Labelbox

Labelbox is an AI data platform that helps teams create and manage the training data needed to build and improve machine learning models. The platform provides tools for data labeling, annotation, curation, and quality management across image, video, text, audio, and geospatial data types.

Labelbox's platform combines human labeling workflows with AI-assisted annotation to accelerate the data preparation process. Features like model-assisted labeling use existing models to pre-annotate data, which human reviewers then verify and correct — dramatically reducing the time and cost of creating high-quality training datasets.

The company serves AI teams at enterprises and AI companies across industries including autonomous vehicles, healthcare, defense, and agriculture. Labelbox has raised over $190 million in venture funding and has evolved from a labeling tool into a comprehensive AI data platform that supports the entire data lifecycle from collection through model evaluation and iteration.
