As AI accelerates technological progress and shortens relevance cycles, traditional tech moats become less defensible. However, network effects—especially in complex, fragmented marketplaces—remain a powerful and durable advantage. An AI agent cannot be simply prompted to "create a network effect."

In the AI era, where technology can be replicated quickly, the true moat is a founder's credibility and network built over decades. This "unfair advantage" enables faster sales cycles with trusted buyers, creating a first-mover advantage that is difficult for competitors to overcome.
In the fast-evolving AI space, traditional moats are less relevant. The new defensibility comes from momentum—a combination of rapid product shipment velocity and effective distribution. Teams that can build and distribute faster than competitors will win, as the underlying technology layer is constantly shifting.
AI capabilities offer strong differentiation against human alternatives. However, this is not a sustainable moat against competitors who can use the same AI models. Lasting defensibility still comes from traditional moats like workflow integration and network effects.
The long-held belief that a complex codebase provides a durable competitive advantage is becoming obsolete due to AI. As software becomes easier to replicate, defensibility shifts away from the technology itself and back toward classic business moats like network effects, brand reputation, and deep industry integration.
As AI makes building software features trivial, the sustainable competitive advantage shifts to data. A true data moat uses proprietary customer interaction data to train AI models, creating a feedback loop that continuously improves the product faster than competitors.
As AI commoditizes technology, traditional moats are eroding. The only sustainable advantage is "relationship capital"—being defined by *who* you serve, not *what* you do. This is built through depth (feeling seen), density (community belonging), and durability (permission to offer more products).
Despite its massive user base, OpenAI's position is precarious. It lacks true network effects, strong feature lock-in, and control over its cost base since it relies on Microsoft's infrastructure. Its long-term defensibility depends on rapidly building product ecosystems and its own infrastructure advantages.
As AI commoditizes business execution, true defensibility will come from creative ingenuity in areas like go-to-market strategy or novel business models. This form of creativity cannot be generated by AI, making it a rare and durable competitive advantage.
While startups like OpenAI can lead with a superior model, incumbents like Google and Meta possess the ultimate moat: distribution to billions of users across multiple top-ranked apps. They can rapidly deploy "good enough" models through established channels to reclaim market share from first-movers.
New technology like AI doesn't automatically displace incumbents. Established players like DoorDash and Google successfully defend their turf by leveraging deep-rooted network effects (e.g., restaurant relationships, user habits). They can adopt or build competing tech, while challengers struggle to replicate the established ecosystem.
