Entrepreneurship between couples and families is an interesting concept.

The pros: you have a strong relationship, know each other well and likely have similar values. The cons: it can be very difficult to separate business from pleasure.

Jason Feifer and Jennifer Miller know about this concept, as they’ve spent the last two years writing and producing their new novel “Mr. Nice Guy”. I sat down with them (in their home!) to talk about the book, and how to make it work as a marriage and business partnership.

Jason Feifer is editor-in-chief of Entrepreneur magazine, and host of two podcasts: Pessimists Archive (iTunes, site), about the history of unfounded fears of innovation, and Problem Solvers (iTunes, site), about how entrepreneurs solve unexpected problems in their business. He also co-wrote the new novel, “Mr. Nice Guy”.

Jennifer Miller is the author of four books, most recently “Mr. Nice Guy.” Her journalism appears in the New York Times, Washington Post Magazine, Bloomberg Businessweek, Entrepreneur, Fast Company and more. She also teaches at Columbia University.
