AI may be reshaping media planning and buying, but not every business problem requires an AI solution. In this episode of Media Monitor: Conversations at Cannes, Guideline Chief Product Officer Steve Silvers speaks with Drew Kane, Chief Product Officer for Prisma at Mediaocean, about media workflow automation, agentic buying, and why trusted systems of record become even more valuable as machines make more decisions. The conversation begins with Prisma’s role as a financial, contractual, and workflow system supporting the media industry from planning through payment. Drew explains how Mediaocean’s wider portfolio—including Prisma, Innovid, and Protected Media—helps agencies and advertisers manage creative workflows, buying, verification, and financial accountability. Steve and Drew then discuss the new integration between Guideline’s MediaTools and Prisma. While information has moved between the two platforms for years, the new API integration reduces manual work and helps keep planning and execution data synchronised. Objectives and budgets can flow more directly from MediaTools into Prisma, with actualised results moving back through the workflow. The result is less friction, fewer manual errors, and more time for teams to focus on business outcomes. Their discussion then turns to AI. At Cannes, many companies are trying to apply AI to nearly every workflow. Drew argues for a more disciplined approach: begin with the business outcome, then choose the appropriate technology. Sometimes that means an AI agent. Sometimes it means an MCP-enabled workflow. And sometimes a deterministic API is still the better answer. Steve and Drew also examine the emerging world of buyer and seller agents, where systems could identify inventory, exchange campaign requirements, and accelerate media transactions. But as the number and speed of automated decisions increase, so does the need for governance. Someone still has to track what was approved, where the money went, what changed, and whether the advertiser received the expected value. That is where systems of record become essential.
