Summary
On this week's episode of the podcast, I am joined by Michael Kaminsky , co-founder and co-CEO of Recast . We explore the rise of open-source Marketing Mix Modeling (MMM) tools and the challenges of measuring modern ad spend. Among other things, we discuss: Whether open-source MMM libraries like Robyn and Meridian are truly unbiased tools or subtle instruments for big tech self-grading How marketers can effectively evaluate the accuracy of MMM outputs through techniques like parameter recovery and predictive forecasting Why smaller, performance-driven brands might actually find more value in last-touch attribution than in complex econometric modeling If the inherent uncertainty in MMM estimates makes them fundamentally incompatible with the fast-paced feedback loops of digital advertising What role generative AI and large language models play in democratizing access to sophisticated marketing data science analysis When a brand should transition from simple attribution methods to a multi-layered approach involving incrementality and econometric modeling How the shift toward CTV and non-trackable channels is forcing a resurgence in probabilistic measurement frameworks like MMM Thanks to the sponsors of this week’s episode of the Mobile Dev Memo podcast: INCRMNTAL .
