Ms. Huffington, 66, announced her departure in a memo to staff of the publication, which was acquired by AOL for $315 million in 2011 and is now part of Verizon Communications Inc.'s media business. She said she had intended to keep running The Huffington Post but decided to turn her attention to her startup, Thrive Global, after attracting investors and hiring staff.
"There is only one way to do it: with your full attention and all your heart," Ms. Huffington said. "This is also the only way I have ever known how to run HuffPost through the years, as we have evolved and grown, taking the risks that have led us where we are today."
Verizon had given Huffington permission to pursue the new venture while staying with the company, where she serves as president and editor-in-chief of The Huffington Post, people familiar with the matter told Bloomberg News in June.
