Gokul argues that brand is no longer a strong moat for B2B companies. As AI makes data portability and product replication easier, he predicts switching costs will approach zero, making business customers more rational and less loyal to brands.

The ability of AI agents to automate complex data migrations between platforms will significantly weaken "switching costs" as a competitive advantage for software companies. Businesses will need to rely more on other moats like network effects.

This business model embeds a vendor so deeply that a client's own institutional knowledge atrophies. The client's employees no longer understand critical business processes, making it prohibitively expensive and risky to switch vendors, who now hold all the expertise.

For subscription services, the most effective moat isn't the software itself, which can be replicated, but the accumulated user data. Users are reluctant to switch apps because they would lose years of personal history, stats, and community connections, creating strong lock-in.

Even if AI makes it easier to build competing software, incumbent SaaS giants retain customers due to immense switching costs. The operational disruption, retraining, and integration challenges of migrating a large organization create a powerful moat against new entrants.

Incumbent software like Workday creates immense stickiness, not through love, but through deep integration and high switching costs. This creates a 'Hotel California' effect where customers 'can check out any time they like, but they can never leave,' a moat that only a 10x better alternative can breach.

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.

True defensibility comes from creating high switching costs. When a product becomes a system of record or is deeply integrated into workflows, customers are effectively locked in. This makes the business resilient to competitors with marginally better features, as switching is too painful.

The most defensible businesses, especially in enterprise software, create such high switching costs that customers are essentially locked in. This "hostage" dynamic, where leaving is prohibitively difficult, is a stronger moat than simply having satisfied customers who could still churn. It's the foundation of an enduring software business.
