Ralf Dümmel: How Retail Hypes Survive on Shelves
Investor Ralf Dümmel appears on the podcast "Supermarkt Macher" to discuss product launches, shelf dynamics and the tension between gut feeling and data in retail. Dümmel—an investor on the TV show Die Höhle der Löwen since 2016 and head of his DS‑Gruppe—shares that one investment cost him €50,000 but ultimately became a €1 million loss, and that his group has brought over 4,000 products to shelves across roughly 215 start‑up deals. Recorded at the Palmengarten before the "Supermarkt Stars" awards, the episode covers practical merchandising rules (including a 3‑second rule and three customer groups at the shelf), the rising role of private labels, and why listings often stall between start‑ups, store managers and retail headquarters. The episode is available on major podcast platforms.
Company/personal interview with practical retail merchandising insights; useful for retail and brand practitioners but not industry‑shifting for AdTech/MarTech.

Monopolkommission warns of competition pressure after EDEKA-tegut takeover
The Monopolkommission, Germany's monopoly commission, has warned that competition in the German grocery retail market is under pressure following EDEKA's acquisition of 178 tegut stores. The Bundeskartellamt had approved the deal with conditions, prohibiting EDEKA from acquiring 24 additional tegut markets for four years to mitigate regional competition concerns. The commission notes that the four largest grocery groups (EDEKA, REWE, Schwarz Group, and ALDI) already account for more than 90% of market revenues. The Monopolkommission criticizes the ongoing market concentration, which it says strengthens the market power of large retailers over suppliers and may lead to price alignment. It calls for more detailed data and closer monitoring of the market to prevent potential abuses.
