Good Morning everyone o/
Yeah, I think a founder of a project does need a business competence, cause when everything is going well its a bull its easy, but when the bear market hit and money starts to become short that's when a management of a business comes into play.
Yes, generally when everything is going up, the project moves forward smoothly, but, if you are a good leader with vision and financial knowledge, I am sure you will withstand a bear run, but you must know how to guide difficult decisions.
Competencies should not be seen as enemies, but as an opportunity to develop better strategies and growth. As you say, when everything is going well, it looks easy and you don't grow.
That's right, the leader or founder must be competent, have the skills to manage all aspects of the project and, of course, know how to work with his people, this is indispensable.
