What KOOS does
KOOS Edelmetalle GmbH is a German family-owned precious-metals company headquartered in Renningen, Baden-Württemberg, between Stuttgart and Pforzheim, operating since 1980 under second-generation ownership led by Kevin Koos. The business is structured around five divisions — jewellery, recycling, investment, semi-finished products, and dental — and serves B2B customers including jewellers, goldsmiths, dental laboratories, and precious-metal wholesalers and retailers. No external funding, M&A activity, or institutional investment has been disclosed, consistent with its private Mittelstand status.
The company's core operations revolve around physical precious metals — buying, refining, and selling gold, silver, platinum, and palladium across multiple form factors. A claimed operational differentiator is a two-hour immediate refining service without melting, positioned as unique within the German market. Distribution is increasingly digital: a customer portal provides real-time precious-metal pricing, online shops transact across the product range, and a precious-metal account allows counterparties to hold and settle in metal positions. The German retailer trade recognized KOOS with over 350 specialist retailers voting it best supplier for 2025, and the company maintains a charitable partnership with Deutsche Kinderkrebsstiftung.
Revenue mechanics are not disclosed, and the company operates with a 1–10 employee footprint, which is structurally consistent with the high-revenue-per-head profile typical of precious-metals dealers handling high unit-value commodities. The business model relies on spread capture, refining fees, alloy sales to dental laboratories, and recurring portal-driven trade, with no disclosed AI, patent, or proprietary technology stack beyond the digital portal and metallurgical refining capability.
