Media Appearances
A high-profile, investigative 2019 documentary titled ''Ghost Workers'' was about the labor practices and workers of Biewald's company Figure Eight Inc., with Biewald as a central character. The creators focused on a clip of the company's founder, Lukas Biewald, speaking during an in person technology panel, describing his attitude toward online, remote contract workers, emphasizing the ability of the internet to facilitate worker disposability and the ability to pay workers small amounts of money.
Biewald's attitudes toward worker pay had raised eyebrows before, with ''

'' also quoting Biewald saying, "Before the Internet, it would be really difficult to find someone, sit them down for ten minutes and get them to work for you, and then fire them after those ten minutes. But with technology, you can actually find them, pay them the tiny amount of money, and then get rid of them when you don’t need them anymore."
When questioned by The Nation, Biewald framed his approach a bit differently stating online "crowdwork"-dependent businesses of his type were, "bringing opportunities to people who never would have had them before, and we operate in a truly egalitarian fashion".
The documentarians in ''Ghost Workers'' interviewed and followed the lives of two contract workers for Figure Eight, including a top ranked Figure Eight contract worker in Maine who used Figure Eight as a primary income source. This top ranked worker was living in

, spent entire days on the platform to increase her rank on the site, and described the pay as unfair. She described on a "good day" she made about $5/hour and on a "bad day", around 10 cents an hour working for Figure Eight Inc. The documentarians also timed another worker while working on the platform, confirming he was making pennies on the dollar per hour working continuously categorizing consumer products. The documentarians then confronted Biewald and his PR representative in person about labor practices after having interviewed him about other topics. Lukas claimed to have little to no knowledge about average worker pay on his own platform, concluding by claiming, "I don't really know how much people really make". He also physically walked out of the interview after being asked about the legality of paying under minimum wage, while the PR representative tried to replace his absence during the interview. As the PR representative was confronted with worker accounts they discovered, the PR rep announced he too was leaving. Shortly after this interview, Biewald sold the company.
