Figure Eight Inc.

Figure Eight (formerly known as Dolores Labs, CrowdFlower) was a human-in-the-loop machine learning and artificial intelligence company based in San Francisco.

Figure Eight technology uses human intelligence to do simple tasks such as transcribing text or annotating images to train machine learning algorithms.

[5] After experimenting with pictures and questions related to them on Amazon's Mechanical Turk, a crowdsourcing internet marketplace, they encouraged others to participate in their experimentation through the site Facestat.

They collected 20 million assessments of people's faces within three months and began to add queries for companies needing data such as event listing site Zvents and O'Reilly Media.

[6] Dolores Labs, initially in a loft space in the Mission District briefly moved to an office on Valencia Street which it outgrew in nine months.

[14] The company established a scientific advisory board in 2016, which made up of entrepreneur Barney Pell, founder and CEO of Kaggle Anthony Goldbloom, and staff research engineer at Google, Pete Warden.

[27] In May 2017, CrowdFlower released an enhancement for its Computer Vision software, announced during the Train AI conference, designed to simplify and speed up the process of annotating images.
