Notably, shattering the glass ceilings, she became the first woman on Facebook's board of directors in 2012. Beyond her professional achievements, Sandberg's personal life reflects her love for innovation and investment. In 2009, she acquired a property in Menlo Park, California, for $2.9 million. Collaborating with her late husband, the property underwent an ambitious renovation, blossoming into a 9,210-square-foot masterpiece valued at $11 million. Its number of amenities, including a wine room, gym, movie theater, and solar panel-adorned green roof, mirror Sandberg's penchant for design and forward-thinking.
