Do DAOs make money?

Could you please elaborate on whether DAOs actually generate revenue? I'm curious to understand how these decentralized autonomous organizations manage to turn a profit, if they do at all. Do they rely on specific business models or income streams? And how does this revenue generation process work in the context of blockchain technology and cryptocurrency? I'm also interested in knowing if there are any challenges or limitations in this regard that DAOs might face. Could you provide some insights into this matter?
