**The Browser Company**, legally The Browser Company of New York, Inc., is an American software startup that builds [web browsers](/wiki/web_browser). Founded in 2019 and headquartered in New York City, it first gained attention for Arc, a widely praised but niche reimagining of the desktop browser released in 2023, and later pivoted to [Dia](/wiki/dia_browser), an AI-native browser with a built-in assistant that can read and act on the contents of a user's open tabs. [1][2] In September 2025 the Australian enterprise-software company [Atlassian](/wiki/atlassian) agreed to acquire The Browser Company for approximately $610 million in cash; the deal closed on October 21, 2025, making The Browser Company a wholly owned subsidiary while founders Josh Miller and Hursh Agrawal stayed on to lead the unit. [3][4]

## Overview

The Browser Company positions itself as a product-design house focused on rethinking the browser, the piece of software through which most knowledge work now happens. Its thesis, repeated across its public communications, is that mainstream browsers such as Google Chrome were "built for browsing" rather than for work, and that the arrival of large language models created an opening to rebuild the browser around an AI assistant. [3][4] The company shipped two distinct products under this thesis: Arc, a heavily reworked traditional browser aimed at power users, and Dia, an [AI browser](/wiki/ai_browser_agent) built around a conversational assistant. Both were built on Chromium, the open-source project that also underlies Chrome and Microsoft Edge. [2]

The company is small relative to the incumbents it competes with, and its trajectory, from a beloved cult product (Arc) to a strategic pivot (Dia) to acquisition by a larger enterprise vendor, has made it a frequently cited example of the 2025 wave of AI-browser activity. [1][5]

## Founding (Josh Miller)

The Browser Company was founded in 2019 by Josh Miller, who serves as chief executive officer, and Hursh Agrawal, who serves as chief technology officer. [3] Miller had previously been a product director at Facebook, which acquired his earlier startup Branch in 2014, and he later worked in the Obama administration as a director of product on the White House Office of Digital Strategy. [6] Before starting The Browser Company full time, Miller spent time at the venture firm [Thrive Capital](/wiki/thrive_capital), founded by Josh Kushner, as an entrepreneur in residence and then as an investor, leaving in 2020 to focus on the new company. [6]

Miller and Agrawal assembled a team around the conviction that the browser had stagnated even as the web became the primary surface for daily work, and they spent the company's early years in a long, deliberately quiet development period before releasing anything publicly. [1][6]

## Arc browser

Arc, the company's first product, was previewed via a Twitter announcement on April 19, 2022, and entered a closed, invite-only beta before a public macOS release on July 25, 2023. [2] A Windows version followed on April 30, 2024, and the company also shipped companion mobile experiences, including an iOS app and later the AI-assisted Arc Search. [2]

Arc reimagined the browser interface around a left-hand sidebar in place of a traditional horizontal tab strip, with features such as "Spaces" for grouping tabs by context, pinned and automatically archived tabs, and split-view browsing. The browser drew strong praise from technology reviewers. David Pierce of The Verge wrote that Arc was "full of big new ideas about how we should interact with the web," and other critics described it as the most refined recent attempt to rethink the browser, though some noted a steep learning curve. [2] Despite enthusiastic reviews and a devoted user base, Arc remained a niche product, and its unconventional design was widely seen as a barrier to mainstream adoption. [1][2]

In October 2024 Miller announced that a planned "Arc 2.0" redesign had been shelved and that the company would maintain Arc's existing feature set rather than continue major development. [2] On May 27, 2025, Miller published a longer note explaining that the company was discontinuing active feature development on Arc to concentrate entirely on its new AI browser, Dia, while pledging to keep Arc maintained for security and stability. [2] A separately disclosed security vulnerability, found in September 2024 and subsequently patched, had allowed certain accounts to be targeted for arbitrary code execution; the incident factored into the company's broader reassessment of Arc. [2]

