Who Is Daniela Amodei?
Daniela Amodei is the president and co-founder of Anthropic, an AI safety company headquartered in San Francisco and the maker of Claude, one of the most widely used large language model families in the world alongside ChatGPT and Gemini. She is 38 years old, born in 1987 in San Francisco, and shares the company’s leadership with her older brother Dario Amodei, who serves as CEO.
Her role at Anthropic covers what most outsiders never see, finance, go-to-market, enterprise sales, recruiting, policy, security, and the day-to-day operating engine of a company that grew from a small spinout to roughly 2,500 employees with a reported $30 billion run-rate revenue by April 2026. Dario sets the research direction; Daniela runs the business and the safety organization that translates research into deployable product.
She is also one of the most influential women in the AI industry. Time named her to its inaugural 100 Most Influential People in AI list in September 2023, jointly with Dario, and added her to the broader Time 100 Most Influential People list on April 20, 2026. In the 2026 profile, she said:
“I ultimately believe in a world where AI is very smart and capable of doing so many things, the things that make us human will become much more important.”
Daniela Amodei’s Early Life and Education
Daniela Amodei grew up in San Francisco. Her father, Riccardo Amodei, was an Italian American leather craftsman from Massa Marittima in Tuscany. Her mother, Elena Engel, was a Jewish American born in Chicago who worked as a project manager for libraries. Daniela’s older brother Dario would go on to become the CEO of Anthropic; the two grew up in the same household and remained close throughout their careers.
High School
She attended Lowell High School in San Francisco, the public magnet school that has produced a long list of notable alumni from the Bay Area tech and finance world.
UC Santa Cruz (2009)
Daniela enrolled at the University of California, Santa Cruz, where she graduated in 2009 with a Bachelor of Arts in Literature and a minor in Politics. She was also a classical flute player and held a classical flute scholarship while she studied liberal arts and music on campus. UC Santa Cruz still claims her publicly as a distinguished alumna, and after her 2026 Time 100 listing the university issued its own announcement.
That literature-and-music background is not a footnote. Daniela has repeatedly defended humanities majors in tech interviews, telling Fortune in February 2026 that strong communication, emotional intelligence, and the ability to think clearly about people are exactly the skills Anthropic hires for, especially as AI handles more raw analytical work.
Daniela Amodei’s Career Path
Daniela’s path to the top of one of the most valuable AI companies in the world did not start in research. It started in politics.
Politics (early career)
After graduating, she worked on a congressional campaign in Pennsylvania, then briefly managed communications for Representative Matt Cartwright in Washington, D.C. She left politics for the tech industry shortly after, drawn to operational and product work she felt would scale faster than legislative work.
Stripe (2013–2018)
In 2013, Daniela joined Stripe as an early employee, when the payments company was still small but growing rapidly. She spent roughly five years at Stripe, building experience in operations, risk, and people management, the foundation of every role she has held since.
OpenAI (2018–2020/2021)
She joined OpenAI in 2018, initially managing the team that built GPT-2, OpenAI’s first widely discussed large language model. She then moved into safety and policy work, eventually rising to Vice President of Safety and Policy, the senior role she held when she left.
Her departure came in 2020, ahead of Anthropic’s official founding the following year. By that point her brother Dario was also looking for the exit.
Anthropic (2021–present)
In 2021, Daniela and Dario co-founded Anthropic alongside seven former OpenAI colleagues, Jared Kaplan, Jack Clark, Chris Olah, Ben Mann, Sam McCandlish, and Tom Brown. The stated mission was to build AI systems that are safe, interpretable, and honest. Dario took the CEO seat. Daniela became president, owning everything outside of research direction, business operations, policy, security, enterprise sales, hiring, and the company’s safety organization.
Five years later, Anthropic has roughly 2,500 employees, a $380 billion post-money valuation (Series G, February 2026), and a reported $30 billion annualized revenue run rate by April 2026. Talks are underway at a $900 billion pre-money valuation as of May 2026.
