Another senior Apple employee has defected to another company, as the Cupertino firm has lost one of its lead designer from its Safari browser team, Marco Triverio, to The Browser Company. The exit is just the latest high-profile Apple employee that has left the company.
Triverio has joined The Browser Company, the developer of the Arc and Dia browsers. The Browser Company chief executive Josh Miller confirmed the move in a post on LinkedIn, marking the latest in a series of hires from Apple’s Safari design leadership.
Big news: Apple’s lead Safari designer, Marco Triverio, just joined The Browser Company!
Alongside Charlie Deets, we now have the lead designers from every Safari era that overlapped with Arc and Dia browsers (2020 to 2025).
We’re not messing around this year! Come work with us if you care more about people and making their daily lives better than models and benchmarks.
The Browser Company says that by building Arc and now Dia, they are offering a browser “that’s aren’t just faster, but also more personal, focused, creative… and maybe even more fun.”
In October 2025, the Browser Company released Dia AI-powered browser for Macs powered by an M1 or higher processor.
Dia browsing experience is centered around tab-based AI chat functionality. The browser offers a “Skills” feature, which are a mix of user-created and built-in shortcuts for everyday tasks like planning, learning, writing, and coding. Skills currently available include a one-click fact checker, summarization, browsing history analysis, productivity planning, and more.
The browser’s AI can understand preferences over time, and users can mention tabs in any chat query and add attachments to conversations. Students can use the browser’s dedicated tools to turn readings, notes, and lectures into custom study guides, flash cards, and other study tools.
