PathFinder

The problem

Brand tracking programmes generate large volumes of survey data. The output is tracker dashboards or academic SEM tools. Tracker dashboards show every score moving and explain none of it. Academic SEM tools can establish cause and effect. However, they stay on an analyst's desktop, report results as path coefficients, and put no money value on them. Neither output answers the question every CMO asks, about which lever to pull and what it is worth.

The build

PathFinder answers that question with a tested model. The workflow is hypothesis-first: you state how you believe the brand works as a tiered structure (concrete attributes feeding brand perceptions, feeding equity dimensions, feeding the KPI you care about) and then test that structure against the data.

An AI agent speeds up the work of building the model. It reads the survey items, proposes tier assignments and causal paths, and hands them to the analyst for review. Nothing enters the model without a human approving it.

A model that passes validation gives access to the what-if laboratory. Move any driver by a few points and watch the effect propagate through the model to the KPI, expressed in percentage points and in money. Scenarios can be saved, compared, and exported. The model handles multiple brands and tracking waves, so competitor benchmarking and wave-over-wave movement are included as standard.

The workflow

The statistical engine is R running seminr for PLS-SEM, with bootstrap significance testing and fixed seeds so every result reproduces exactly. A Python service built on Flask orchestrates the workflow, Vue and D3 drive the interface, and the whole platform runs on Docker.

The outcome

Our brand equity engagements now end with a working simulator the client can run. The model is defensible in front of a sceptical finance director: the model tests each path, shows each validity check, and attaches a number to each recommendation. PathFinder is in active development and in use on live engagements. If you want to see it on your own tracking data, book a demo.
