Scale AI is an American data annotation company in San Francisco, California. It provides labeled data used to train AI applications.

Scale was founded in 2016 by Alexandr Wang and Lucy Guo who had previously worked at Quora.[1]

Initial investors of Scale included Dragoneer Investment Group, Tiger Global Management and Index Ventures.[2][3][4]

In 2018, co-founder Guo left Scale "due to differences in product vision and road map".[2]

In August 2019, after Peter Thiel’s Founders Fund made a $100 million investment in Scale, its valuation exceeded $1 billion and it acquired Unicorn status.[2][3]

By July 2021, Scale had reached a valuation of $7 billion, after a financing led by Greenoaks, Dragoneer Investment Group and Tiger Global Management.[5] There was an increased demand for data labelling from clients in different industries.[4]

In January 2023, Scale laid off 20% of its workforce.[6]

In March 2024, Scale reached a valuation of almost $13 billion after Accel lead another round of funding.[7] In May 2024, Scale raised an additional $1 billion with new investors including Amazon and Meta Platforms. Its valuation reached $14 billion.[8]

In December 2024, Scale was sued by a former employee with allegations that it was committing wage theft and misclassifying workers.[9] The following month, a second employee filed suit against the company citing similar claims.[10]

In January 2025, several contractors sued Scale alleging psychological harm from being exposed to toxic material, such as content related to violence and child abuse.[11]

In 2017, Scale established Remotasks, an in-house outsourcing agency with facilities in Southeast Asia and Africa to train data labelers. Remotasks has been established as a separate brand for client confidentiality according to Scale. The operation was accused of low pay, failing to meet "minimum standards of fair work" and that the "obfuscation" of its association with Scale creates confusion that "can contribute to workers’ vulnerability to exploitation."[2][12]

In March 2024, it was reported that Remotasks had terminated its services in whole countries without explanation. Workers in Kenya, Nigeria, and Pakistan found themselves cut off from accessing its services. Remotasks has also halted new sign-ups in Thailand, Vietnam, and Poland. A Remotasks representative claimed an administrative error was to blame for the lack of notice provided to contractors in Kenya.[13]
