Why choose us

Our advantages

Data security

EU-based and GDPR-compliant

We are headquartered in the European Union and we are fully compliant with GDPR regulations. We reduce the transfer of sensitive data at a maximum. Datasets are collected and annotated with special attention to biometric and personal data.


Transparent and flexible pricing

We use a standard hourly rate and we calculate a per-file or per-annotation price based on the amount of time they take to complete on average. We have no additional or hidden fees for quality control, project management or tool usage.

Project management

Dedicated teams and manager

We assist you in scoping your project and choosing the appropriate tool, and we complete the tasks in several iterations based on your feedback. One team works on all batches from the same client so as to develop expertise and consistency.
