While it’s no secret that hiring a personal assistant can help founders and executives save time, few know how to truly do it well. On one hand, early-stage companies try to conserve financial resources — and oftentimes executives’ valuable time is spent on tasks that they don’t need to do themselves, leading to talent shortages in small teams. On the other, executives at larger organizations have the resources to hire assistants but don’t know how to set up a partnership that optimizes their time and makes their assistants’ talents go the extra mile.

Over the last 24 years, I’ve hired a dozen different assistants, many of whom have been pivotal to my company’s growth and success, and who have helped me save well over 10 hours every week. Several others, however, taught me important lessons that I keep in mind whenever I look to hire a new assistant to support my team’s executives.