## The pivot to Dia (AI browser)

Dia is The Browser Company's AI-native browser. The company opened a public beta on June 11, 2025, initially limited to existing Arc members and people invited through the beta. [5] Rather than reorganize the tab interface as Arc did, Dia places a large language model at the center of the browsing experience: users can type natural-language queries into the address bar, chat with a right-hand sidebar assistant about the contents of their open tabs, and create reusable prompt shortcuts the company calls "Skills." The assistant can summarize pages, draft text, and compare information across tabs without the user leaving the page. [5]

The pivot reflected Miller's stated belief that AI represented a larger opportunity than the interface innovations embodied in Arc, and that an assistant capable of acting on web content was the more durable bet. [1][5] The shift was not without friction with Arc's loyal users, some of whom objected to the de-emphasis of a product they valued, and the episode became a widely discussed case study in startup focus and product strategy. [1]

## Funding

Before its acquisition, The Browser Company raised roughly $68 million in venture funding across several rounds. [3][7] It closed a seed round of about $5 million in 2020 and a Series A of about $13 million in 2021. [7] In March 2024 it raised a $50 million Series B led by Pace Capital at a valuation of approximately $550 million. [7]

| Round | Date | Amount (approx.) | Notes |
| --- | --- | --- | --- |
| Seed | 2020 | $5 million | Early backing |
| Series A | 2021 | $13 million | |
| Series B | March 2024 | $50 million | Led by Pace Capital; ~$550M valuation |
| Total raised | (pre-acquisition) | ~$68 million | |

Investors and angels associated with the company included Pace Capital, BoxGroup, NextView Ventures, and Atlassian Ventures, along with individual backers such as Figma chief executive Dylan Field, former LinkedIn chief executive Jeff Weiner, Notion executive Akshay Kothari, former GitHub chief technology officer [Jason Warner](/wiki/jason_warner), and Twitter and Medium co-founder Ev Williams. [3][7]

## The Atlassian acquisition

On September 4, 2025, [Atlassian](/wiki/atlassian), the maker of enterprise products such as Jira and Confluence, announced a definitive agreement to acquire The Browser Company for approximately $610 million in cash, inclusive of the startup's existing cash balance, funded from Atlassian's balance sheet. [3][8] Atlassian co-founder and co-chief executive Mike Cannon-Brookes framed the rationale around building "a browser designed for the specific needs of knowledge workers in the AI era," arguing that existing browsers "weren't built for work, they were built for browsing." [3] Reporting at the time of the deal indicated that OpenAI and Perplexity had also explored acquiring the company. [9]

Atlassian completed the acquisition on October 21, 2025. [4] Under the transaction, The Browser Company became a subsidiary of Atlassian, with Josh Miller continuing as chief executive officer and Hursh Agrawal as chief technology officer of the unit, and Dia positioned to be integrated with Atlassian's collaboration and enterprise software. [4] The acquisition was part of a broader surge in technology mergers and acquisitions during 2025. [9]

## Significance

The Browser Company is frequently cited as a leading example of the 2025 shift toward AI-native browsing, in which the browser is reconceived as an agent that can read pages and act on a user's behalf rather than merely display them. [1][5] Its story compresses several themes of that period: the difficulty of converting critical acclaim into mass adoption (Arc), a high-profile pivot from a beloved product to an AI-first successor (Dia), and the absorption of a consumer-facing AI startup into a larger enterprise-software vendor (Atlassian). [1][3]

The company built and shipped Dia into an intensely competitive field. Direct rivals include [Perplexity Comet](/wiki/perplexity_comet), launched in July 2025; [ChatGPT Atlas](/wiki/chatgpt_atlas), OpenAI's browser released in October 2025; Google Chrome with its [Gemini](/wiki/gemini) assistant built in; and [Microsoft Copilot](/wiki/microsoft_copilot) Mode in the Edge browser, introduced in October 2025. [10] Within Atlassian, Dia's competitive position is increasingly oriented toward enterprise knowledge work rather than the broad consumer market those rivals chase, distinguishing it from Arc's earlier, more general-purpose ambitions.
