Unbiased Customer Insights

We analyze unstructured free-text google reviews. These biases are context sensitive – as people a nudged via push notification, while still being at the store premises. These reviews are not biased also not incentived, e.g. via price competition or coupons.

Innovative Topic Model

We analyze and determin topics based on importance for customers of Aldi, Lidl, Rewe, Edeka, DM, Rossmann, Obi, Bauhaus and many more. Learn why 1) friendliness of staff, 2) price-value, 3) product selection, 4) cleanliness are most important to customers in Germany

Sentiments of Customers

What topics are usually seen critical by your customers, which are considered positive. Understand how “service at checkout” are rated differently between different brands. Learn in which areas Discounters beat supermarket chains such as Edeka and Rewe.
