Integrating human and machine intelligence to produce ground truth data for enterprise AI and ML projects, at any scale. 

“We’re swimming in training data, and I didn’t have to lift a finger.”

Data Annotation

We enrich your data to convert them into large-scale training datasets using a combination of machine learning and human judgement.

Model Validation

We help evaluate the accuracy of your model at every training stage via API data exchange, improving confidence with every iteration.

Exception Handling

After deployment, we help you to improve your model’s performance through human-assisted, real-time exception handling of edge cases.

We employ machine intelligence

Our platform handles millions of data items and thousands of workers simultaneously. It supports complex annotation requirements, and gets smarter throughout the course of your project.

We employ human intelligence

We draw from a nearly million-member global network of data specialists to curate the right team that meets your project’s scale, cost, domain expertise, and security requirements.

We take care of everything

We completely offload training data preparation from your team. You give us your data and requirements. We return high-quality datasets to you. It’s that simple, and that complete.
