Who Is Phoebe Gates? 10 Things on Bill Gates' Youngest Daughter

While Bill Gates may be one of the most recognizable names in tech, his youngest daughter, Phoebe Gates, is steadily carving a name for herself in fashion, activism, and the startup scene.

With her mix of sharp intellect, social awareness, and a designer wardrobe to boot, Phoebe is proving she’s more than just the daughter of billionaires. Here are 10 things to know about the 22-year-old who's navigating life in the spotlight on her own terms.

Phoebe is the third and youngest child of Bill Gates and Melinda French Gates. Born in 2002, she has two older siblings: Jennifer, a medical school graduate and accomplished equestrian, and Rory, a congressional analyst. All three were raised in Seattle and attended Lakeside School, the same high school their father went to.

Phoebe completed her human biology degree at the prestigious Stanford University in just three years, graduating in June 2024. According to her graduation diary, she fast-tracked her coursework to watch her mom deliver the commencement speech as a proud graduate. She marked the day with a family-filled celebration that included her boyfriend, Arthur Donald.

Phoebe’s been making waves with her sleek and modern fashion sense. She’s been spotted at fashion weeks from New York to Copenhagen and regularly steps out in pieces from Chanel, The Row, Prada, and Louis Vuitton. Her style seamlessly blends Gen Z edge with luxury polish.

Along with fellow Stanford alum and her former roommate Sophia Kianni, Phoebe co-founded Phia, a fashion-tech startup aimed at helping people shop smarter and more sustainably. The two even partnered with Stella McCartney to create a capsule handbag collection. The platform is set to launch as a Chrome extension in 2025.

Following in her mother’s footsteps, Phoebe is vocal about reproductive rights and women’s health. She’s spoken at events like Goalkeepers and frequently uses her social media platforms to advocate for body autonomy and access to contraceptives. 

Phoebe is in a relationship with Arthur Donald, the grandson of music legend and Beatle member Paul McCartney. According to People, the Yale grad and venture capitalist has been spotted with Phoebe at several public events, including her graduation party and New York premieres.

Phoebe recently launched a podcast called The Burnouts with Sophia Kianni under Alex Cooper’s Unwell Network. According to the network, the show features weekly guests who dive into topics relevant to Gen Z women entrepreneurs, from pitching investors to workplace dynamics. The show is available in both audio and video formats and has already hosted names like Kim Kardashian and Kris Jenner.

Phoebe appeared in an episode of What’s Next? The Future With Bill Gates, where she discussed online misinformation and its impact on public perception. Their candid conversation included everything from conspiracy theories to social media habits, with Phoebe schooling her dad on why “text me, don’t email me” is the Gen Z way.

Phoebe is not shy about sharing glimpses of her personal life. From bubble-tea outings with her dad to behind-the-scenes moments at fashion shows, she’s building a curated yet relatable social media brand. Her posts often strike a balance between advocacy and aesthetics.

As of April 2025, Phoebe has over 496,000 followers on her Instagram @phoebegates and more than 242,000 on her TikTok @phoebegates. Her content ranges from OOTDs and college life vlogs to activism and family cameos.
