End-to-End Data Preparation Services

Throughout the entire data preparation process, we collaborate closely with your team to provide you with highest-quality AI training data and expert guidance. From curating balanced and representative data, to tailoring annotator teams, processes and tools to your specific use case, we bring a human touch to each step of the way.

Challenges We Solve

Data Strategy

Each AI project has unique training data needs. With our decades-long experience in the data preparation space, we design end-to-end strategies customized to your project that improve the speed and scalability of annotation while delivering you exactly the high-quality training data that you need.

Data Sourcing

Sourcing the right data is the first step in assuring quality and reducing biases in AI. We support you in creating, curating and augmenting datasets that are relevant, representative and optimally aligned with your project. We augment datasets with synthetic data to improve coverage and balance and reduce bias in edge cases.

Data Annotation

With over 25,000 project managers, annotators and linguists across the globe, we build your annotation team to best fit your project. Supported by data labeling automation technology, humans in the loop and continuous quality feedback cycles, we provide nuanced annotation with speed and scalability.
