# auffindbar.ai

> GEO and GEA agency for AI visibility in the German-speaking market. We help businesses, nonprofit organizations, and institutions become visible and recommended in the answers of AI systems such as ChatGPT, Google AI Overviews, Gemini, Microsoft Copilot, Claude and Perplexity.

auffindbar.ai GbR, Selneckerstraße 3, 04277 Leipzig, Germany. Locations: Leipzig · Ingolstadt. Founded in 2026 by Dennis Doerfl (CEO) and Thomas Müller (CMO). We work exclusively on AI visibility, both organic (Generative Engine Optimization, GEO) and paid (Generative Engine Advertising, GEA, in the DACH market), and exclusively for the German-speaking market: Germany, Austria, and Switzerland.

Generative Engine Optimization, also called Answer Engine Optimization (AEO), Large Language Model Optimization (LLMO), AI SEO, or AI visibility, is the alignment of a business’s website, content, and digital reputation so that AI systems understand the business and can recommend it in their answers or use it as a source.

Mention Rate: share of AI answers in which a brand is named. Citation Rate: share of AI answers in which the website is visibly linked as a source. Share of Voice: a brand’s share of all provider mentions across the measured AI answers. Visibility Score: a value between 0 and 100, calculated as 0.7 × Conquer (non-branded) + 0.3 × Defend (branded), with both calculated as 0.6 × Mention Rate + 0.4 × Citation Rate.
