How we
ensure quality
We use layered validation methods and detailed QA reports to ensure consistently accurate results.

Manual Review & Cross-Checking

Every dataset is reviewed by experts and, when needed, cross-validated by a second annotator.

Automated QA Techniques

We use Ground Truth, Honeypots, and Consensus to catch & fix frequent errors, cover edge cases, and ensure consistent quality.

Detailed QA Reports

You get full performance reports with a confusion matrix and key accuracy metrics (accuracy, precision, recall).
Secure & compliant
data labeling
We take data protection seriously, from legal safeguards to technical controls.

Privacy You
Can Rely On

All projects are governed by strict NDAs, and we follow GDPR and CCPA principles for data handling.

Secure Data
Storage

CVAT supports integration with your own cloud storage (AWS S3, Azure Blob, or Google Cloud), so your data never has to leave your environment.

Controlled
Access

Each labeling project has its own isolated workspace with role-based access available to you and your annotation team.

Frequently Asked Questions

What is the minimum amount of data you can label?
We don’t have a strict minimum in terms of data volume. Instead, we approach each project based on its complexity, annotation type, and quality requirements.

For example, labeling 100 images with one object per frame using bounding boxes might take just a few hours. But 100 images with 10+ objects per frame, labeled with polygons or instance masks, would be significantly more time-consuming and costly. Because of this variability, we scope projects individually and provide a tailored quote after reviewing your dataset and requirements.

That said, our minimum project budget starts at $5,000. This helps ensure we can allocate the right experts, maintain quality control, and deliver results that meet our standards. If you're unsure whether your project fits, feel free to reach out — we're happy to review your data and advise.
How fast can you deliver annotated data?
Our typical turnaround time for contracted projects is approximately 1 month, though we always strive to deliver results faster when possible.
Can you handle large-scale annotation projects?
Absolutely. We maintain a team of 300+ qualified annotators that we can scale up or down based on your volume requirements. We can also adjust our resources to match your data collection and training workflow and provide continuous annotation support through our subscription service model.
Who will be labeling my data?
Your data will be handled by our in-house team of annotation specialists. Each team member has undergone comprehensive training and has experience with dozens of annotation projects, ensuring consistent, high-quality results.
How do I start a data annotation project with you?
Getting started is simple. Fill out our contact form to discuss your project requirements and timeline.
What data labeling types do you support?
We provide comprehensive annotation services for images and video, including classification, object detection, segmentation, keypoint annotation, tracking, and action recognition. Our team adapts to your specific project requirements and data formats.
Can I order a pilot project?
Yes, we encourage pilot projects. During the project evaluation stage, we offer a free proof of concept that allows us to assess your data and requirements, define the budget, demonstrate our annotation quality, and introduce you to the CVAT platform where we perform the labeling work.
