Jenny Fleiss is known for taking risks to make the everyday act of shopping a more enjoyable experience -- from her first lemonade stand as a kid to the massively successful Rent the Runway. Now, her new venture, JetBlack, aims to save people time through a personalized shopping experience that starts with a text -- and ends with the product being delivered to your door. It’s a new idea that Jenny hopes will help professionals like herself make the most out of their busy weeks.
