Attribution is broken. You know it.

The old ways of measuring marketing leave massive blind spots. Spendmix fixes the three biggest problems.

Last-click lies

Last-click attribution gives all credit to the final touchpoint, hiding the channels that actually built demand.

Enterprise MMM costs $75K+

Traditional Marketing Mix Models require huge consulting engagements, months of waiting, and budgets only enterprise can afford.

Open-source needs a PhD

Open-source Bayesian MMM is powerful but demands deep statistical expertise, custom data pipelines, and weeks of configuration.

Three steps to clarity

From raw ad data to actionable budget recommendations in under a day.

Step 01

Connect

Link your Google Ads, Meta, TikTok, and other platforms with one-click OAuth. Data flows automatically.

Step 02

Model

Our Bayesian MMM engine builds your custom model automatically. Results in hours, not months.

Step 03

Optimize

Get plain-language insights and budget scenarios that tell you exactly where to shift spend for maximum ROI.

Everything you need

From data ingestion to boardroom-ready reports — all in one platform.

Stop pulling CSV exports

One-click OAuth connects your ad platforms. Spend, impressions, and conversions flow automatically — no more Monday morning data wrangling.

Models you can trust

Built on proven statistical methods with full uncertainty quantification. Know not just the answer, but how confident you should be.

No PhD required

Skip the posterior distributions. Get clear recommendations in plain English that your whole team — and your CFO — can act on.

Test before you spend

Drag sliders to simulate budget shifts. See projected ROI changes before committing a single dollar.
