Google Meridian
Google Meridian is an open source Marketing Mix Modeling (MMM) framework built by Google to help advertisers and analysts accurately measure the impact of their marketing efforts across online and offline channels without relying on cookies or user-level tracking. At its core, Meridian uses a Bayesian causal-inference model that can ingest aggregated data (spend, sales or KPI outcomes, reach/frequency, geo-level data, seasonality, and external controls) to estimate the incremental contribution each marketing channel (e.g., search, social, video, offline media) makes to overall performance, and compute return on ad spend (ROAS), response curves, and optimal budget allocation. Because it’s open source, users have full transparency into methodology and code, giving them control over model configuration, data inputs, and assumptions.

WorkMagic
WorkMagic helps omnichannel brands measure the true impact of their marketing by combining incrementality testing, multi-touch attribution, and MMM into one unified platform. Its automated geo-based incrementality tests reveal what spend actually drives incremental sales across DTC, Amazon, retail, and wholesale. Instead of relying on guesswork or over-attribution from ad platforms, WorkMagic calibrates attribution models using real experimental results for maximum accuracy. Brands get a clearer view of performance, smarter budget allocation, and higher iROAS. Onboarding takes minutes, thanks to seamless integrations with Shopify, marketing channels, and marketplaces. With WorkMagic, teams finally understand what truly works—and what doesn’t—and can scale efficiently with confidence.

Stella
Stella is a marketing-measurement platform built to give marketers clear, scientifically sound insight into which ads, campaigns, and media channels actually drive incremental revenue. It includes three core tools; Incrementality Testing, Always-On Incrementality, and Media Mix Modeling (MMM). With Incrementality Testing, Stella runs geo-holdout studies (or inverse holdouts) to compare performance between test and control regions, isolating the causal impact of your ads rather than relying on attribution alone. It automatically handles complex statistical analyses (causal inference, confidence intervals, MAPE/R² checks), letting you see what would have happened without a campaign and therefore revealing the true “lift” generated by each ad. Its Media Mix Modeling tool uses a proprietary Bayesian MMM to decompose historical marketing spend and external factors (like seasonality, promotions, holidays, weather, etc.) to estimate each channel’s contribution to sales.
