Daniela Amodei (born 1987) is an American business executive, the President and a co-founder of Anthropic, the artificial intelligence company that develops the Claude family of large language models. She founded the company in 2021 with her brother Dario Amodei, who serves as chief executive, after both left OpenAI along with several colleagues. As President, she oversees Anthropic's commercial, operations, finance, legal, communications, and people functions, leaving research direction largely to her brother and Anthropic's chief scientists. By 2025 she had become one of the most prominent female executives in generative AI, named to the TIME 100 AI list and to Fortune's Most Powerful Women ranking.

Daniela Amodei was born in 1987 in San Francisco, California. Her father, Riccardo Amodei, was an Italian American leather craftsman from Massa Marittima in Tuscany, and her mother, Elena Engel, was a Jewish American from Chicago who worked as a project manager for libraries. Her father died when she was a young adult after a long illness. She grew up in San Francisco and attended Lowell High School, the city's selective public school, before going on to college.
She received a classical flute scholarship to the University of California, Santa Cruz, and graduated in 2009 with a Bachelor of Arts in English literature and a minor in politics. While at UC Santa Cruz she won the campus Concerto Competition in 2008, performing as a soloist with the university's orchestra. Her older brother Dario, who would later co-found Anthropic with her, studied physics and biology at Stanford and Princeton during the same period.
Daniela's path into the technology industry was indirect. Although her brother went into computational neuroscience and machine learning, her early interests were in literature, languages, music and politics, which would later shape her view of AI as a humanistic problem as much as a technical one. In a 2026 conversation she argued that humanities graduates are underrated for jobs in AI because so much of the work consists of writing, communication, and reasoning under ambiguity.
After college, Amodei spent several years working in international development and global health in roles she has described as small program management jobs in low income countries. The experience left her interested in policy and politics, which led her to a Pennsylvania congressional campaign in 2012.
She joined the campaign of Matt Cartwright, a Democratic challenger running for a House seat in northeastern Pennsylvania, as a field organizer and later deputy field director. She personally recruited volunteers and ran door knocking and phone banking operations in the district. After Cartwright won the seat, she followed him to Washington, D.C., where she worked briefly in his congressional office handling scheduling and legislative correspondence in the first half of 2013. She left politics for the technology industry later that year.
In 2013, Amodei joined the payments company Stripe as an early employee. She started as the company's first non founder recruiter and was tasked with hiring engineers and operators as Stripe scaled from a small startup into one of the more visible fintech firms of the decade. Over the next several years she moved through a series of operational roles at Stripe, including technical recruiting lead, risk program manager and then risk manager, where she worked on user policy and underwriting decisions. By the time she left she had spent roughly five years at the company and had touched recruiting, trust and safety, and operations.
In 2018 Amodei left Stripe and joined OpenAI, the San Francisco AI research laboratory then transitioning from a nonprofit lab into a hybrid capped profit organization. Her brother Dario had joined OpenAI a couple of years earlier and would soon become its Vice President of Research. She joined initially as an engineering manager, then took on broader operational responsibilities, eventually becoming Vice President of Safety and Policy.
In that role she helped build the processes by which OpenAI evaluated whether to release new models. She managed teams during the development of GPT-2 and GPT-3, including the staged release of GPT-2 in 2019, which OpenAI initially declined to fully open source on safety grounds and which became one of the first public debates about model release norms in modern AI. The processes she helped set up, including red teaming, model cards and policy review before deployment, became templates that other AI labs later adopted.
By late 2020, Daniela, her brother and several of their closest colleagues at OpenAI had grown uncomfortable with the lab's direction, particularly the speed of commercialization following the Microsoft partnership and disagreements over how safety and product strategy should interact. Together they decided to leave and start a new company.
Anthropic was incorporated in early 2021. The company was registered in California as a public benefit corporation in February 2021, with seven co-founders: Daniela Amodei, her brother Dario Amodei, Tom Brown, Sam McCandlish, Jared Kaplan, Jack Clark, and Chris Olah. All seven had been senior figures at OpenAI; Tom Brown had been a lead author on the original GPT-3 paper, Jared Kaplan was known for the neural scaling laws work, Jack Clark had run policy, and Chris Olah was a leading interpretability researcher. Several other early employees, including Ben Mann, came over from OpenAI in the same wave and are sometimes described as part of the founding cohort.
From day one, Daniela took on the President role while Dario became chief executive. The split has been described, including by both siblings in interviews, as a deliberate division of labor: Dario sets research direction and writes about AI policy and risk, while Daniela runs the company. In practice that has meant she owns operations, finance, legal, communications, recruiting, real estate, security and the commercial organization, while research, model development and safety research report up to Dario.
