Hiring a new employee comes with risks. The right hire can drive your company forward to greater success. Invest in the wrong person, however, and you can cause real damage to company culture and productivity. Startup CEOs, in particular, should be wary of making common hiring mistakes.

1. Hiring constantly. A common misstep made by startup entrepreneurs is hiring too often or hiring for a quick fix. Not only will you waste time as you assess candidates, but you also risk wasting money on rash hiring decisions.

2. Hiring someone because you know them. When you hire friends or family members, you set yourself up for a few potential problems. Will that person expect special treatment? If the person doesn’t perform well, will you be able to give honest criticism—or will you lower your standards as you avoid speaking to the person? If needed, can you fire that person—and still remain friends?
