because that's where developers build. The chimp must overcome this compounding advantage with differentiation that matters enough to justify the switching costs, which is structurally difficult.

Chimps typically survive by serving segments where the gorilla's standard doesn't fit perfectly — specific industries, specific use cases, specific geographies. They operate as competitive pressure on the gorilla without displacing it. Monkeys survive by avoiding direct competition entirely, finding niches the gorilla has no interest in serving and no ability to serve well given its scale-oriented economics.

In the AI landscape, the gorilla contest is unusual because the capability gap between frontier models is narrow and the differentiation vectors are multiple (coding, reasoning, multimodal, safety, agentic behavior). This produces a more complex competitive landscape than the traditional single-gorilla pattern — possibly a multi-gorilla equilibrium where different providers dominate different segments, or possibly a single-gorilla outcome on a longer timeline.

The Geoffrey Moore — On AI volume uses this framework to map the competitive structure of AI developer tools, consumer AI, and emerging enterprise AI categories. The underlying strategic question for each segment is the same: who will establish de facto standard status, how will that status be contested, and what does the equilibrium look like once the tornado subsides?

Origin

Moore developed the framework through his consulting practice and formalized it in Inside the Tornado (1995) and The Gorilla Game (1998, with Paul Johnson and Tom Kippola). The framework was designed partly as an investment thesis — identifying likely gorillas during the tornado phase was the book's investment strategy.

Key Ideas

Gorillas capture disproportionate value. Network effects, switching costs, and ecosystem gravity reinforce the standard position.

Chimps survive through differentiation. They hold smaller positions by serving segments the gorilla's standard doesn't fit.

Monkeys avoid direct competition. They find niches the gorilla won't or can't serve.

The tornado decides gorilla position. Distribution velocity, not capability, determines which company captures standard status.

Post-tornado equilibrium is stable. The gorilla's position reinforces until the next disruption resets the cycle.
