Dargel Solutions is a Kleingewerbe under § 19 UStG, the German small-business VAT rule, based in Frankfurt am Main. There are no departments: the same person writes the code, builds the digital products, runs the automation, and answers the mail.
The work uses current AI models from Anthropic and OpenAI, including Claude and ChatGPT. For material outputs, several models run in separate steps and check one another. Before publication or a binding decision, a human reviews the result and releases it.
The mandatory provider details under § 5 DDG are in the imprint.
Dargel Solutions can develop and operate custom software solutions for other businesses: from lean internal tools to production-ready web applications.
The right starting point is a short, concrete description of the problem, the existing systems, and the desired outcome.
