Early Life & Education
Anne Wojcicki was born in San Mateo, California, in 1973, the youngest of three daughters of Esther Wojcicki, an educator, and Stanley Wojcicki, a physics professor at Stanford. She grew up in a household that placed enormous value on intellectual curiosity and scientific rigour — her sister Susan would go on to become CEO of YouTube, and her sister Janet is an epidemiologist at UCSF. Anne studied biology at Yale, where she developed an interest in the intersection of genetics and human health. After graduating, she spent several years as a healthcare investment analyst on Wall Street, developing a deep understanding of the pharmaceutical and biotechnology industries before deciding to build a company of her own.
Founding 23andMe
Wojcicki co-founded 23andMe in 2006 with Linda Avey and Paul Cusenza, with the mission of making personal genetic information accessible and useful to ordinary people. The company's name refers to the 23 pairs of chromosomes in a human cell. The initial product — a saliva-based DNA test that provided customers with information about their ancestry and genetic health risks — was a genuine innovation in consumer health. Google co-founder Sergey Brin, who was then married to Wojcicki, was among the company's early investors. The company grew rapidly, driven by consumer curiosity about ancestry and genetic traits, and at its peak had genotyped more than 14 million customers.
Regulatory Battles and Pivots
23andMe's path was never smooth. In 2013, the FDA ordered the company to stop marketing its health-related genetic tests, ruling that they constituted medical devices that required regulatory approval. The company spent several years working through the regulatory process before receiving FDA authorisation for specific health risk reports in 2017. The episode forced a significant rethinking of the company's strategy and delayed its ambitions in health-related genomics by years. It also demonstrated the complexity of operating at the intersection of consumer technology and regulated healthcare — a tension that would continue to define the company's challenges.
Near-Collapse and Restructuring
23andMe went public via SPAC merger in 2021 at a valuation of approximately $3.5 billion. The years that followed were deeply difficult. A major data breach in 2023 compromised the genetic data of nearly 7 million customers, triggering regulatory investigations and class-action lawsuits. The company's consumer business slowed sharply as the initial wave of curiosity-driven purchases was not replaced by repeat customers. The board of directors resigned en masse in 2024. Wojcicki took the company private in 2025, buying it out of bankruptcy proceedings and retaining control of the genomic database she had spent nearly two decades building.
The Drug Discovery Bet
The asset Wojcicki has fought to preserve through all of this is the genomic database — millions of consented research participants whose genetic data, linked to health outcomes, represents an extraordinary resource for drug discovery. 23andMe's therapeutics division has active programmes in oncology and immunology, using the database to identify genetic variants associated with disease and to find patient populations for clinical trials. Whether this bet will ultimately pay off remains to be seen. But Wojcicki's conviction — that the data asset she built is genuinely transformative for medicine — has not wavered, even through the most difficult years of the company's history.
"We built the largest consented genomic database in the world. The question now is whether we can turn that asset into medicines that actually help people."
Anne Wojcicki co-founded 23andMe in 2006 with the conviction that giving people access to their own genetic data would transform how they understood and managed their health. The company she built became a cultural phenomenon — and then a cautionary tale about the gap between consumer enthusiasm and sustainable business models. We spoke with Wojcicki about what went wrong, what she learned, and why she believes the company's most important chapter may still be ahead of it.
23andMe went through an extraordinarily difficult period — the data breach, the financial struggles, the board resignations. What did you learn from that?
I learned that building a consumer business and building a drug discovery business are two fundamentally different things, and that trying to do both simultaneously with the same capital base is very hard. The consumer business — selling DNA kits — is a one-time purchase. People buy it once, they get their results, and they move on. That is not a recurring revenue model. The drug discovery business is a long-cycle, capital-intensive endeavour that requires a completely different kind of investor patience. We tried to fund the second with the cash flows from the first, and when the consumer business slowed, the whole structure came under pressure.
The data breach was a significant moment — genetic data for millions of customers was compromised. How do you think about the responsibility that comes with holding that kind of data?
It is the most serious responsibility I have ever had. Genetic data is not like a credit card number that you can cancel and replace. It is permanent, it is deeply personal, and it has implications not just for the individual but for their family members. The breach was a failure, and I take full responsibility for it. What I can say is that we have invested significantly in our security infrastructure since then, and that the consent framework we built — where customers explicitly choose what their data can be used for — remains one of the most rigorous in the industry.
What is the core thesis of 23andMe now, after everything that has happened?
The thesis has not changed. We built the largest consented genomic database in the world — millions of people who have agreed to have their genetic data used for research. That is an extraordinary asset. No pharmaceutical company has anything like it. The question now is whether we can turn that asset into medicines that actually help people. We have drug discovery programmes in oncology and immunology that are using that data in ways that would not be possible without it. That is the bet. It is a long bet, but I believe in it.
The consumer genomics market has not grown the way many people expected. Why do you think that is?
The initial wave of adoption was driven by curiosity — people wanted to know their ancestry, their genetic traits. That is a finite market. The next wave of adoption has to be driven by genuine health utility — people using their genetic information to make better decisions about their health, to understand their disease risks, to work with their doctors in a more informed way. That transition has been slower than I hoped, partly because the healthcare system has not yet built the infrastructure to act on genetic information at scale, and partly because the regulatory environment for genetic health information is complex. But I think it is coming.
If you were starting 23andMe today, what would you do differently?
I would separate the consumer business and the drug discovery business from the beginning — different capital structures, different investor bases, different management teams. The consumer business is a marketing and distribution challenge. The drug discovery business is a science and clinical development challenge. They require completely different skills, and trying to run them as one company created confusion about what we were and what we were trying to achieve. The data asset that connects them is real and valuable. But the businesses built on top of it should probably be distinct.
