Origin & Impact

Facebook COO Sheryl Sandberg’s book “Lean In: Women, Work, and the Will to Lead” sparked conversations about women in leadership when it debuted in March 2013. The hashtag became shorthand for encouraging women to pursue ambition, negotiate, and take risks in their careers.

The movement sparked both enthusiasm and criticism. Supporters praised empowering individual action, while critics argued it placed too much burden on women to fix systemic inequality. LeanIn.org formed to support women’s circles worldwide. The phrase entered business vernacular, and the hashtag continues in discussions about women’s workplace advancement and corporate feminism.
