You need to think about how to manage expectations and ability of employees, particularly if they are the only person who does that job. You might take someone on who says they will do something and they don't, or they don't very well. How will you deal with that? What is a fair way of measuring someone's effectiveness. It is easy to try and be kind but if you e.g. have a salesperson who is not selling, they need to go. It is tempting to think you can't afford great people early on but plenty of businesses prove that great people sometimes put belief in the product or an interesting job/challenge or potential equity above a base salary.
