Daniela Amodei
Co-founder, President and Board Chair, Anthropic
Who is Daniela Amodei
Daniela Amodei is a co-founder and the president of the AI company Anthropic[1]. She has been president and a board member since she co-founded Anthropic in January 2021, and Anthropic's November 2026 IPO filing says she now also chairs its board[1]. Fortune says her duties as president include safety and trust[6].
She told Stanford Graduate School of Business that Anthropic takes "radical responsibility" for its technology[4]. In that talk she named catastrophic risks such as chemical and biological weapons and cyberattacks, and everyday issues such as user wellbeing, child safety, misinformation and election integrity[4].
Education and early career
Amodei graduated from the University of California, Santa Cruz in 2009[3]. She holds a B.A. in English Literature, and UC Santa Cruz says she also took a minor in politics[1][3]. In April 2026 UC Santa Cruz quoted her: "I actually think studying the humanities is going to be more important than ever"[3].
She began her career in international development and global health, then worked on Capitol Hill and on a political campaign[4].
She joined the payments company Stripe in 2013 as a founding recruiter, according to Forbes[5]. Anthropic's S-1 says she was a risk manager, among other positions, at Stripe from May 2013 to July 2018[1]. She told Stanford GSB that she stayed almost six years at a company that "nobody had heard of" when she joined[4].
OpenAI
Amodei held several positions at OpenAI between October 2018 and December 2020[1]. They included vice president of safety and policy, vice president of people, and engineering manager[1].
She left OpenAI in December 2020[1]. She told Stanford GSB that seven people originally left: she, her brother Dario and their five co-founders[4]. She said the group was "running towards something versus running away from something"[4].
Co-founding Anthropic
Anthropic was founded in January 2021[1]. Its S-1 names seven co-founders: Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah[1]. TechCrunch reported the company's launch and $124 million in funding in May 2021[7].
Her older brother Dario Amodei is Anthropic's chief executive, and she is its president[1]. The founders made Anthropic a public benefit corporation[4]. Its board is elected by stockholders together with a Long-Term Benefit Trust[8].
In February 2026 Anthropic raised money at a $380 billion valuation and said its run-rate revenue was $14 billion[9]. Forbes says private investors valued the company at $965 billion in May 2026[5].
Anthropic's IPO filing
Anthropic filed a registration statement (Form S-1) to go public on 26 October 2026[2]. It filed its second amendment on 10 November 2026[1]. The filing says the shares will list on the Nasdaq Global Select Market under the symbol "ANT"[1].
The filing gives Amodei's title as President, Co-Founder, Chairperson, and Director[1]. As chair she will preside over meetings of the board and of stockholders and advise the chief executive[1]. Reed Hastings is the board's lead independent director[1].
The amended S-1 lists her as the beneficial owner of 241,408,940 Class A shares, 3.6% of the company before the offering, and as a selling stockholder of 3,378,378 shares[1]. Her total 2025 pay was $16,408,998, mostly the grant-date value of options and restricted stock units, with a salary of $654,167[1]. The seven co-founders will initially be the only members of a Founder LLC, which will hold a single Class F share[1].
Family
Daniela and Dario Amodei are siblings[1]. Anthropic's S-1 says there are no other family relationships among its executive officers or directors[1]. She was born in San Francisco in 1987[11]. The S-1 gives her age as 39 and Dario's as 43 on 31 October 2026[1].
Her husband is Holden Karnofsky, and they married in August 2017[11]. Karnofsky co-founded Open Philanthropy and sat on OpenAI's board from 2017 to 2021[10]. He joined Anthropic in January 2025 as a member of technical staff working on safety planning[10]. The S-1 confirms that he is her spouse and has worked at Anthropic since January 2025[1]. Forbes lists her as married with two children[5].
