A unified data layer across European marketplaces
Connectors for Allegro, Amazon, Kaufland, Castorama, and others — sales, ads, and unit economics in one place.

- Platforms
- Allegro, Amazon, Kaufland, Castorama, and more
The problem
Selling on five European platforms meant five back-offices, five report formats, five currencies of truth. Comparing performance across platforms — or just answering “what did we actually earn on this SKU?” — took days of manual exports.
What we built
- Connectors for Allegro, Amazon, Kaufland, Castorama, and other platforms — orders, ads, fees, and stock.
- A unified warehouse where every platform’s data lands in one consistent model.
- Unit economics per SKU per platform: fees, ads, logistics, returns — all factored in.
- Ads orchestration: campaign performance across platforms in one view.
- Operational dashboards for daily work and management reporting.
How it works day to day
One place answers the cross-platform questions: which platform actually makes money on which SKU, where ads pay off and where they burn budget, and what needs restocking where.
Outcome
Cross-platform decisions — pricing, ads budgets, assortment — are made on one consistent set of numbers instead of five exports.
The data layer scales: adding the next marketplace is a connector, not a new back-office.