Anthropic positioned itself from the start as an AI safety company. Its stated mission is to do research on and build safe AI systems, and the founders argued that being at the frontier of capability was necessary in order to study frontier risks. The company chose to incorporate as a public benefit corporation, and in 2023 it created the Long Term Benefit Trust, a separate body of trustees with the legal power to elect a portion of the board, intended to act as a counterweight to short term commercial pressure.
As President, Amodei runs the day to day operations of Anthropic. She has described her remit as the President's portfolio, covering operations, strategy execution, partnerships, finance, legal, security, communications, recruiting and culture. The research organization, including pretraining, alignment, interpretability and the safety teams, reports through her brother and through chief scientists Jared Kaplan and Sam McCandlish.
Under her watch, Anthropic has grown from a small research lab of a few dozen people in 2021 into a company with thousands of employees by 2025. She has overseen the build out of Anthropic's go to market organization, its enterprise sales arm, its partnerships with Amazon, Google, Microsoft and Salesforce, and the international expansion of the company into Europe and Asia. She has also been the public face of the company on hiring, organizational culture and the question of how to structure an AI lab that takes safety seriously while competing in a market that rewards speed.
Under Amodei's tenure as President, Anthropic raised one of the largest sequences of private financing rounds in technology history. The company raised an early round of around 124 million dollars in 2021, then a 580 million dollar round in 2022 that included a now infamous investment from FTX. Beginning in 2023, Amazon committed up to 4 billion dollars in a strategic investment that was later expanded to 8 billion dollars by November 2024, and Google committed more than 2 billion dollars over a similar period. The pace of funding accelerated in 2025.

| Series F | September 2025 | $13 billion | $183 billion |
| Series G | Early 2026 | Reported about $30 billion | Reported about $380 billion |
The company's run rate revenue is reported to have grown from roughly 100 million dollars in late 2023 to about 1 billion dollars at the start of 2025, then to more than 5 billion dollars by August 2025, driven by enterprise sales of the Claude API and consumer subscriptions to Claude.ai. By 2025 Amodei was widely described in the press as one of the few female executives at the helm of a frontier AI company. Forbes added her to its billionaires list, with estimates of her stake placing her wealth in the multibillion dollar range, although the precise figure has fluctuated as Anthropic's valuation has changed.
Amodei has become a regular speaker at industry conferences, on podcasts, and in print interviews, and her public remarks tend to cluster around a few themes.
The first is responsible scaling. In 2023, Anthropic published its Responsible Scaling Policy, a framework that defines AI Safety Levels (modeled loosely on the biosafety levels used in life sciences research) and commits the company to specific safety evaluations and mitigations before deploying models above each level. Amodei has defended the policy in interviews as a way of making safety commitments concrete and externally checkable rather than aspirational, and she has urged other frontier labs to publish similar policies.
The second is the idea of safety as a commercial advantage. In multiple interviews she has argued that enterprises buying AI care about reliability, predictability and risk, and that a lab that invests in interpretability, evaluation and alignment can win business precisely because its models behave more consistently. She has used this argument to push back against the framing that safety and commercial success are in tension.
The third is what she has called doing more with less. In a 2026 interview with CNBC, she described Anthropic's strategy as a deliberate bet that compute efficient research and a smaller, more focused team can outperform much larger competitors. The framing is partly a contrast with the largest labs, which have raised tens of billions of dollars and built giant data centers, and partly a description of how Anthropic actually operates internally.
A fourth recurring theme is hiring and the value of non technical training. She has repeatedly argued in interviews that humanities backgrounds are useful at AI companies, both because much of the work involves writing, judgment and policy, and because frontier AI raises social and philosophical questions that benefit from people trained to think about them. In a 2026 Fortune interview she said studying the humanities would be more important than ever in an AI driven economy.
She has also spoken about the structure of Anthropic itself, including the Long Term Benefit Trust and the company's status as a public benefit corporation, framing both as attempts to design governance that does not collapse under commercial pressure as the stakes get higher.
In August 2017, Daniela Amodei married Holden Karnofsky, a writer and philanthropic strategist who had co-founded the charity evaluator GiveWell with Elie Hassenfeld in 2007 and the grantmaking foundation Open Philanthropy in 2014. Karnofsky was for years the chief executive and then co-chief executive of Open Philanthropy and a prominent figure in the effective altruism movement, writing about AI safety, philanthropy and long term risks on his blog Cold Takes.
In 2025, Karnofsky joined Anthropic in a role focused on responsible scaling and AI safety strategy, a hire that drew attention because of his marriage to the company's President. The couple have one son. They are based in the San Francisco Bay Area.
Daniela's family has been the subject of significant press coverage because of the unusual fact that the President and the CEO of one of the most valuable AI companies in the world are siblings. Both Amodeis have described growing up in a household that took ideas seriously and have credited their parents with encouraging intellectual curiosity.
