Companies are increasingly licensing internal emails, Slack messages and documents to artificial intelligence developers, often without the knowledge of the employees whose communications generate the data, according to reports from Business Insider and the International Business Times [1][2]. AI firms including OpenAI, Anthropic and Meta are seeking real-world workplace records to train AI agents capable of performing tasks traditionally handled by employees [2][3].
The market has expanded as defunct and struggling companies look to monetize their internal archives, including employee emails, Slack messages and private workplace communications [4][5].
Employees whose communications make up the data may receive no share of the proceeds and may not be informed of the transactions, according to the reports [1][6]. The arrangements have raised questions about consent, privacy law and who profits from workplace records that workers often assume are confidential [1][6].
Brokers Report Growing Demand and Short Decision Windows
Brokers approach businesses with archives and offer to buy them, remove sensitive information and license the remaining data to AI developers [2][3].
The size of offers can depend on the volume of information, its exclusivity and the industry involved, according to the report [2][7]. AI companies are buying workplace data including Slack messages, emails, internal documents and tickets to train better models, with payments ranging from $100,000 to $2 million [7].
Spirit Airlines Archive Draws Lawmaker and Employee Concerns
Google said it was not seeking personal information and that such data would be excluded or de-identified by an independent third party, according to the reports [2].
Ifeoma Ajunwa, a law professor at Emory University, described the question of whether employee consent extends to subsequent sale of data as an "ethically gray area" [2]. The dispute highlights the unresolved question of whether consent to workplace data collection extends to its sale or licensing for AI training [2][6].
Security and Consent Questions Remain Unsettled
Nick Heiner, who works on AI training environments at Surge AI, told Business Insider that someone approached him offering a large company's codebase for millions of dollars; he concluded the group did not have the rights to sell it [2]. The account illustrates the legal uncertainty surrounding data provenance in the emerging market [2][6].
Meta faced internal backlash over plans to collect employees' keystrokes and mouse movements for AI training, according to reports [2]. Data intended to be anonymised became accessible more widely within Meta than intended, and the material reportedly included employees' private conversations and performance records [2].
Meta suspended the project following the incident, according to the reports [2]. The episode has been cited by critics as evidence that technical safeguards intended to protect employee data can fail during large-scale AI training efforts [2][6].
Market Growth Continues as Rules Remain Unclear
Alex Rosenblat, a sociologist and former Uber policy executive, said growing use of employee records to train AI could intensify calls for stronger privacy protections [2].
The dispute over the Spirit Airlines archive highlights the unresolved question of whether consent to workplace data collection extends to its sale or licensing for AI training [2][6]. As spending on AI data continues to rise, according to Gartner's forecast, the legal and ethical framework governing workplace communications remains unsettled [2].
