-
DataLens is a data infrastructure platform that provides high-quality, human-validated datasets and annotation services for organizations building AI systems. We serve startups, enterprises, researchers, NGOs, and governments across industries like agriculture, finance, healthcare, and natural language processing.
-
We support annotation for multiple data types including images, text, audio, video, documents, and satellite data. Common tasks include object detection, segmentation, OCR, sentiment tagging, transcription, and entity recognition.
-
Yes. We offer end-to-end LLM fine-tuning services, including dataset preparation, prompt engineering, model training, and evaluation. Our goal is to optimize your language models for performance in specific domains or workflows.
-
We offer both. If you don't have existing data, we can help with custom data sourcing—from collecting satellite images to curating chat transcripts, surveys, or web-scraped content, depending on your use case and compliance needs.
-
All annotations go through a multi-layer quality assurance process, combining expert human review, sampling-based validation, and feedback loops. We also tailor quality controls based on the criticality of your use case (e.g., healthcare, finance).
