A perfect logo still doesn't deliver any value to users. Marketing is a revenue multiplier, not a value multiplier. Design can increase value (e.g. UX/UI) but branding is all about revenue, not value. And, in open source, revenue is zero. Anything multiplied by zero is still zero. So, any strategy on the good use of capital (time and resources) would point to investments in the product not in marketing. The entrepreneurs you are seeing are just terrible capital allocators.

PS: we also don't have a website yet. :)
