Apple loses Safari lead designer to Browser Company, the firm behind AI browsers Arc & Dia

“Apple’s lead Safari designer just joined @browsercompany. Alongside @charliedeets, that means we now have the lead designers from every Safari era that overlapped with Arc and Dia (2020 to 2025),” Miller wrote in an X post. Miller mentioned Triverio in his LinkedIn post.

Charlie Deets was another Safari designer. He quit in April 2024 to join The Browser Company.

In the last year, Apple has seen six senior executive departures, alongside dozens of other exits from teams such as AI, foundation models, and design.

The company behind Arc and Dia plans to channel its creative and engineering efforts towards strengthening its AI browser offerings. These have recently emerged as a key battleground in the tech industry, with ChatGPT-maker OpenAI rolling out Atlas and Perplexity introducing its Comet AI browser.

The Browser Company was acquired by the software development firm Atlassian in September last year for $610 million. The startup launched Arc in 2022, as a highly customisable browser featuring a built-in whiteboard and collaborative tab-sharing tools.

It then introduced Dia last June for Mac users, designed around AI interaction, which enabled users to converse with an assistant across multiple tabs.

Miller also revealed that all the designers that the Cupertino-based tech giant had between 2020 and 2025 have now moved to The Browser Company.

“Our intention is to build the densest, most extraordinary team of AI interface & product talent in the industry. And treat these exceptional individuals like the artists and craftspeople that they are. After seeing the way our our competitors have mimic'd DIa and other recent developments in AI, I’m more convinced than ever that the future of computing is in the browser layer. Now we want to double-down on that density of creative talent — with original ideas and stellar product instincts — who care about people and their lives more than models and benchmarks,” Miller wrote in his X post.

He also turned the announcement into a hiring call for users on X and LinkedIn, who may put to use ‘Claude Code and original creative instincts’ (to showcase their talent).
