Yes. With MixLift Local, data never leaves your machine — the full engine runs on your hardware via MCP with no data transmitted to any MixLift server. With MixLift Cloud, data is encrypted in transit and at rest and never used for training or shared with third parties. Pick the option that matches your compliance requirements.
MixLift auto-detects CSV exports from Meta Ads, Google Ads, and TikTok Ads. Generic CSVs work too — anything with date, spend, and revenue columns. On the Growth plan, you can skip CSV entirely and connect platform APIs directly.
The free tier supports up to 2 channels and 2 runs per month — enough to validate MixLift on your data. Growth at $299/month gives you 8 channels, unlimited runs, plus deliverables, connectors, and forecasting. Full comparison at /pricing.
A marketing analyst costs $120–180K/yr fully loaded. An MMM agency engagement runs $18–50K/yr, takes weeks to onboard, and gives you a PDF with no traceability. A fractional Head of Growth bills $8–15K/month. MixLift runs the same Bayesian methodology in 60 seconds for $299/month — and every number in the deliverable links to the model output so you can trace any claim yourself.
MixLift is built on PyMC-Marketing, an open-source Bayesian MMM library. It runs 4-chain MCMC sampling (No-U-Turn Sampler) to produce full posterior distributions for every channel's ROAS and saturation. Every estimate comes with a credible interval — not a point estimate. The same methodology underpins internal MMM work at Google, Meta, and Uber.
