Katrina Lake (born December 24, 1982) is an American businesswoman and entrepreneur who founded Stitch Fix, an online personal styling and fashion subscription service that uses a combination of data science and human stylists to deliver personalized clothing selections to customers. Lake established Stitch Fix in 2011 while attending Harvard Business School, and grew it into a company generating over $1 billion in annual revenues. In November 2017, she took the company public on the NASDAQ stock exchange, becoming the youngest woman to lead an initial public offering in the United States at age 34. She was also the only woman in 2017 to lead an IPO of a technology company. Following the stock's early surge, Forbes named Lake one of America's richest self-made women. Lake served as CEO of Stitch Fix from its founding until August 2021, when she transitioned to the role of executive chairperson. She returned as interim CEO in January 2023 and has continued to serve in leadership roles at the company.

Early Life

Katrina Lake was born on December 24, 1982, in San Francisco, California. She grew up in the San Francisco Bay Area, an environment that would later inform her interest in both technology and entrepreneurship. Lake is of Japanese-American and European-American descent.

Lake developed an early interest in retail and the consumer experience. In a 2019 interview with NPR, she described how her entrepreneurial instincts emerged from a desire to solve a personal problem — the frustration many people experienced while shopping for clothing. In 2010, while considering the concept that would become Stitch Fix, Lake recruited 20 friends for an experiment to test whether she could select clothes for them that accurately matched their individual styles and preferences. This informal trial served as an early proof of concept for the personalized styling model that Stitch Fix would later adopt at scale.

Lake's upbringing in San Francisco, a city at the intersection of the technology industry and diverse cultural influences, provided her with a perspective that combined an appreciation for data-driven approaches with an understanding of the deeply personal nature of fashion and self-expression. Her background in the Bay Area also gave her proximity to the venture capital ecosystem and the startup culture that would prove essential in the early stages of building Stitch Fix.

Education

Katrina Lake attended Stanford University for her undergraduate education. After completing her studies at Stanford, Lake pursued a Master of Business Administration (MBA) at Harvard Business School.

It was during her time at Harvard Business School that Lake began developing the concept that would become Stitch Fix. She worked on the business model while still a student, exploring the idea of combining data analytics with personal styling to create a new form of retail experience. The academic environment at Harvard provided her with resources, mentorship, and connections that supported the early development of the venture. Lake launched Stitch Fix in 2011, shortly before completing her MBA.

Career

Founding of Stitch Fix

Katrina Lake founded Stitch Fix in 2011 in San Francisco. The company's premise was based on a hybrid model that combined algorithmic data analysis with the expertise of human stylists to curate personalized selections of clothing and accessories for individual customers. Customers would fill out detailed style profiles, and the company would use this data — along with machine learning algorithms — to select five items to ship to each customer in a "Fix." Customers could keep what they liked and return the rest.

The idea originated from Lake's 2010 experiment in which she personally selected clothing for 20 friends to test whether personalized curation could work as a service. Convinced the model had potential, Lake began building out the infrastructure for the business. The early days of Stitch Fix were characterized by a hands-on approach; Lake was personally involved in styling, logistics, and customer service during the company's formative period.

Building the company presented significant challenges, particularly in fundraising. Lake faced difficulty securing venture capital investment in the early stages. As she later recounted, the fundraising landscape for female founders was notably more difficult than for their male counterparts. In a 2018 interview with Forbes, Lake discussed how she navigated these challenges, turning a funding shortfall into what she described as one of her most important business advantages — the constraint forced the company to operate efficiently and become profitable earlier than many technology startups.

Growth and Expansion

Under Lake's leadership as CEO, Stitch Fix grew from a small startup into a major player in online retail. The company distinguished itself by investing heavily in data science, employing a team of data scientists alongside its team of human stylists. This combination of technology and human judgment became a central part of the company's identity and competitive advantage.

Lake positioned Stitch Fix at the intersection of fashion and technology, arguing that the two fields were more complementary than they were often perceived to be. In a 2018 interview with Digiday, she stated that "the current shift in customer behavior is permanent," expressing her view that consumers were increasingly comfortable with algorithmically-assisted shopping and that the trend toward personalized e-commerce would continue to accelerate.

The company expanded its offerings over time, moving beyond women's clothing to include men's clothing, plus-size options, and children's clothing. This broadening of the customer base helped drive revenue growth and expand Stitch Fix's market reach. The company grew to generate over $1 billion in annual revenues.

Initial Public Offering

On November 17, 2017, Stitch Fix went public on the NASDAQ stock exchange under the ticker symbol SFIX. The IPO represented a historic milestone: at 34 years old, Lake became the youngest woman ever to take a company public in the United States. She was also the only woman in 2017 to lead an initial public offering of a technology company, a fact that drew attention to the persistent gender disparity in the technology sector's leadership ranks.

In a 2018 interview with Digiday, Lake reflected on the IPO process, noting that the company "hadn't raised money in a long time" prior to going public, which meant that the IPO pitch required adjustment after a period of operating without significant external fundraising.

As of November 2017, Lake held a 16.6% stake in Stitch Fix. Following the stock's strong early performance, the value of her stake contributed to her inclusion on Forbes' list of America's richest self-made women in 2017.

