As a founder, what was your biggest challenge/pain while designing the UX of a product?

UX for a product is challenging and the number one difficulty I have noticed is how many decisions must be taken on the spot, without time to do research and reflect. Btw my company just launched a very cool AI tool: Xence by Gaspar AI

my biggest challenge while designing the UX of a product was balancing simplicity and intuitiveness with complex feature requirements, maintaining user engagement and satisfaction without compromising the product's core functionality and goals.
