Truffle debuts GEO platform in Germany as Cohaga expands AI visibility directory

Truffle, a new Generative Engine Optimization (GEO) tool hosted in Frankfurt, launched to help companies improve their visibility in AI‑generated answers from models such as ChatGPT, Claude, Gemini, Perplexity and Grok. The service tests brand mentions against persona‑specific prompts and delivers concrete recommendations for content optimisation, technical onsite measures and off‑site digital PR, positioning itself as a hands‑on alternative to existing monitoring‑only solutions.

Swiss firm Cohaga announced its Ranq directory, a searchable listing aimed at boosting AI‑visibility for businesses. Over 700,000 firms are already catalogued using publicly sourced data from Cohaga’s Leadhub platform, with entries verified both automatically and by a twelve‑person team in St. Gallen. Listings range from a free basic profile to paid tiers costing CHF 950–6,710 per year, offering features such as author boxes, model monitoring, knowledge contributions and a trust certificate. CEO Fabio Mätzler stressed that Ranq is a complementary lever, not a guarantee of AI recommendation.
