# Sheryl Sandberg **Sheryl Sandberg** (b. 1969) is an American technology executive who served as Chief Operating Officer of [[Facebook]] (later [[Meta]]) from 2008 to 2022, building the advertising infrastructure that made the platform one of the most profitable companies in history. Author of the bestselling *Lean In* (2013), she was for years the most prominent woman in [[Silicon Valley]]. She appears in the KB primarily in connection with [[Facebook]]'s role in the [[Disinformation]] and data-harvesting crises of the 2010s and the political consequences of the ad-driven business model she scaled. ## Career Before Facebook Sandberg served as chief of staff to Treasury Secretary Larry Summers during the Clinton administration, then spent six years at [[Google]] as Vice President of Global Online Sales and Operations. Her move to [[Facebook]] in 2008 was transformative for both parties: she brought the operational discipline and advertising expertise that turned a college social network into a global revenue machine. ## Building the Ad Machine Sandberg's central contribution to [[Facebook]] was systematizing its advertising business around granular user-data targeting. Under her leadership, the platform developed the capacity to micro-target ads based on user behavior, interests, demographics, and social connections — the architecture that Shoshana Zuboff would later theorize as [[Surveillance Capitalism]]. The model was enormously profitable: Facebook's annual revenue grew from roughly $270 million in 2008 to over $117 billion by the time Sandberg departed. The same targeting infrastructure that served commercial advertisers also served political campaigns and, eventually, state-sponsored information operations. This was not an unintended side effect — political advertising was a revenue stream [[Facebook]] actively cultivated. ## Cambridge Analytica and the 2016 Crisis The [[Cambridge Analytica]] scandal revealed that the British consulting firm had harvested personal data from up to 87 million Facebook users without consent, exploiting the platform's permissive data-sharing policies. [[Cambridge Analytica]] used the data to build psychographic profiles for political targeting, including work for the [[Donald Trump]] 2016 presidential campaign. Internal reporting later revealed that [[Facebook]] had known about the data misuse for roughly two and a half years before it became public. Sandberg acknowledged the failure publicly — "We made mistakes and I own them. They are on me" — but critics argued the admission understated the degree to which the platform's business model itself was the problem. The company had optimized for engagement and data extraction; Cambridge Analytica was a feature, not a bug. Sandberg was also implicated in Facebook's broader handling of the 2016 election aftermath. Reporting by the New York Times described how she and [[Mark Zuckerberg]] initially resisted internal findings about Russian use of the platform to spread [[Disinformation]] and inflame social divisions, then worked to deflect scrutiny onto competitors rather than accept institutional responsibility. The [[Internet Research Agency]]'s operations on Facebook reached an estimated 126 million Americans. ## Post-Meta and Legal Exposure Sandberg stepped down as COO in 2022. In January 2025, a Delaware judge sanctioned her for allegedly deleting emails related to the [[Cambridge Analytica]] privacy litigation — a finding that, if upheld, would suggest ongoing efforts to obstruct accountability even after departure. She remains on [[Meta]]'s board and has shifted her public profile toward philanthropy and advocacy on gender and family issues. Her husband Dave Goldberg, CEO of SurveyMonkey, died suddenly in 2015; she later married Tom Bernthal in 2022. ## The Ad-Model Feedback Loop The business model Sandberg built at [[Facebook]] created a structural incentive to maximize engagement regardless of content quality. The algorithm rewarded emotionally provocative content — outrage, fear, tribal identity — because it kept users on the platform longer, generating more ad impressions. This dynamic made [[Facebook]] a force multiplier for [[Disinformation]], conspiracy theories, and political polarization. The same targeting tools that allowed advertisers to reach "women aged 25–34 who like yoga" also allowed bad actors to reach "users susceptible to anti-vaccine messaging" or "swing-state voters with ethno-nationalist leanings." The architecture was content-neutral by design and destructive by consequence. ## KB Significance Sandberg sits at the intersection of several KB threads. The advertising machine she built at [[Facebook]] is the infrastructure through which [[Disinformation]], political micro-targeting, and [[Surveillance Capitalism]] operated at scale. Her career illustrates how [[Big Tech]] leadership simultaneously built the tools that destabilized democratic information environments and resisted accountability for their consequences. The [[Cambridge Analytica]] scandal connects to the broader ecosystem of data exploitation, election interference, and the [[Section 230]] debate over platform liability. She also represents the [[Silicon Valley]] pattern of techno-utopianism masking extractive business models — the gap between *Lean In* feminism and the surveillance apparatus that made it financially possible. ## See Also - [[Facebook]] - [[Meta]] - [[Cambridge Analytica]] - [[Mark Zuckerberg]] - [[Surveillance Capitalism]] - [[Big Tech]] - [[Disinformation]] - [[Section 230]] - [[Internet Research Agency]] - [[Silicon Valley]] - [[Tech Oligarchy]]
