The Brief

The Brief is an AI marketing platform that runs the full advertising campaign lifecycle - discovering competitor and market signals, creating ads at scale, launching them across channels, and optimizing performance - through a system of four AI agents. Formerly the ad-design tool Creatopy, the company rebranded to The Brief in October 2025 to position itself as an 'AI agency' for in-house marketing teams and agencies, and reports nearly 10,000 brands using the platform.
