With the gradual disappearance of third-party cookies and the limitations of current tracking techniques, advertisers can no longer rely on attribution only to shape their media budgets. As a result, MMM has become essential once again. But while this methodology has traditionally been complex, static, expensive, and opaque, the MMM landscape is being reshaped by the arrival of new solutions on the market, from open-source MMMs like Google’s Meridian to agent-based models like fifty-five’s Digital Twin. fifty-five, one of the first companies to have tested Meridian and become Meridian-certified, invites you to discover the capabilities of this new tool, its potential to democratize MMM, and the results of its initial deployments in business settings.  Atteedees will also explore how the most advanced MMMs are using virtual agents for highly granular media and marketing management. ### **SCHEDULE** **4 PM** — Welcome **4:30 PM - 6 PM —** Conferences An afterwork session on Marketing Mix Modeling solutions and Meridian — Google’s newest tool for managing and measuring performance across channels. 1.
