Nervous about joining an early stage startup? Let's talk about risk. There are two types of risk: job risk and career risk. People think they are the same. They aren't. They are very different.
If you notice something at your company below standards and don't fix it or make sure someone else does, you have set a new standard.
Complaining about it does not count as fixing it.
If someone gets upset/tells you to stay in your lane, they've set an even worse new standard.
