How it works

Upload your dataset to our secure cloud and create labeling tasks. When you're ready, launch your tasks to our network of medical experts.

See results within days, not months.

Try it out
We've worked with researchers and practitioners at the forefront of AI.

Their platform is able to provide labels at a scale that was 10x, maybe 20x, anything that we had done by ourselves.

Tremendous scale, tremendous throughput, and high quality labels.

Why we're different

clipboard with multiple opinions collected

Collective intelligence outperforms the competition

By aggregating many opinions, we achieve a level of accuracy proven to outperform any individual board-certified doctor.

Performance-based compensation aligns incentives

We only reward the top performers, so our medical experts give 100% effort on every case they see — ensuring quality at every step, and allowing us to pass cost savings onto you.

Our customers and partners are saying

Centaur's mobile-first labeling tools enable us to quickly and conveniently gather results from our residents. We've accelerated our research by building and refining our ML models on COVID-19 pathologies in near real time. Centaur Labs has been a crucial partner throughout.

Centaur Labs is an amazing resource. So amazing that I almost don't want others to know about it because of how easy they make it to build up high quality training data. Their user base combined with their application allowed us to easily and efficiently scale up our training data in a very controlled way that ensured it was high quality based on metrics we cared about in-house. I would without hesitation recommend their service, so long as you are not doing what we are doing!

Any data scientist will love working with Centaur Labs. They provided us with rich information on labeler disagreement that is both critical to publishing results of our work and unlike any labeling vendor out there. Our project also had unique requirements for the population of labelers, and Centaur was able to recruit over 650 labelers that met those requirements.

We knew we couldn’t rely on individual neuroradiologists—or traditional, non-medical outsourced labeling services—to segment different kinds of hemorrhages in thousands of brain CT scans. Centaur tackled this problem quickly and accurately, enabling us to focus our time on building cutting-edge AI.

I was surprised when Centaur Labs projected a turnaround time within a week of our meeting. Not only did they meet that deadline, the Centaur network also determined that our dataset included over a hundred irrelevant clips.

Their quality control process made it easy to review controversial cases—which would have taken weeks without their support
