MITCHELL BAKER

Baker grew up in Berkeley, California, and trained as a lawyer. She joined Netscape in 1994 as one of the company's early internet lawyers — one of the first people hired specifically to navigate the legal chaos of building internet businesses before anyone had a playbook.

In 1998, when Netscape announced it would open-source its browser code, Baker was one of the key people who made the transition real. The project that emerged — eventually called Mozilla — was chaotic for years.

Netscape was bleeding. AOL acquired it.

The code was a mess. Baker stayed.

In 2003, she co-founded the Mozilla Foundation as a nonprofit to properly own and steward the Mozilla project. It was an unusual structure: a charity running a browser in an industry full of companies trying to monetize every click.

Critics said it could not compete. The product proved otherwise.

Firefox 1.0 launched on November 9, 2004. It had been beta-tested by millions and built largely by volunteers.

Within 12 months it had 100 million downloads. Firefox 3.0 in June 2008 set a Guinness World Record with 8 million downloads in a single day.

At its peak around 2010, Firefox held over 30% of the global browser market. That is what it looks like when an open-source nonprofit beats a corporate giant at its own game.

Baker stepped back from the CEO role in 2020 as Mozilla went through significant layoffs — around 250 people, roughly 25% of staff — and grappled with revenue concentration from the Google search deal. She returned to the CEO role in 2022 as Mozilla tried to find its next chapter in the AI era.

Mozilla Foundation is the California nonprofit Baker spent decades building. It exists to promote internet health, open-source development, and the principle that the web should serve people rather than exploit them.

The structure was deliberate from the start: a nonprofit parent that owns a taxable subsidiary (the Mozilla Corporation) which actually builds and ships Firefox and other products.

Firefox at its peak was one of the most important pieces of software in the world. It broke Internet Explorer's stranglehold on the browser market, forced Microsoft to resume development of IE (which had stagnated since winning the first browser war), and proved that open-source projects could build consumer-grade products at global scale.

It was downloaded over a billion times.

Mozilla Corporation ships Firefox as well as Firefox Focus (the privacy-first mobile browser), Pocket (the read-later service acquired in 2017), and various AI-focused tools Mozilla has been developing since 2023. Mozilla Ventures was also launched under Baker's leadership to invest in startups building responsible technology.

Netscape is where the whole story started. Baker joined in 1994 as one of their early internet lawyers and worked on the licensing agreements that helped Navigator spread across the web.

When Netscape decided to open-source its browser in 1998, that decision led directly to Mozilla, which led to Firefox, which changed the internet.

Baker's investing approach through Mozilla Ventures is explicitly mission-driven. The focus is startups building privacy-first products, ethical AI tools, and technology that gives users more control over their digital experience.

It is not traditional venture capital — it is capital deployed with a defined worldview about what technology should and should not do.

Firefox at its peak (around 2010) had over 30% of the global browser market. A nonprofit product built largely by volunteers beat one of the most powerful companies in the world at its own game.

Nothing else Baker has done comes close to that as a demonstration of what open-source and mission-driven development can actually achieve.

Losing the mobile browser war. Firefox OS — Mozilla's attempt to build a mobile operating system for smartphones — launched in 2013 and failed to gain meaningful adoption.

It shut down in 2016. By then, Chrome had already won mobile, and Mozilla never recovered meaningful market share in the segment that now accounts for the majority of browsing.

Technology should be accountable to users, not advertisers or shareholders. Baker has argued consistently that ad-funded internet models create misaligned incentives.

The irony is that Mozilla's primary revenue source for years has been Google paying hundreds of millions annually to be Firefox's default search engine — a tension she has had to live with publicly.

Based in Berkeley, California. She is a public figure but keeps her family life private.
