Marissa Ann Mayer (born May 30, 1975) is an American business executive, software engineer, and investor who became one of the most prominent figures in Silicon Valley during the first two decades of the twenty-first century. She joined Google in 1999 as the company's twentieth employee and its first woman software engineer, rising over thirteen years to become a vice president overseeing some of the search giant's most consequential products, including Google Search, Google Maps, and Google News. In July 2012, she was named president and chief executive officer of Yahoo!, a role she held until the company's core internet business was sold to Verizon Communications in 2017. Her appointment at Yahoo drew widespread attention both for her ambitious turnaround strategy and for the fact that she announced she was pregnant on the same day she accepted the position. After leaving Yahoo, Mayer co-founded the consumer technology startup Sunshine, which she later dissolved in 2025 before launching a new artificial intelligence venture called Dazzle AI. As of 2025, Mayer also serves on the boards of directors of Walmart, AT&T, Hilton Hotels & Resorts, and Starbucks.

Early Life

Marissa Ann Mayer was born on May 30, 1975, in Wausau, Wisconsin, a small city in the north-central part of the state. Details of her childhood and family background, as documented in published sources, indicate that she grew up in Wausau and attended local schools before pursuing higher education in California.

Mayer has spoken publicly about developing an early interest in mathematics and science. Her upbringing in a modest Midwestern city would later become a frequently noted biographical detail in media profiles that contrasted her small-town origins with her eventual rise to the upper echelons of Silicon Valley's technology industry.

Education

Mayer attended Stanford University in Stanford, California, where she earned a Bachelor of Science degree and a Master of Science degree, both in computer science. Stanford's computer science program, one of the most selective in the United States, placed Mayer in proximity to many of the individuals and ideas that would shape the early internet era. It was through her studies at Stanford that Mayer was exposed to the nascent search engine research being conducted by Larry Page and Sergey Brin, the co-founders of Google, which proved consequential for her subsequent career.

Career

Google (1999–2012)

Mayer joined Google in 1999 as the company's twentieth employee, making her the firm's first woman software engineer. Over the course of thirteen years at the company, she held a series of increasingly senior positions, eventually rising to vice president. During her tenure, Mayer led product development and user interface design for some of Google's flagship offerings, including Google Search, Google Images, Google News, Google Maps, and Gmail.

Mayer became a prominent public spokesperson for Google and was known within the company for her focus on usability and design. She was a proponent of data-driven decision-making in product design, applying rigorous testing methodologies—including extensive A/B testing—to refine the user experience of Google's core products. Her approach to simplicity in design was the subject of media coverage and industry discussion.

During her years at Google, Mayer also became one of the most visible women in the technology industry. She was a regular presence at industry conferences and was frequently cited in media coverage of Silicon Valley. Her role at Google established her reputation as both a technical expert and a business leader, positioning her for the CEO role that would follow.

In addition to her work at Google, Mayer was an active angel investor in technology startups during this period. Her investments included stakes in several early-stage consumer internet companies. She invested in companies such as One Kings Lane, an online home décor flash-sale site, and Brit + Co, a media and e-commerce platform.

Yahoo! CEO (2012–2017)

On July 16, 2012, Yahoo's board of directors appointed Mayer as the company's president and chief executive officer. The appointment was seen as a significant moment for the struggling internet pioneer, which had cycled through several CEOs in the years prior and was searching for a leader who could revitalize its business. On the same day her appointment was announced, Mayer revealed that she was pregnant with her first child, a disclosure that generated substantial media attention and public discussion about gender, leadership, and work-life balance in the technology sector.

Mayer gave birth to her son, Macallister, in September 2012, and returned to work shortly thereafter.

Workplace and Human Resources Policies

Upon taking charge at Yahoo, Mayer implemented a series of changes to the company's workplace culture and human resources practices. In February 2013, she issued a directive requiring all remote employees to report to Yahoo offices, effectively ending the company's work-from-home policy. The decision was controversial and prompted a public debate about the merits and drawbacks of remote work in the technology industry.

In April 2013, Mayer doubled the length of Yahoo's paid maternity leave and introduced eight weeks of paid paternity leave for new fathers, a move that was viewed as an effort to improve employee morale and attract talent.

Later in 2013, Yahoo introduced a quarterly performance review (QPR) system that ranked employees on a curve, a practice that drew criticism from some within the company. Employees expressed frustration with the system, which was seen as facilitating a process of quiet layoffs, as those ranked at the bottom of the curve faced potential termination.

Strategy and Acquisition

Mayer's strategy at Yahoo focused on revitalizing the company's core products, with a particular emphasis on mobile platforms. She spoke publicly about mobile as a top priority for the company, outlining her vision at industry events and conferences. She discussed the competitive landscape of the technology industry alongside other prominent executives, including Mark Zuckerberg, at events such as TechCrunch Disrupt.

