This week we’re featuring an interview with John Rood, who built Next Step, a test prep business that helped students prepare for the medical school admissions test (MCAT). John Rood built Next Step to almost $10 million in revenue, with EBITDA margins ranging from 20–40% before selling to New Harbour Group, a private equity business doing a roll-up of test prep companies.   Although it was a financial windfall for John, his exit left him feeling empty inside. John drifted and ended up having a difficult time processing his newfound life, which led him to consider if other founders struggled with life post-exit. He began interviewing other entrepreneurs who had sold and is now putting the finishing touches on a book called Beyond the Exit, which will come out later this year.
