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."

"I get pitched on annotation tools all the time and Centaur is simply the best ... they offer you the accuracy and sophistication of medical experts at the price and speed of Mechanical Turk.

"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."

"Segmenting graft-versus-host skin disease is a complex and time consuming task. Centaur collected over 10 vetted opinions per image from their network, and combining those segmentations together produced amazingly high-quality annotations."

"Centaur Labs leverages an ensemble of physicians to annotate medical data for machine learning, which makes their approach highly accurate and scalable."

"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.”
