Proton CEO Andy Yen projects a calm persona and rails against Big Tech and critiques AI. Internally, he is pushing engineers to build Proton with AI, even when they have security concerns.

Andy Yen, the CEO of Proton, had a message for an employee in the company’s security Slack channel who urged the company to at least take a few days to pentest newly written code before pushing it live. “That’s bullshit and loser thinking. Of course it’s possible to be fast and secure,” Yen wrote in the channel at the end of August. “Stop thinking always of how to be slower, and focus more on how to be faster.”

In a follow-up message, Yen reiterated his point: “only losers think like that.” His ultimate message for the team was to “stop lovingly handcrafting all our code and use AI more.”
