gerlinger.ai is the AI and software unit of JANGER GmbH, based in Backnang near Stuttgart, Germany. We build web apps and AI solutions for small and medium businesses across the German-speaking market, with a focus on e-commerce and retail, construction and skilled trades, mechanical engineering and industry, and real estate.
At the centre are tools that run inside the business every day: lead scrapers, quote and invoice automation, dashboards and configurators, internal knowledge systems where staff find answers from manuals and customer files in seconds, plus chatbots and intelligent websites.
What makes this possible is agentic coding, software development with AI agents. It brings tools within reach that used to be unaffordable for a small company. What starts as a single tool grows together: instead of many isolated solutions and subscriptions, you end up with one company app.
On top of that comes consulting on Claude Code and agentic ways of working: teams learn to use AI themselves instead of needing an agency for every adjustment. Everything is built with high-quality UX and modern design, because only a tool that people enjoy using actually saves time.
Jannis Gerlinger shows how this looks in practice on the YouTube channel @gerlinger-ai and on the gerlinger.ai blog. Self-employed since 2007, more than 200 clients supported.
