Hans Kuepper

Hans Kuepper is an independent developer focused on building privacy-first tools for the AI era. He is the creator and maintainer of PromptQuorum, a multi-model AI dispatch and consensus platform.

PromptQuorum emerged from a specific frustration: when you need a reliable answer from AI, querying one model is not enough. Every AI model hallucinates differently. The truth is in the overlap.

Before building PromptQuorum, Hans spent years working with enterprise AI workflows and observed the same pattern repeatedly: teams trusting single-model outputs for high-stakes decisions without any verification layer. PromptQuorum is the tool he wanted to exist.

His approach to product development is characterized by three principles:

• •Privacy First: Your data never touches PromptQuorum servers. API keys connect directly from your browser to your chosen providers.
• •Transparency: PromptQuorum is free, open, and requires no registration. You own the experience.
• •Multi-Model Focus: No vendor lock-in. Dispatch to 25+ models, compare results, find the best for your task.
