The Wojcicki Sisters: From Silicon Valley Pioneers to a Fight for 23andMe‘s Future
The name Wojcicki is synonymous with Silicon Valley success, and now, a dramatic bid to reclaim control of the DNA-testing company 23andMe has thrust the family back into the headlines. Anne wojcicki, the former CEO of 23andMe, is mounting a $305 million effort to regain control of the company she co-founded, a move that underscores both her entrepreneurial drive and the turbulent fortunes of the once-high-flying biotech firm.
The story of Anne, 51, and her sisters, Janet and Susan, is one of remarkable achievement, nurtured in a supportive Silicon Valley environment. They are known not only for their individual accomplishments but also as a collective force of innovation and leadership.
The three sisters-Anne, Janet, and Susan-were raised in a suburb of Silicon Valley by their mother, Esther Wojcicki, a celebrated educator and parenting expert, and their father, Stanley Wojcicki, a respected physics professor at Stanford University. This upbringing instilled in them a passion for learning and a drive to make a difference, qualities that would define their careers. In 2023, their impact was recognized with a special honor: a line of Barbie dolls designed to inspire young girls to pursue careers in STEM fields.

Anne Wojcicki: The Entrepreneur Battling for 23andMe
Anne Wojcicki earned a B.S. in biology from Yale University in 1996 and, a decade later, co-founded 23andMe with fellow biologist Linda Avey. The company quickly gained recognition for its innovative approach to genetic testing, with its retail saliva-based test being named TIME magazine’s Invention of the Year in 2008.That same period also brought personal changes, as she married Google co-founder Sergey Brin in 2007, and the couple had two children before divorcing in 2015 following reports of Brin’s affair with a Google employee.
23andMe achieved a notable milestone by becoming the first company to receive FDA approval to deliver genetic variant facts directly to consumers. At its peak, the company boasted a market capitalization of $6 billion. Though, the company’s fortunes began to decline following its initial public offering. Rising interest rates impacted consumer spending, and growing concerns about the privacy of its genetic database attracted increased scrutiny. A significant setback occurred in 2023 when hackers breached the system, exposing the personal data of millions of customers over a five-month period. By fall 2024, 23andMe had lost 98% of its value, leading to the resignation of its independent board members and, ultimately, a filing for bankruptcy in March 2025.Shares plummeted 50% to $0.88.

Janet Wojcicki has carved out a distinguished career in academia, serving as a professor of pediatrics and epidemiology at the University of California, San Francisco. She earned her Ph.D. from the University of California, Los Angeles, and her research focuses on early life risk factors for obesity, especially within vulnerable populations.
Beyond her research, Janet has spearheaded the development of longitudinal birth cohorts, studying the impact of nutrition on neonatal outcomes. She also contributes her expertise as a board member for the San Francisco General Hospital Foundation.
Janet’s Research Impact: Her work on early life obesity risk factors has influenced public health policies and interventions aimed at improving child health outcomes.
Susan Wojcicki: From Google Garage to YouTube Leadership
The eldest of the three sisters, Susan Wojcicki, played a pivotal role in the early days of Google. She was the 16th employee at the company, famously renting out the garage of her Menlo Park home as Google’s first headquarters in 1998. Susan’s academic background includes studies in history and literature at Harvard, followed by degrees in economics from the University of California, Santa Cruz, and an MBA from UCLA.
Over her 20-year tenure at Google, Susan was instrumental in launching key products such as google Images, Google Books, and AdSense. She also played a crucial role in Google’s acquisition of YouTube in 2006 and subsequently served as YouTube’s CEO for nine years. In 2023, she stepped down to focus on “family, health and personal projects,” but tragically passed away the following year at age 56 after a two-year battle with non-small-cell lung cancer. She is survived by her husband, Dennis Troper, and their four children, following the tragic loss of their son, Marco, who died at age 19 from an accidental overdose while attending UC Berkeley.
Susan’s Legacy at YouTube: During her tenure, YouTube grew into a global platform with over 2 billion users, revolutionizing online video content and creator culture.
The Wojcicki sisters’ story is a testament to the power of family, education, and a relentless pursuit of innovation. While Anne Wojcicki’s current battle for 23andMe remains uncertain, the legacy of these three remarkable women continues to inspire and shape the landscape of Silicon Valley and beyond.
