# AI agent for marketing

> An AI agent for marketing is a system given a commercial objective, tools such as a warehouse, models and execution channels, and the autonomy to decide which actions best serve that objective. Decisioning agents read signals, propose hypotheses, size opportunities, choose actions and measure each against a control group.

## Why it matters for ARPU

Markin runs the analytical loop as agents rather than as a campaign calendar, which is what raises decision volume without lowering the evidential standard behind each decision.
