Atlassian, the Australian company behind workplace tools like Trello, Confluence, and Jira, is acquiring The Browser Company of New York for $610 million, following an earlier investment from Atlassian’s venture capital arm. On its Keeping Tabs blog, The Browser Company of New York writes:

Today, The Browser Company of New York is entering into an agreement to be acquired by Atlassian in an all-cash transaction. We will operate independently, with Dia as our focus. Our objective is to bring Dia to the masses.

Overall, I believe this is a positive move for users of the Arc browser. The acquisition gets The Browser Company out of the venture capital rat race and moves it under the oversight of Atlassian, best known to TidBITS readers for its 2017 acquisition of Trello, the task management tool we used extensively during the Take Control days (see “Trello Offers Compelling Collaboration Tool,” 9 July 2012). Atlassian also develops Jira, a project management platform, and Confluence, a collaborative documentation tool, both primarily targeted at developers.

The Browser Company claims it will remain independent and continue to focus on Dia. The company has also promised to share long-term plans for both Arc and Arc Search, though I have doubts about its roadmap after it shifted away from Arc (see “Dia Browser Debuts with Contextual AI Chat, But Arc Users Feel Left Behind,” 20 June 2025, and “Dia AI Browser Introduces $20 Monthly Pro Plan with Unlimited Chat,” 8 August 2025). I’d be happy if those plans turn out to be more than acquisition announcement assurances aimed at assuaging anxiety about Arc. (Sorry, couldn’t resist.)

In Atlassian’s press release, CEO Mike Cannon-Brookes accurately points out the challenge encountered by modern Web browsers.

Today’s browsers weren’t built for work. They were built for browsing – reading the news, watching videos, looking up recipes. And sure, you may do some of those things in your browser during the workday, but most of those tabs represent a task that needs to get done. A meeting to schedule. A design to review. A work item to update in Jira. A memo to write. Before you know it, it’s hard to see through the forest of tabs.

Cannon-Brookes elaborates on these points in an accompanying video.

The Browser Company had effectively tackled many of these workflow issues in Arc before pivoting to Dia. I occasionally use Dia instead of a ChatGPT pinned tab in Arc, but as someone who does real work on the Web, Arc’s dashboard for single-click navigation among the many websites I use daily is far more necessary than Dia’s chatbot. Hopefully, Atlassian will recognize that knowledge workers need both if they’re to use Web tools efficiently.

We’ve used Atlassian products (JIRA, Confluence, and Trello) for many years, but can only afford to because we’re a non-profit. The platforms are solid, but not user-friendly at all (with the exception of Trello). As much as I hate to say it JIRA and Confluence are overpriced corporate bloatware that hasn’t innovated for a long time.

How is the Browser Company worth this much? What technology do they bring to Atlassian. Someone’s bank manager is very happy tonight.

I just grabbed the text from a mail I got from The Browser Company.

Dear Arc Members,

Josh here, with some big news we’re excited to share:
The Browser Company of New York has entered into an agreement to be acquired by Atlassian.

From the very beginning, the Atlassian team have been among Arc’s biggest fans - their CEO Mike was actually one of our earliest bug reporters! He and the team believe in the browser’s possibilities just as deeply as you do.

But this note is really about you.

You’ve been with us from the start, too. You’ve sent feedback, shared notes with me directly, shown off your Space themes, and convinced friends to rethink the internet. Arc exists because of you, and I’ll never stop being grateful.

Here’s what this new chapter means for you:
• Arc and Arc Search will continue to exist; we’ll share a long-term plan soon. The Atlassian team loves Arc and has a Slack channel with 1,000+ Arc fans!

• We’re growing Dia, our AI browser. With Atlassian’s support, we’re focused on Dia - building for more platforms, pushing the boundaries of AI browsing further, and weaving in many of the workflows you love in Arc. If you’re curious, you can try Dia with your Arc email.

• Same team, same way of building. We’ll keep our NYC HQ, culture, creativity, and heartfelt intensity. Only difference is more support to go further, faster.

This is the start of a new chapter for Arc, Dia, and The Browser Company. Thank you, thank you, thank you for being the ones who made it possible.
You can read more of my thoughts here on Substack, Twitter and hear from Atlassian’s CEO Mike here.

Happy browsing,
Josh & The Browser Company Team

This looks like good news for us that has been hanging on and expecting a bitter end. :joy:

I only hope that Arc will not be swallowed into some corporate solution. I have seen good software vanish beyond reach for personal use before.

It’s a very interesting announcement, i.e., the sort that makes you wonder what you missed. The $610 million valuation is very surprising for a company that I had been assuming to be on its way to the corporate graveyard, despite having some interesting technology.

I also have a lot of respect for Atlassian. They aren’t perfect, and their products (Jira, Confluence, Bitbucket, etc.) can be expensive, but they really are workhorses for many companies, including my last company. As noted earlier, Trello also is interesting for agile project tracking and management. I suppose I need to spend more time thinking about how “the browser is the new operating system” and how all these pieces fit together.

Best wishes to all involved.

Having had the Atlassian products foisted upon me I can’t see anything good about this acquisition.

I liked Arc. I used Arc. Then I felt they pulled the rug out from under me for Dia, an app that gave features I don’t want or need. Now they sold out and pivoted to enterprise. I don’t see how any of this has me, an end-user, in mind. Good on them for getting $610 million, though. I’m back to Safari + Brave.

I think The Browser Company, in its last round of funding before the acquisition, had a valuation of something like $550mm. When coupled with Perpexity’s recent bid for the Google Chrome browser of $35.5 billion and the premium acquirers usually pay, I’m sure TBC’s prior investors, merger advisors, Board, and management smelled blood in the water.

—————
ETA: since Atlassian was an investor in TBC and the acquisition was all cash, Atlassian may have been less price sensitive than a non-investor acquirer because Atlassian will, in effect, get a rebate on the purchase price and also avoid any accounting effects of a merger taking place for less than the most recent funding round valuation.

I have to agree with the general sentiment. Considering Atlassian, this to me seems to be a continuation of a downward slide rather than any good news.

The most charitable take is that they rescued Arc out of the goodness of their hearts and expect to make money from Dia somehow.

But after the Arc rugpull I don’t trust their direction, and I don’t trust Atlassian to make it any better.

I agree; that language was attributed to the founder, who understandably would love to continue on the same path they chose. The contrarian view is they spent a lot of startup capital making their development team very happy and creating a Silicon Valley-like work environment centered in Brooklyn.

I don’t believe Atlassian will be having that. As you’ve said they have shipped three effective tools in the past decade or so, and I’ll also note that their marketing is public and noticeable. My guess is that they have recognized the Arc paradigm as a way to bridge their management and productivity tools with the Web and (perhaps) judiciously applied AI.

Fella can dream, yes?

Company I work with moved from Jira/Confluence to GitHub Projects/issues/Wiki, saved us a ton of cash. Add BitBucket to this, moved from it, supports only Linux runners in pipes, while GitHub actions offer macOS and Windows in addition.

What I am curios about is the fate of Swift WinRT.
