The Open-Source MMM Stack (Meta Robyn + Google Meridian + PyMC)
Meta Robyn, Google Meridian (2025), and PyMC-Marketing have democratized MMM — each framework runs on the customer's warehouse data, shifting value from the model vendor to the compute layer.
Scale
Industry-wide shift: Meta Robyn widely adopted; Google Meridian released 2025
Before
$200K–$500K vendor MMM studies; 3–6 month delivery; static PDF reports
After
Free open-source frameworks (Robyn, Meridian, PyMC) running on customer's own warehouse data — continuous and transparent
Key Insight
The model is free; the compute and data infra are the value — a direct opportunity for cloud warehouse vendors.
