AI Data Services for
Any Language, Any Modality

We deliver annotated, collected and validated datasets — including low-resource languages — plus expert prompt engineering to accelerate safe, accurate generative and ML systems.

Your AI is Only
as Good as Its Data 

In the race to deploy generative AI and machine learning, the biggest bottleneck isn’t the model but the data it learns from. Inaccurate, biased, or culturally irrelevant data leads to poor performance, security risks, and costly delays, directly impacting your return on investment. 

In fact, data preparation alone consumes over 80% of the total time in a typical machine learning project. 

We take this cumbersome task off your team’s hands. Our integrated approach delivers the precise, reliable foundation your models need to perform accurately from day one. This frees you to focus on your core business: building and deploying transformative AI.
