Show HN: Spendict – a performance marketer's verdict for AI agents, over MCP (www.spendict.com)

Spendict, a new platform designed for performance marketers, offers a groundbreaking approach to ad spending by providing deterministic verdicts on advertisements—run, fix_first, or kill—before any budget is allocated. This innovative feature allows marketers to cut ad spend leaks within 30 days, ensuring that only ads that meet specific performance criteria are funded. The platform leverages input from experienced marketers with over a decade in paid social, using real ad data to calibrate its verdicts, thus transforming how companies manage their customer acquisition costs (CAC). The significance of Spendict lies in its potential to optimize advertising strategies while minimizing waste. By integrating seamlessly with existing tools via its CLI or REST APIs, Spendict enables users to receive instant evaluations of ad performance metrics, including audience fit and compliance with platform rules. This approach not only streamlines budget allocation but also aids in the identification of creative fatigue compared to structural problems. As advertising costs rise—such as a reported 34% increase in Meta CPMs—tools like Spendict provide marketers with the confidence to scale their ad spend intelligently, ultimately aiming to drive higher returns and efficiency in campaigns.
