Company Overview

Hcyon is a healthcare data labeling company based in Amsterdam, providing expert annotation services for medical AI development. What we do: - Medical imaging annotation (X-rays, MRIs, CT scans, pathology slides) - Clinical document labeling (patient records, clinical notes, medical reports) - LLM fine-tuning support (RLHF, preference data, instruction tuning) What makes us different: Our annotators are practicing doctors, dentists, and medical specialists from the Netherlands, Germany, and across Europe, not crowdworkers guessing at medical terminology. Every team member is individually vetted for domain expertise and quality. Our mission: Twenty-five centuries ago, a Greek physician wrote an oath that still guides medicine today: First, do no harm. Medical AI will touch billions of lives. It will read scans, suggest diagnoses, flag emergencies, miss others. The harm it could do is immense. So is the good. The difference is in the foundation: the data, the labels, the humans who taught it what to see. We believe that foundation should be built by people who understand what's at stake. Not the fastest bidder. Not the cheapest option. Doctors. Specialists. Professionals who took that same oath. Fast and cheap, or careful and right. In healthcare, that choice has consequences. We're here to get it right.
