Popular Questions

What makes your data "customized"?

Your dataset is created specifically for your requirements, no generic data. Participants follow your exact specifications.

How much does it cost?

The cost is based on the number of unique participants you require and how much work they need to do.

We work with clients on a rolling monthly subscription, so you can cancel or pause at any point. Payments can be made by credit card or invoice, depending on the size of the project.

Do you have examples?

We can create samples if you contact us. We also have our dataset marketplace.

What does my Project Manager do?

Creates procedures, writes instructions, sources expert annotators, ensures quality, and serves as your single point of contact.

What is “training data” in machine learning?

Data that is used to train AI models to make predictions. Can include images, text, audio, or structured data. Quality training data determines how well your AI performs.

What is data labeling?

Adding tags to raw data (images, text, audio) so AI models learn to recognize patterns. Quality labeling determines model accuracy.

What is ethical data collection?

We secure informed consent from all participants who understand exactly how their data will be used. We strictly follow GDPR compliance and documented consent for every project.
