Three blind spots your existing stack leaves you with
01 — What the demand-side market actually looks like Stackline shows you Amazon. Nielsen shows you offline sales. Neither shows you the demand structure — the segments consumers organise themselves into via search behaviour, before they reach your store.
02 — What customers say about the SKUs you stock Reviews on your site are biased upward. The reviews on Amazon and YouTube — where the actual purchase research happens — are absent from your decisions.
03 — Why you're losing organic share on category pages You used to outrank brands and Amazon for "best stroller UK" and similar. Now you don't. The reasons are technical AND content-related — and our data shows you exactly which.
What Theia delivers for retailers
A. Cluster maps for every category you sell A live market structure: what consumers actually treat as substitutable. The 11-segment headphone market or the 7-cluster gift market — refreshed weekly.
B. PLP intelligence for every retailer page you compete with Across 20+ retailers per market we already track: Argos, John Lewis, Currys, Smyths, MediaMarkt, Boulanger, Fnac, Aubert, Babylist, Buy Buy Baby, Babymarkt, Baby Walz, Prenatal — page-level visibility, content quality, ranking trajectory.
C. Per-SKU consumer voice For every ASIN/SKU in your range, what customers say across Amazon, YouTube, Reddit, parenting forums — sentiment by property, language by language.

Step 3 — Weekly: Receive the PLP movement report
↓
Output: Where your category pages are moving in SERPs. Where competitors got ahead.
Step 4 — Monthly: Content production for the underperforming PLPs
↓

The anchor proof — Bose Germany
The 11-segment headphone map. A retailer ranging from data, not from supplier pitches, would have:
- 5 segments where the field is concentrated → "must stock"
- 3 segments dominated by brands you'd not currently prioritise → "expand"
- 3 segments where existing range overlaps heavily → "tail-drop candidates"
A ranging decision that a 2-hour supplier meeting can't surface.
