Former Zappos CEO Tony Hsieh has died at the age of 46 from injuries he sustained from a house fire. Hsieh “catapulted the shoe company into the big leagues with a sale to Amazon and then used the proceeds of his success in a huge project kickstarting regeneration of a run-down part of Las Vegas with tech and wider business investments,” according to TechCrunch. “Hsieh was a brilliant, offbeat, and — to many people, often very directly — kind-hearted person who was regularly described as a visionary.”
