scope of work

Marketing Effectiveness Audit (3–4 Weeks)
We diagnose:
Data gaps & quality issues
MMM feasibility
Past experiments & measurement gaps
Channel structure, granularity, spend patterns
Seasonality, promo, and pricing signals
Governance & workflow issues
Output: A decision-ready roadmap for building your MMM + Experimentation Engine
MMM Build Sprint (8–12 Weeks)
We construct a transparent, reproducible model:
Bayesian or regularized MMM tailored to your data
Saturation & diminishing returns curves
Seasonality, promo, macro adjustments
Media lag structures
Model diagnostics & uncertainty calibration
Cross-validation & out-of-sample testing
Output: A model your team can actually interpret — and defend.
Experimentation Program (Ongoing or Quarterly)
We design and run:
Geo experiments
Holdouts
Incrementality Tests
Pricing experiments
Creative/positioning tests
Optimal spend experiments
Output: Validated learnings that refine the MMM and guide budget moves.
Budget Reallocation & Scenario Planning
We help you answer:
“If we cut £X, where’s the least pain?”
“What if we add £Y to Meta/Search/TV?”
“What’s the true ROI of this channel?”
“What mix gets us the best incremental return?”
Output: Clear recommendations, confidence intervals, and next steps.
