The idea that it's better to just do something quickly and learn from mistakes, rather than take your time, get a lot of good advice, and do it right, seems very accepted but I think it is not always generalizable. In particular, in biotech the cost of a failed experiment is much higher and one poorly designed experiment can kill a company. It's best to get an advisory board with relevant yet diverse experiences to really dig through the details of the experimental design and critically think about what you do and don't know about the biology
I know a few biotech founders who have the tech startup mindset of just getting some money and rushing into an experiment, except they need $200k and 6 months for that experiment. If you realize three months in when it's too late to stop that one of your assumptions was wrong, or you used the wrong model, that's a terrible feeling
