For years, Rachel was paid to eat and drink as a food editor at places like O, the Oprah Magazine (dream!). But besides the copious amounts of chocolate and cheese, her favorite part of the job was talking with up-and-coming food entrepreneurs. Their stories led to “Cooking Up a Business” (Penguin, 2013), an insider guide to the world of food startups. As she wrote the book, Rachel picked up the entrepreneurial itch (it’s contagious!). She left her formal food editor career to launch guesterly, a software platform where anyone can create a who's who guide to their event. guesterly got such big buzz that Rachel then co-founded PR School, where entrepreneurs learn directly from editors how to get the word out about their brand and expertise.
