Swivel

What its AI agents do: Swivel’s AI agents automate ad monetization for publishers, performing up to 50,000 optimizations per day, compared to the 100–200 typically handled by human ad ops teams. Through a rules-based engine, publishers first set parameters for tasks like line item creation, which the AI then automates. The agents also surface strategic recommendations where, if a publisher sets a rule, such as adjusting price floors based on performance, the AI agent can analyze similar patterns across other demand partners and suggest expanding that logic to optimize yield.