Why Did Daniela and Dario Amodei Leave OpenAI?
The most common framing across interviews and press coverage is directional differences over AI safety. The Amodei siblings, along with the seven colleagues who left with them, believed the next generation of AI systems needed to be built around safety from the first day, not bolted on after capabilities had already raced ahead. They wanted constitutional safety principles at the foundation of the work, not in a downstream policy layer.
That conviction became the core of Anthropic’s identity, and it is the reason the company introduced ideas like Constitutional AI and the Responsible Scaling Policy that the industry has since copied. Daniela has consistently framed this in public as a question of trust. In her telling, trust is what unlocks deployment at scale. In regulated industries, the question is not which model is smartest but which model a company can actually rely on.

Personal Life: Husband, Children, and Family
This is the section that gets misread the most online, so we are going to keep it tight.
Husband: Holden Karnofsky
Daniela Amodei has been married to Holden Karnofsky since August 2017. Karnofsky is the co-founder of GiveWell (2007) and Open Philanthropy (2014, now operating as Coefficient Giving), two of the most influential organizations in the effective altruism movement. He was born around 1980 and has been a central figure in EA philanthropy for nearly two decades.
In January 2025, Karnofsky joined Anthropic as a member of the technical staff, working on responsible scaling policies and long-term safety planning. He reports to Chief Science Officer Jared Kaplan. The hire was first reported by Fortune in February 2025 and added a third member of Daniela’s immediate family to Anthropic’s payroll.
Children
Daniela and Holden have one son, named Galileo. He was born before 2023; the family has kept further details private.
Parents and Heritage
Her father Riccardo Amodei was Italian American, from Tuscany, and worked as a leather craftsman. He passed away when Daniela was a young adult after years of health issues. Her mother Elena Engel is Jewish American, born in Chicago, and worked as a project manager for libraries. That dual Italian-Catholic and Jewish-American heritage is the basis of the many “daniela amodei ethnicity” and “daniela amodei religion” queries that show up in search.
Where they live
They live in the San Francisco Bay Area and has spoken in interviews about morning time with her husband and son before her work day begins.
Daniela Amodei Net Worth (2026)
Daniela Amodei’s net worth is real but hard to pin to a single number, because Anthropic is privately held and her exact equity stake has never been disclosed. The most-cited estimates as of 2026:
| Source | Estimate | Date |
|---|---|---|
| Forbes | ~$7 billion | February 2026 |
| Hurun Global Rich List | ~$3.6 billion (¥26 billion) | March 2026 |
| Celebrity Net Worth | ~$1.2 billion | 2026 |
The spread reflects three things, different assumed equity percentages, different liquidity discounts on private-company stock, and the fact that Anthropic’s valuation has moved sharply across 2025 and 2026. If the rumored $900 billion funding round closes in 2026, every one of these estimates will be revised upward.
For context, Anthropic itself raised a $30 billion Series G at a $380 billion post-money valuation in February 2026, with major backers including Amazon (~$8 billion total committed across 2024 and 2025) and Google (~$2.5 billion across multiple tranches).
Recognition and Public Profile
Daniela’s public recognition has tracked Anthropic’s rise. Time named her to its inaugural 100 Most Influential People in AI list in September 2023, jointly with Dario, and added her to the broader Time 100 Most Influential People list on April 20, 2026, a listing UC Santa Cruz publicly recognized as well. She also speaks regularly at Stanford, Fortune, and Sixth Street investor conversations on AI strategy and enterprise trust.
She is not a frequent tweeter or media personality. Her public profile is built almost entirely through long-form interviews, conference talks, and policy work, not social media.
Conclusion
Daniela Amodei is one of the most consequential operators in modern AI, the person who runs the business and safety machine that turns Anthropic’s research into the Claude models powering everything from coding assistants to enterprise deployments. She is not Anthropic’s most public face, that is her brother Dario, but she is the reason the company can scale, hire, sell, and stay coherent on safety while doing it.
