Headless SaaS
Software-as-a-service that operates without a traditional user interface, designed to be consumed programmatically by AI agents or other software via APIs. Mitchell Jones predicts that the dominant interface for SaaS in the agentic era is not a dashboard — it is an API endpoint that an agent can call on behalf of a user. Headless SaaS is the form factor that aligns with how autonomous agents work: they do not log in, they do not click buttons, they call endpoints. Companies that expose their value programmatically capture agent traffic; those that require human UI interaction do not.