Lake's record as the youngest woman to lead a company through an IPO stood until 2021, when Whitney Wolfe Herd took Bumble Inc. public at age 31.

Navigating the Public Markets

Lake's first year leading Stitch Fix as a public company brought new challenges and increased scrutiny. In her 2018 Forbes interview, she discussed the experience of managing a public company, including the demands of quarterly earnings reports, investor relations, and the increased visibility that came with being a publicly traded company's CEO.

During this period, Lake spoke publicly about the broader significance of a data-driven retail company being led by a woman in the technology sector. She addressed topics including the challenges faced by female founders in raising capital and the importance of representation in technology leadership. These discussions were covered in profiles and interviews across major publications including The New York Times, CNN, Elle, and Vogue.

Lake also discussed her management philosophy and approach to work-life balance in various interviews. In a 2019 profile in The Cut, she detailed her daily routine as the CEO of a public company, describing the practical logistics of leading a billion-dollar business while managing her personal life.

Transition to Executive Chairperson

In April 2021, Stitch Fix announced that Lake would transition from her role as CEO to become Executive Chairperson of the company's board of directors, effective August 1, 2021. Elizabeth Spaulding, who had been serving as President of Stitch Fix, was named as the new Chief Executive Officer.

The transition was framed as a planned succession, with Lake continuing to play an active role in the company's strategic direction as executive chairperson. The announcement noted that Lake would remain deeply involved in the long-term vision for Stitch Fix while Spaulding would handle day-to-day operational leadership.

Return as Interim CEO

Approximately 17 months after stepping down as CEO, Lake returned to the role on an interim basis in January 2023. TechCrunch reported that Lake resumed her position as CEO at a time when Stitch Fix was facing significant business challenges, including declining revenues and a falling stock price.

The return underscored Lake's continued centrality to the company she had founded. As the person most closely associated with Stitch Fix's brand and business model, her resumption of the CEO role was seen as an effort to stabilize the company during a difficult period and to chart a path forward.

As of early 2026, Lake continued to serve in a leadership capacity at Stitch Fix. A January 2026 SEC filing indicated that Lake, in her capacity as a director of Stitch Fix, sold 101,150 shares of Class A Common Stock for a total of $513,821.

Personal Life

Katrina Lake has two children. She has been based in the San Francisco Bay Area, where Stitch Fix is headquartered.

Lake has spoken publicly about the challenges of balancing the demands of leading a fast-growing technology company with her personal life. In her 2019 interview with The Cut, she described the practical realities of her schedule, offering a candid account of how she managed her time as a CEO and mother. She has also discussed the broader topic of working mothers in the technology industry in various media appearances.

Lake has used her platform to advocate for greater representation of women in technology and business leadership. Her status as one of the few women to lead a technology company through an IPO made her a prominent figure in conversations about gender equity in Silicon Valley and the broader business world.

Recognition

Katrina Lake has received significant recognition for her work in building Stitch Fix. In 2017, following the company's IPO and subsequent stock price surge, Forbes named Lake one of America's richest self-made women.

Lake was included in Fortune magazine's annual "40 Under 40" list, which recognizes influential young leaders in business. She was also recognized by the Business of Fashion as part of its BoF 500, a professional index of the people shaping the global fashion industry.

Her profile has been featured in numerous major publications, including The New York Times, Forbes, CNN, NPR, Elle, Vogue, Marie Claire, Fast Company, and Inc. magazine, among others.

Lake's achievement in becoming the youngest woman to take a company public in the United States at age 34, and the only woman to lead a technology IPO in 2017, received substantial media coverage and positioned her as a notable figure in discussions about gender representation in the technology and business sectors. Her record stood until 2021, when Whitney Wolfe Herd took Bumble public at age 31.

In 2018, Marie Claire profiled Lake as part of its coverage of female leaders of billion-dollar companies, highlighting the rarity of women leading companies of that scale in the technology industry.

Legacy

Katrina Lake's founding and leadership of Stitch Fix represented a significant development at the intersection of technology, retail, and fashion. The company's model — combining data science with human curation — offered an alternative to traditional retail and pure algorithmic recommendation systems, creating a category that influenced subsequent approaches to personalized commerce.

Lake's experience as a female founder navigating the venture capital landscape brought attention to the structural challenges faced by women in the technology industry. Her success in building Stitch Fix into a publicly traded company generating over $1 billion in annual revenues provided a counterpoint to the statistical underrepresentation of women in technology leadership. At the time of Stitch Fix's IPO in 2017, the proportion of venture capital funding going to female-led startups remained in the single digits, making Lake's achievement notable within this context.

The company's investment in data science as a core component of a fashion business also influenced how the industry thought about the role of technology in retail. Lake's public advocacy for the integration of algorithms and human expertise helped normalize the use of data-driven personalization in consumer-facing industries beyond pure technology platforms.

Lake's career trajectory — from a Harvard Business School student testing a concept with 20 friends to the CEO of a publicly traded company — has been cited in media coverage as an example of how consumer-facing innovation can emerge from identifying unmet needs in everyday experiences.
