Boris Cherny predicts AI will weaken traditional business moats. Switching costs decrease as AI can port systems, and process power is less defensible as AI can replicate complex workflows. However, foundational moats like network effects and scale economies will remain strong or grow in importance.

Historically, a deep library of integrations (like MuleSoft's or Rippling's) created a powerful defensive moat. Now, AI coding agents like Devin can replicate hundreds of integrations in a month at a very low cost, making this form of defensibility obsolete.

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.

Moats like migration pain, proprietary data, and UI lock-in are weakening. AI agents are flexible with interfaces and can easily replicate code and migrate data, forcing companies to find new, more distinct sources of value beyond simply 'owning' the customer.

The primary moat for many SaaS companies was the complexity and high cost of migrating away from their product. AI agents can now automate this process, eroding that advantage, increasing competition, and giving buyers significant leverage to renegotiate contracts.

The defensibility of large SaaS companies has been their position as the 'system of record' (e.g., the CRM database). AI agents, which can perform valuable actions and pull data from disparate sources, threaten this moat. Value may shift from the static database to the AI-driven process itself, upending the market.

Software's main competitive advantage isn't code, but its deep integration into customer data and workflows, creating high switching costs. AI threatens this moat by automating those integrated tasks, reducing customer stickiness and pricing power.

AI coding agents will make migrating between complex enterprise systems like SAP and Oracle dramatically easier and cheaper. This erodes the moat of high switching costs, forcing incumbents to compete on product value rather than customer lock-in, where they once held customers as "hostages."

Moats built around the sheer number of integrations or data connectors are vulnerable. AI coding assistants can now replicate this work in a fraction of the time, threatening incumbents like Salesforce and creating opportunities for new, nimbler challengers.
