Susan Wojcicki’s career connects several chapters of internet history, from Google’s garage beginnings to the growth of online advertising and video. Her work offers a useful way to understand how a technology company develops products, earns revenue and takes on responsibility as it grows.

Who was Susan Wojcicki?

Susan Wojcicki was an American technology executive and YouTube’s CEO from 2014 to 2023. Before leading YouTube, she helped build Google’s marketing, search products and advertising business. She also helped make the case for Google’s acquisition of YouTube in 2006.

She died on August 9, 2024, at age 56, after living with lung cancer. Her career included advocacy for paid parental leave, women in technology and broader access to education. UC Santa Cruz’s remembrance describes her support for first-generation students alongside her work in technology.

Early life and education

Wojcicki was born in Santa Clara, California, in 1968 and grew up in the Stanford area. Her father, Stanley Wojcicki, was a Stanford physics professor, and her mother, Esther Wojcicki, was an educator.

She studied history and literature at Harvard before earning a master’s degree in applied economics at UC Santa Cruz in 1993 and a Master of Business Administration at UCLA Anderson in 1998. Her UCLA alma mater credits her with a lasting commitment to data analysis as a business decision-making skill.

At UC Santa Cruz, she met her future husband, Dennis Troper. The university later described her graduate training in mathematics, statistics and economics as a foundation for the analytical work she did throughout her career.

From Google’s garage to its advertising business

In 1998, Wojcicki rented space in her Menlo Park home’s garage to Larry Page and Sergey Brin. They were building Google. She joined the company in 1999 as its first marketing manager.

Her early assignment included finding ways for people to discover the search engine on a small budget. One approach was letting other websites embed Google search boxes on their pages. A Johns Hopkins profile recounts how this helped Google reach people without paying for traditional advertising.

Her responsibilities expanded well beyond marketing. She worked on Google Image Search, Google’s early video and book search products, and early parts of AdSense’s creation. AdSense, launched in 2003, let publishers earn money by displaying relevant advertising on their websites.

In her AdSense anniversary post, Wojcicki remembered the small team gathered in a conference room as the service went live. The product connected Google’s advertising business with independent publishers who needed a way to fund their content.

She later became Google’s senior vice president of Advertising and Commerce. Her advertising remit included AdWords, AdSense, DoubleClick and Google Analytics. These roles gave her experience across product development, distribution and the systems that turned online attention into revenue.

Her role in Google’s YouTube acquisition

Wojcicki was working on online video at Google when YouTube was growing. Google already had a video business, and YouTube brought an established brand and community.

In her YouTube retrospective, she described being struck by both sides of the audience behavior. People wanted to upload everyday moments, and other people wanted to watch them. She and fellow Google executive Salar Kamangar advocated bringing Google and YouTube together.

On October 9, 2006, Google announced an agreement to acquire YouTube for $1.65 billion in a stock-for-stock transaction. The acquisition announcement said YouTube would retain its brand and operate independently. Google would contribute technology, advertiser relationships and global reach.

Google was the buyer, with Wojcicki participating as an executive. She later took on a different responsibility as YouTube’s CEO in 2014.

For us as investors, the useful question is how a team compares its own product with an alternative customers already use. Our co-founder Elizabeth Yin writes in Democratizing Knowledge that decisions are “a comparison game.” In the same book, Yin writes, “The more disciplined you are in your thought process/rubric, the more you can improve over time.” We use those principles to examine the choices a team had at the time, even when we already know the outcome.

The YouTube years, 2014–2023

Wojcicki became YouTube’s third CEO in 2014, following Chad Hurley and Salar Kamangar. Her nine years in the role included new subscription businesses, more ways for creators to earn money and difficult decisions about the content YouTube distributed.

Building businesses around video

During her tenure, YouTube expanded beyond its advertising-supported video service with products including YouTube Music, Premium and YouTube TV. Creators also gained additional revenue options, including channel memberships, merchandise and Super Chat, which lets viewers pay to highlight messages during live chats.

Her 2019 creator letter described monetization as an ongoing pain point. Advertisers wanted confidence about where their ads appeared, while creators needed understandable decisions about which videos could earn advertising revenue and a way to appeal mistakes.

These were team efforts. In her departure note, Wojcicki credited chief product officer Neal Mohan and his teams with major roles in YouTube TV, Music, Premium and Shorts. Her leadership included building the organization that developed and ran those products.

Openness, moderation and privacy

YouTube’s growth also brought disputes about harmful content, hate speech, harassment and the treatment of children’s data. In 2019, Wojcicki set out her approach to responsibility, arguing for an open platform with rules to protect its community.

The problems had concrete consequences. That year, Google and YouTube agreed to pay $170 million to settle allegations by the Federal Trade Commission and New York’s attorney general. The FTC’s September announcement said regulators alleged that YouTube collected persistent identifiers, such as cookies, from viewers of child-directed channels to serve targeted ads without parental consent.

Her tenure includes both the expansion of a creator business and a major regulatory settlement over children’s privacy. Running YouTube required decisions that affected creators’ livelihoods, advertisers’ confidence and viewers’ safety.

Advocacy, departure and legacy

Wojcicki advocated for women in technology, paid parental leave and education. In his tribute to Wojcicki, Sundar Pichai described her efforts to improve parental leave and her support for educational creators, especially those extending science and technology education to underserved communities.

Her support for education also included scholarships for first-generation UC Santa Cruz students and an endowed chair in data science and innovation at UCLA Anderson. The American Advertising Federation inducted her into its Advertising Hall of Fame, recognizing a career that spanned Google’s advertising systems and YouTube’s video business.

In February 2023, she stepped down as YouTube’s CEO. Neal Mohan succeeded her. In her departure message, she said she wanted to focus on family, health and personal projects, and planned to take an advisory role across Google and Alphabet.

After her death, YouTube published her final post on November 25, 2024. Wojcicki had written it in the final weeks of her life. She explained that she had been diagnosed with lung cancer at the end of 2022 and described her support for research into earlier detection and new treatments.
