The Lean In organization traces its origins back to the influential book written by its founder, Sheryl Sandberg, titled "Lean In: Women, Work, and the Will to Lead." Published in 2013, Sandberg's book ignited a global conversation on gender equality in the workplace and inspired women around the world to strive for leadership roles. Building upon the book's success, the Lean In organization was established with a clear mission in mind: to empower women and encourage them to pursue their ambitions. Today, Lean In continues to provide a supportive platform, offering resources, community, and mentorship to women seeking to overcome barriers, cultivate self-confidence, and achieve their professional goals. The organization's focus has expanded to address other key areas of gender inequality, including biases ingrained in policies and practices. With the core belief that when women lean in, they can change the world, Lean In remains committed to creating a more inclusive and equitable society for all.
