Our team is based in Berlin and we are excited to contribute to the European AI ecosystem.

Our Mission

AI is changing the way we operate. It automates routine tasks, allowing humans to reclaim headspace for activities that require their unique depth and creativity.

But careless AI deployment creates problems. When systems hallucinate or produce unwanted outputs, work quality degrades. Organizations are already dealing with the fallout.

We founded Blue Guardrails to help teams build AI responsibly. We help them tackle core technical challenges: preventing hallucinations, ensuring robustness, maintaining human oversight, and addressing fairness. Our approach is deeply embedded in the domain context of our customers.

The AI being built today will determine whether technology enhances or diminishes human capability. We exist to ensure it enhances—creating environments where AI makes work better, not just faster.

Let's Work Together

We are AI quality specialists who help engineering teams improve the reliability and accuracy of their AI applications through systematic hallucination detection and mitigation.
