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
