Seema Amble argues that in an agentic, headless era, defensibility moves from UI-driven stickiness to the data model, permissions, workflow logic, and real-world execution that undergird a system of record. The piece shows how reliance on the UI historically created data hygiene and context, but agents bypass interfaces and expose data directly, making migrations hard due to undocumented SOPs, deep dependencies, and compliance needs. It outlines three strategic paths for buyers—augment incumbents with agent interfaces, DIY rebuild, or buy AI-native replacements—and highlights defensibility criteria for the future, including recreating the SoR, owning proprietary data, closing the action loop, and enabling real-world execution connectivity.
