The New Software Stack reveals a structural pattern: value is concentrating at two extremes of the stack while the middle gets cannibalized. We call this The SaaS Hourglass.
Top of the stack (orchestration): Platforms that control how agents coordinate, execute, and deliver outcomes. The Conductor, The Platform State, and The Bounty Model from the SaaS Value Migration Map.
Bottom of the stack (data): Companies with proprietary data assets, knowledge graphs, and semantic infrastructure. The Memory and The Substrate.
What Gets Hollowed Out
The middle layer — UI-dependent workflow applications, dashboard tools, manual process software — faces structural cannibalization. These are the companies that the Value Migration Map places in the Seat Tax and Modular Factory quadrants.
Why? Because agents bypass interfaces entirely. A projectmanagement tool’s value was in the dashboard humans navigated. When an agent orchestrates tasks directly through APIs, the dashboard becomes irrelevant. The data underneath and the orchestration above capture all the value.
The Practical Test
Ask this question about any SaaSproduct: “If an AI agent could do this job, would it need to see the interface?”
If yes — value is in the data or orchestration layer. The interface is just a window.
If no — the interface IS the product, and it’s vulnerable to displacement.
Most mid-market SaaS fails this test. The MongoDB case study shows even database companies aren’t immune — the question is whether your data layer has proprietary advantages or is interchangeable commodity infrastructure.
