TL;DR
Proton CEO Andy Yen cancelled employee re-interviews about AI use on Oct. 30, but said he would continue pushing for faster adoption. The company’s internal drive is reported by 404 Media, while Proton has publicly confirmed an AI-use review and says it wants to deliver features faster. No breach or exposure of user data has been reported; questions remain about code review, testing and how Proton measures AI-written code.
Proton CEO Andy Yen cancelled planned employee re-interviews about AI use on Oct. 30, while saying he would continue to push staff to adopt AI tools faster. The change follows public attention to internal messages, reported by 404 Media, urging quicker AI use at the Swiss privacy company, where employees build products relied on by users for encrypted communications and storage.
Proton had told staff by email on Oct. 26 that it would re-interview employees about how they use AI between Nov. 4 and 11. The company published the email on Reddit, saying it was “not doing layoffs and using AI as an excuse” and that it needed to “deliver features faster to users.” At an all-hands meeting four days later, Yen cancelled the interviews and acknowledged “a communication failure on my part,” according to audio reviewed by 404 Media. He added: “Going forward, I’m still going to push.”
The internal exchanges were reported by 404 Media on Oct. 29, based on interviews with eight current and one former employee, along with Slack messages, meeting audio and internal documents. The outlet reported that Yen told staff to “stop lovingly handcrafting all our code and use AI more” in a security Slack channel. A Proton spokesperson “did not dispute” the reporting, 404 Media said. The material has not been independently confirmed by another outlet.
404 Media also reported that Proton CTO Bart Butler said in an internal meeting that AI wrote 90% of Proton’s code in October. That figure is an internal claim, not an independently measured statistic; the reporting does not define what counts as “written by AI.” No security breach or user-data exposure was reported. The issue raised in the account is how AI-assisted code is reviewed and tested, not evidence that Proton’s protections have failed.

How Faster Coding Affects Trust
The dispute matters because Proton’s business depends on user trust, and software security depends not only on product promises but also on how code is written, checked and deployed. AI tools may help engineers produce features faster, but speed does not by itself establish that code has received adequate security review. The available reporting does not show that Proton skipped testing or that a vulnerability resulted from AI-generated code.
For users, it is useful to separate two questions: whether a particular service protects data as described, and whether the company’s internal development practices provide enough scrutiny. Proton’s statements about encryption and privacy products describe its intended protections; the employee concerns reported by 404 Media point to questions about process. Neither the internal messages nor the company’s public AI claims, on their own, establish that user data is at risk.
The development also puts Proton’s approach to AI in view. Yen has publicly described AI as a technology he would prefer not to see, while arguing that privacy-focused companies must build alternatives. That position can coexist with a push for staff to use AI internally, but it leaves customers and employees looking for clear explanations of safeguards, review standards and accountability.

Proton’s AI Products and Position
Proton, a Swiss company founded after the 2013 Snowden disclosures, began with encrypted email and has expanded to products including Drive, VPN, a password manager and Calendar. In a WIRED interview published Aug. 18, Yen said the company had over 100 million users. That is his stated figure, not an independently audited count in the material provided.
Proton launched its Lumo chatbot on July 23, 2025. It released Lumo 2.0 on June 30, 2026, describing it as offering “zero-access encryption, no logs, no data sharing, and no training on your conversations.” Those are Proton’s product claims. On Sept. 17, the company added Apertus, an open model developed by Swiss universities, to Lumo, with an opt-in feedback channel. On Oct. 22, Proton added a canvas for working with documents, code and web pages.
Proton Scribe, a writing assistant for Proton Mail, can run on Proton’s servers or on a user’s device. In the WIRED interview, Yen said privacy companies needed to develop privacy-focused AI rather than leave the field to larger technology firms. He also said, “I would probably prefer a world where AI didn’t exist, but it’s here.” Separately, 404 Media reported that Yen told employees, “The train is coming, get onboard or get crushed.” The latter wording comes from the outlet’s account of internal communications, not a public company statement.
““We’re not doing layoffs and using AI as an excuse” and need to “deliver features faster to users.””

Security Checks and AI Metrics
Several details remain unverified publicly. The 90% code figure comes from an internal meeting, and the reporting does not specify how Proton calculated it or distinguish AI-generated code from AI-assisted work. It is also unclear what code review, testing and approval requirements apply to different kinds of AI-written code, or whether those processes changed alongside the adoption push.
The internal account is based on material reviewed by 404 Media and its sources; no other outlet has independently obtained the messages, according to the supplied report. Proton cancelled the re-interviews, but the company’s broader internal AI policy and any replacement process have not been fully detailed in the material. Proton did not respond to 404 Media’s request for comment on the Oct. 30 report, the outlet said.
No breach has been reported, and the reporting does not establish that user information was exposed or that AI-generated code caused a security flaw. It also remains unclear whether Proton will publish more detail about safeguards or how it evaluates AI use across engineering teams.
What Proton Users Can Check
Proton’s immediate stated plan to re-interview staff from Nov. 4 to 11 was cancelled on Oct. 30. The company says it will still push for greater AI use, but the next public milestone is unclear. Further information from Proton about engineering review standards, internal measurement of AI use or revised staff guidance would clarify how the policy operates.
Users can review the settings and product information available now. For Lumo, that includes chat history, web search and feedback settings; for Proton Mail, users can check whether and how they use Scribe. Those choices address product-level features and data handling, but they do not answer internal questions about software testing. Users seeking assurance on that point will need public detail from Proton about its development and security processes.
Key Questions
Did Proton cancel its AI push?
No. Yen cancelled the planned employee re-interviews on Oct. 30, but said he would continue pushing for faster AI adoption.
Did Proton say it was laying off staff because of AI?
No. In the Oct. 26 email it published on Reddit, Proton said it was “not doing layoffs and using AI as an excuse.”
Has Proton reported a breach or exposed user data?
No breach or user-data exposure was reported in the supplied material. The reporting concerns how code is produced, reviewed and tested; it does not establish that a security failure occurred.
Is the claim that AI wrote 90% of Proton’s code verified?
The figure was attributed to CTO Bart Butler at an internal meeting, according to 404 Media. It has not been independently measured in the material, and the meaning of “written by AI” was not defined.
What can users do while details remain unclear?
Users can review Lumo’s chat history, web search and feedback settings, and decide whether to use Proton Mail’s Scribe writing assistant. These settings do not establish how Proton reviews code internally.
