Figure Eight
Figure Eight's Overview
Figure Eight, originally founded as Dolores Labs in 2007 and later known as CrowdFlower, was a pioneering human-in-the-loop machine learning and AI training data platform. It specialized in providing high-quality annotated data for training machine learning models across various applications like computer vision, natural language processing, and search relevance. The platform combined human intelligence from a global crowd with machine learning tools to create, label, and enrich datasets at scale. In March 2019, Figure Eight was acquired by Appen, a global leader in AI training data, further enhancing Appen's capabilities in the rapidly growing AI market. Figure Eight's technology and expertise continue to contribute to AI development under the Appen umbrella.
