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.

While AI can easily replicate simple SaaS features (e.g., a server alert), it poses little threat to deeply embedded enterprise systems. The complexity, integrations, and "dark matter" of these platforms create a "hostage" dynamic where ripping them out is impractical, regardless of cloning capabilities.

MongoDB's CEO argues that AI's disruptive threat to enterprise software is segmented. Companies serving SMBs are most at risk because their products are less sticky and more easily replaced by AI-generated tools. In contrast, vendors serving large enterprises are more protected because "products are always replaceable, platforms are not."

Established SaaS companies can defend against AI disruption by leaning into their role as secure, compliant systems of record. While AI can replicate features, it cannot easily replace the years of trust, security protocols, and enterprise-grade support that large companies pay for. Their value shifts from UI to being a trusted database.

AI agents can easily siphon off value from SaaS products priced on per-seat utility by automating tasks previously done by humans (e.g., support tickets). In contrast, deeply embedded systems of record (ERP, CRM) are insulated by career-limiting switching costs and the immense challenge of migrating timeless, critical data.

SaaS value lies in its encoded business processes, not its underlying code. AI's primary impact will be forcing SaaS companies to adopt natural language and conversational interfaces to meet new user expectations. The backend complexity remains essential and is not the point of disruption.

To gauge AI's true impact on SaaS giants, ignore their slow-to-change enterprise customers. Instead, analyze the adoption patterns of new, small companies. If startups are skipping established SaaS platforms for AI tools, it signals a bottom-up disruption that will eventually reach the enterprise.

Nimble small and medium-sized businesses will increasingly use AI to build custom internal tools, especially for CRM. They will opt to create the 20% of features they actually need, rather than pay for complex, expensive enterprise software where they ignore 80% of the functionality.

The existential threat from large language models is greatest for apps that are essentially single-feature utilities (e.g., a keyword recommender). Complex SaaS products that solve a multifaceted "job to be done," like a CRM or error monitoring tool, are far less likely to be fully replaced.
