“If I have to pick just one, I would strongly advise hiring more experienced people earlier. At McKinsey, we always had the saying, “Talent and experience for breakfast.” That might be absolutely true in consulting, but it’s absolutely not true in a startup. Specifically, not in a startup where you have to do things you have absolutely no clue about. Of course, you can try figuring it all out yourself, but you’re so much faster if you just hire a few people who know how to do that stuff.”
