Who Is Daniela Amodei? Anthropic's President, Co-Founder and Board Chair

Daniela Amodei is the President, co-founder and board chairperson of Anthropic, the AI company behind Claude, as of November 12, 2026. The company's latest SEC filing lists her age as 39. Before Anthropic she held several roles at OpenAI, including VP of Safety and Policy, and earlier worked in risk management at Stripe. She is one of seven co-founders, alongside her brother, CEO Dario Amodei.

Her titles, career history and share count all come from the amended S-1 prospectus Anthropic filed on November 10, 2026. The company plans to list on Nasdaq under the ANT stock ticker. This profile sticks to that public record: what she does, where she worked before, and what her role means in the IPO.

Key Takeaways

• She holds a B.A. in English Literature from UC Santa Cruz.
• She owned 241,408,940 Anthropic shares as of September 30, 2026, and plans to sell 3,378,378 in the IPO.

What Does Daniela Amodei Do at Anthropic?

Daniela Amodei is Anthropic's President and the chairperson of its board of directors. She has held the President and director roles since the company was co-founded in January 2021. The filing lists her as one of three executive officers, next to CEO Dario Amodei and CFO Krishna Rao.

As chairperson, she leads a board of six. Anthropic's company page names the directors as Dario Amodei, Daniela Amodei, Yasmin Razavi, Reed Hastings, Chris Liddell and Vas Narasimhan. Hastings, a co-founder of Netflix, is the lead independent director.

That board works under unusual rules. Anthropic is a public benefit corporation, so its directors must weigh three things: the financial interests of stockholders, the people its conduct affects, and the public benefit written into its charter. A separate body, the Long-Term Benefit Trust, elects the directors who will hold a majority of board seats.

She also has a second governance job. Daniela Amodei, Dario Amodei and co-founder Jack Clark are the initial managers of the Anthropic Public Benefit Fund. The fund is a company subsidiary that holds 846,840,960 non-voting shares set aside for Anthropic's public benefit purpose.

The company she helps run has grown fast. The filing counts about 5,300 employees and says all seven co-founders remain active leaders.

What Did Daniela Amodei Do Before Anthropic?

Before Anthropic, Daniela Amodei spent about two years at OpenAI and five years at Stripe. Her roles were in risk, people management and policy, not AI research. That sets her apart from several other co-founders: three of them hold doctorates in physics or biophysics.

The filing gives her career in three steps:

• Stripe, May 2013 to July 2018: Risk Manager at the payments company.
• OpenAI, October 2018 to December 2020: several roles, including Engineering Manager, VP of People, and VP of Safety and Policy.
• Anthropic, January 2021 to today: President, director and chairperson of the board.

Daniela Amodei's education is in the humanities. She holds a B.A. in English Literature from the University of California, Santa Cruz.

She left OpenAI in December 2020, the same month as her brother. How the two companies' paths to public markets differ is covered in MEXC's comparison of the Anthropic and OpenAI IPO plans.

How Are Daniela and Dario Amodei Related?

Daniela and Dario Amodei are siblings. They are two of Anthropic's seven co-founders, and the only two co-founders who sit on its board. Dario runs the company as Chief Executive Officer. Daniela is President and chairs the board.

Their careers crossed at OpenAI. Dario was VP of Research there from July 2016, and Daniela joined in October 2018. Both left in December 2020 and co-founded Anthropic the following month with five former OpenAI colleagues: Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah.

Their ownership is close to equal. Daniela beneficially owns 241,408,940 shares and Dario 240,637,980. They also share duties outside the executive team, since both are initial managers of the Public Benefit Fund.

The split of titles is the clearest public description of how Dario and Daniela Amodei divide the work. One sibling is the chief executive. The other is the president and leads the board that oversees the company.

What Is Daniela Amodei's Role in the Anthropic IPO?

Daniela Amodei is both a selling stockholder and part of the group that will control Anthropic after the IPO. She owns 241,408,940 shares, plans to sell 3,378,378 of them in the offering, and has agreed to a lock-up of up to 365 days on the rest. She has also pledged 80% of her Anthropic equity to philanthropy.

The offering itself is large. Anthropic and its selling stockholders plan to offer 825,000,000 Class A shares at $70 to $78 each, a range explained in MEXC's guide to the Anthropic IPO price per share.

Based on 13,086,672,593 shares outstanding after the offering, that range would give Anthropic a market cap of about $916.1 billion to $1.02 trillion.

Her own sale is small next to her stake. The 3,378,378 shares are about 1.4% of what she holds, and each of the seven co-founders is selling the same number. Together those 23,648,646 shares are all of the stock being sold by existing holders. The other 801,351,354 shares come from the company.

At the $74 midpoint of the range, her stake would be worth about $17.9 billion on paper, and the shares she is selling about $250 million.

Two commitments shape what happens after listing. The lock-up period keeps the co-founders from selling their remaining shares for up to 365 days after the prospectus date, longer than the 180 days that applies to most other holders. The filing also says each co-founder has pledged 80% of their personal Anthropic equity to philanthropic causes.

Control is a separate matter from share count. The seven co-founders hold a single Class F share through a Founder LLC, and that one share carries 50.1% of the general stockholder vote. The mechanics are set out in MEXC's breakdown of what the Anthropic IPO prospectus says about control.

Timing is still open. Anthropic has not announced a pricing date or a first trading day, and media reports pointing to the week of November 16 are unconfirmed. MEXC's page on the Anthropic IPO date and current status tracks what is official. Filing updates as they happen are logged in MEXC's Anthropic IPO news tracker.

For the wider picture of who holds what, MEXC's guide to Anthropic's IPO valuation and ownership covers the funding rounds and major holders. How access to the offering works for individuals is a different topic, set out in the walkthrough on how the Anthropic IPO allocation process works.

MEXC View: What Does Daniela Amodei's Role Say About Anthropic's Governance?

In our view, Daniela Amodei is the co-founder most worth understanding for anyone asking how Anthropic will be run after the IPO. Most coverage centers on her brother. The board she chairs is where the company's checks actually sit.

That board has a feature governance-minded investors often ask about. The chief executive and the board chair are both co-founders, and they are siblings.

Anthropic's answer is two counterweights. Reed Hastings serves as lead independent director, and the Long-Term Benefit Trust elects the directors who will hold most of the board seats.

We think both sides deserve weight. Founder control and a family pairing at the top can keep a company pointed at a long-term mission. The same structure leaves Class A holders with a limited say, capped at 49.9% of the vote.

Her background adds a practical angle. Risk work at Stripe and people and policy roles at OpenAI are operating experience, and they fit a President's job of running the company rather than its research.

What we will watch: the final board line-up at pricing, and whether the chair role changes after listing. None of this is a view on the stock's price.
