One of the most influential women in Silicon Valley, Sandberg, 54, will depart the board as the tech juggernaut behind Facebook, WhatsApp and Instagram faces increased regulatory scrutiny. Sandberg said on Wednesday that she would not stand for re-election once her term ends in May, but would serve as an advisor to the company thereafter. "With a heart filled with gratitude and a mind filled with memories, I let the Meta board know that I will not stand for reelection this May," Sandberg posted on Facebook.
