Provenance

The term Agent Experience (AX) was coined by Mathias Biilmann (CEO, Netlify) in January 2025 — first at a Netlify all-hands, then publicly. He defined it as “the holistic experience AI agents will have as the user of a product or platform,” positioning it alongside UX and DX. He explicitly considered and rejected “Agentic Experience,” preferring “Agent Experience” for parity with User / Developer Experience. The “Agentic Experience” variant is widely used interchangeably by other authors. ax-go deliberately adopts “Agentic Experience” as its house term — the widely-used interchangeable variant — while noting that the originator’s preferred form is “Agent Experience.”
