Every company is different. Generally, in a smaller high-performance startup/company, you will tend to work more closely with everyone, but that does not mean there is no place for code reviews. In fact, in a smaller team, the bus factor[1] is so high that you need to ensure that there is good code ownership.

I didn't mean there's no place. I meant in my experience code reviews could me less polite. You can say straightforward whatever you think about the code.
