Sandberg lays out LeanIn's next big challenge

It's been nearly a year since Facebook Chief Operating Officer Sheryl Sandberg published "Lean In" and launched a movement, with a non-profit and "Lean In" circles to help women pursue their goals. At the inaugural "Makers Conference," which is focused on women leaders, Sandberg sat down for an exclusive interview to talk about what has accomplished and how much more it needs to do.

The biggest challenge, Sandberg said, lies ahead. Achieving equality requires that companies understand the barriers women face, and acknowledge that achieving equality is necessary not just to help women, but to help business.

"I think what we're seeing is that CEOs (and most of them are men, some are women), are recognizing that this isn't something that makes them feel good. This isn't about equality for women. This is about their bottom line," Sandberg said. "That if they can embrace and use the full talents of the population, their companies can outperform. And I think that leads to the change we need to see."
