As a young professional with a hectic schedule, Audrey Gelman relied on coffee shops and Amtrak bathrooms to change clothes between commitments. It was this experience—and her desire for a more professional alternative—that first inspired the Wing, a female-focused, members-only club that she founded by opening a single co-working space in 2016. Since then, the Wing has taken flight; it now touts more than 10,000 members across nine locations, with new spaces set to open in 2020. —Mahita Gajanan
