As AI commoditizes user interfaces, enduring value will reside in the backend systems that are the authoritative source of data (e.g., payroll, financial records). These 'systems of record' are sticky due to regulation, business process integration, and high switching costs.

Jerry Murdock argues the value of systems of record is tied to their ecosystem. If AI agents create new workflows that bypass these platforms, or if the companies built upon them fail, these systems degrade into simple databases, regardless of the data they hold. Their moat is workflow integration, not data.

The value in software is shifting from SaaS platforms (like CRMs) to the AI agent layer that automates work on top of them. This will turn established SaaS companies into simple data repositories, or "hooks," diminishing their stickiness and pricing power as agents can easily migrate data.

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.

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.

With AI agents in platforms like ChatGPT becoming the primary work surface, the traditional SaaS moat of owning the user interface is eroding. The most defensible position will be owning the core data as the "system of record," making the SaaS platform an essential backend database.

Incumbent SaaS companies like Salesforce are cutting off API access to prevent AI startups from siphoning value. To build a durable business, new AI companies cannot simply be a "system of action" on top of old platforms; they must aim to become the new system of record, which requires building complex data migration tools from day one.

To combat the threat of being disintermediated by AI agents, SaaS "systems of record" like HubSpot are planning to charge for third-party access to customer data. This move is a strategy to create a new revenue stream and avoid becoming a free, commoditized data pipeline for other companies' AI tools.

The threat of AI to SaaS is overstated for companies that own either a deep relationship with the user or a critical system of record. "Glue layer" SaaS companies without these moats are most at risk, while those like Salesforce (owning the customer relationship) are more durable.