Under Mayer's leadership, Yahoo embarked on an aggressive acquisition strategy, purchasing dozens of startups in an effort to bolster its talent base and product portfolio. The most significant of these acquisitions was the purchase of Tumblr, the blogging and social networking platform, in 2013 for approximately $1.1 billion. Mayer sought to use Tumblr's user base and mobile engagement to reinvigorate Yahoo's relevance among younger internet users.

Despite these efforts, Yahoo's core advertising business continued to face challenges from larger competitors, particularly Google and Facebook. The company's financial performance remained uneven, and Mayer faced recurring scrutiny from investors and analysts over the pace and effectiveness of her turnaround plan.

Mayer served as Yahoo's CEO until 2017, when the company's core internet operations were sold to Verizon Communications. The sale marked the effective end of Yahoo as an independent publicly traded company, though its remaining assets—primarily its stakes in Alibaba Group and Yahoo! Japan—continued as a separate entity later renamed Altaba.

Sunshine (2018–2025)

After departing Yahoo, Mayer co-founded Sunshine, a consumer technology startup, in 2018. The company focused on developing applications powered by artificial intelligence, including a contacts management application called Sunshine Contacts and a photo-sharing app. Sunshine operated as a small startup lab and experimented with various consumer-facing AI products.

However, the startup's products did not achieve significant consumer adoption. In September 2025, it was reported that Mayer was dissolving Sunshine and shutting down its operations. Business Insider noted that Sunshine's photo-sharing application "never really caught on" with users.

Dazzle AI (2025–present)

Following the closure of Sunshine, Mayer launched a new startup called Dazzle AI, focused on the emerging field of generative artificial intelligence and agentic AI. In December 2025, Dazzle raised $8 million in a seed funding round led by Forerunner Ventures' Kirsten Green. The company was described as developing consumer-facing AI products, with Mayer positioned as its founder and CEO.

TechCrunch reported that Mayer "refuses to sit on the sidelines of the generative AI revolution," noting that the venture represented her return to the startup world after spending several years working on Sunshine.

Board Memberships

In addition to her entrepreneurial activities, Mayer has served on the boards of directors of several major corporations. Prior to Yahoo, she joined the board of Walmart. As of 2025, she serves on the boards of Walmart, AT&T, and Hilton Hotels & Resorts.

In June 2025, Starbucks announced the election of Mayer to its board of directors, alongside economist Dambisa Moyo.

Personal Life

Mayer married Zachary Bogue, an investor and attorney, in December 2009 at a ceremony in San Francisco. The couple have three children together. Their first child, a son named Macallister, was born in September 2012, shortly after Mayer assumed the role of CEO at Yahoo.

Mayer's decision to publicly announce her pregnancy on the same day she was named Yahoo CEO generated significant media attention and became a focal point of broader conversations about women in executive leadership, maternity leave, and the intersection of career ambition and family life in the technology industry.

Recognition

Mayer has received numerous honors and accolades over the course of her career. In 2013, Fortune named her its Businessperson of the Year, recognizing her efforts to turn around Yahoo in her first year as CEO.

She has appeared multiple times on Fortune's annual list of the Most Powerful Women in business.

Her role at Google and subsequently as CEO of Yahoo made her one of the most frequently profiled women in the technology industry, and she was regularly featured in business and technology publications including Bloomberg Businessweek, The New York Times, Fast Company, and Fortune.

Legacy

Mayer's career spans a period of extraordinary transformation in the technology industry, from the early growth of Google into one of the world's largest companies to the decline and eventual sale of Yahoo, and into the era of generative artificial intelligence. As Google's first woman software engineer and its twentieth employee, she played a formative role during the company's most consequential years of growth, contributing to the design and development of products that came to define the modern internet experience.

Her tenure at Yahoo remains a subject of analysis and debate. While she implemented significant changes to the company's culture, products, and talent strategy—and oversaw a substantial rise in the company's stock price driven in part by the value of its stake in Alibaba—the core advertising business continued to struggle, and the eventual sale to Verizon marked the end of Yahoo as an independent company. Her leadership decisions, including the elimination of remote work and the introduction of stack-ranking performance reviews, generated both support and criticism and contributed to broader industry discussions about workplace management practices.

Mayer's simultaneous announcement of her pregnancy and CEO appointment in 2012 became a cultural milestone, sparking national conversations about gender in executive leadership and the expectations placed on women in positions of corporate power. Her subsequent expansion of Yahoo's parental leave policies added a tangible policy dimension to these discussions.

Her continued engagement with the technology industry through board service at companies such as Walmart, AT&T, Hilton, and Starbucks, as well as her entrepreneurial ventures with Sunshine and Dazzle AI, reflects an ongoing role in shaping how consumer technology products are developed and brought to market.
