Independent by design
MMM Audit is a focused offering for teams who need a credible second opinion on their marketing mix model, without a sales agenda for a particular stack or vendor.
About
We combine deep technical expertise in Bayesian and causal inference with in-house marketing effectiveness leadership. Two of our specialists are IPA Effectiveness Awards technical judges. The work is delivered with Tyedal, alongside partners at Inference Works and practitioners working day-to-day in in-house measurement.
We never audit a model any of us built or contributed to. If the right answer is a rebuild, we say so, and we will not quietly pitch ourselves as the only option.
