Arianna Huffington is a serial entrepreneur who co-founded the Huffington Post in 2005 and founded Thrive Global in 2016. She advocates for redefining success to include well-being. Some of her ideas include providing nap rooms for employees and encouraging separating work from vacation. While the Huffington Post was highly successful, some of her other initiatives like HuffPost Live failed due to lack of audience. However, Thrive Global has grown significantly since its inception with multiple funding rounds.
