Frequently Asked Questions
Where is Perinola based?
Perinola LLC is incorporated in the United States. Our operations are powered by a multidisciplinary expert team in Latin America, with more than 20 years of proven business experience in the region.
How do you ensure quality?
Every dataset goes through a multi-step QA process combining human validation and automated checks. Each project is assigned an account manager to oversee consistency, communication, and client satisfaction.
Do you offer more than just labeling?
Yes. While labeling is our core service, we can also train baseline AI models, provide dataset structuring, and advise on scaling annotation pipelines.
What types of annotation do you provide?
We support bounding boxes, polygons, semantic segmentation, keypoints, OCR, video frame annotation, and dataset structuring with balanced Train/Valid/Test splits.
Will I have direct support during my project?
Absolutely. Each client is assigned a dedicated account manager who ensures smooth communication, fast turnaround on questions, and end-to-end project visibility.
What formats can you deliver datasets in?
We deliver in all industry-standard formats, including YOLO, COCO JSON, Pascal VOC, and TFRecord. Custom export formats can also be supported upon request.
Can I start with a pilot project?
Yes, we encourage pilot projects. We can provide a proof of concept to evaluate your data and requirements, demonstrate our annotation quality, and ensure alignment before scaling. This allows you to see our workflow, meet your dedicated account manager, and gain confidence in the value we deliver.
Can you handle projects of different sizes?
Yes. We work with startups, research teams, and enterprise clients alike, adapting to your scale and timeline.
Do you work with both images and videos?
Yes. We annotate static images, video frames, or continuous video sequences using interpolation to optimize efficiency.
Do you also provide model training?
While our core focus is high-quality data labeling, we can optionally train baseline AI models on your dataset to validate annotation quality and provide a starting point for your machine learning pipeline.
