James Park’s heart rate and sleep patterns tell the real story of what it’s like to be the chief executive of a company about to go public. Park wore Fitbit’s (FIT) Surge “super­watch” during the entire process, from the company’s initial SEC filing through the subsequent road show and finally to his IPO-day celebration with a New York–style hot dog. Even Jim Cramer couldn’t get a rise out of him. Here’s a look at the numbers.


James Park’s Tips for Managing IPO Stress:

  • Stay focused on a specific goal. (Even if it’s a hot dog.)
  • Be prepared. “We had almost 100 meetings with investors.
  • Get a consistent amount of sleep every night. “Data is helpful to maintain discipline.”
  • Stay fit. “Health is an important part of managing the ups and downs of running a company.”
