From the article:

AllDone’s managers increasingly turned to the company’s digital assembly line in the Philippines, where contractors performed computational work that stood in for or supported software algorithms.

AllDone had hired its first work-from-home Filipino contractor a few months after the company’s launch. Within a year, the team had grown to 125, and during my research it expanded to 200. Most contractors were college educated and between the ages of 20 and 40; about 70 percent were women. Executives often called these workers AllDone’s “human machine.”
