About

Figure Eight began in 2007 in San Francisco as Dolores Labs, became CrowdFlower, and rebranded to Figure Eight in 2018. It pioneered crowdsourced data labeling, pairing a contributor crowd with ML-assisted annotation and video object tracking; the company said it delivered 325 million human judgments in 2018 alone. In March 2019 Appen agreed to acquire it for $175M upfront plus up to $125M in earn-out, closed that April, and by 2020 Appen reported all Figure Eight assets fully transitioned. The standalone product no longer exists. It earns a catalog entry as a landmark in annotation-platform history, and as a record of how the market consolidated around a few large vendors.
