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.

Traditional SaaS switching costs were based on painful data migrations, which LLMs may now automate. The new moat for AI companies is creating deep, customized integrations into a customer's unique operational workflows. This is achieved through long, hands-on pilot periods that make the AI solution indispensable and hard to replace.

For EdTech startups, pivoting from D2C to B2B school sales is challenging, with long sales cycles. However, it creates a stickier business not subject to seasonal dips and, more importantly, provides equitable access to students in underserved communities, not just affluent families.

Unlike other models, a successful education business's goal is to make customers leave (graduate). To build a scalable business, founders must engineer "stickiness" through consumable components like communities, weekly research, or discount buying clubs that provide ongoing value beyond the initial course.

As the largest virtual school provider, Stride leverages its scale to offer free add-ons like tutoring for younger grades. Smaller competitors cannot afford these services, creating an "Amazon-ing effect" where the largest player can offer the most value, attracting more students and further enhancing its scale advantage.

An enterprise CIO confirms that once a company invests time training a generative AI solution, the cost to switch vendors becomes prohibitive. This means early-stage AI startups can build a powerful moat simply by being the first vendor to get implemented and trained.

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.

CIOs report that the unbudgeted 'soft costs' of implementing AI—training, onboarding, and business process change—are the highest they've ever seen. This extreme cost and effort will make companies highly reluctant to switch AI vendors, creating strong defensibility and lock-in for the platforms chosen during this initial wave.

The business is highly insulated from economic cycles. K-12 education is a mandatory, government-provided service. State funding per pupil has historically risen even during recessions, like the 2008 financial crisis. This makes Stride's revenue stream stable and predictable, akin to a utility.
