How different does your product have to be?

Often founders are trying to rack their brains for the next super unique idea - and are often demoralised when they find out it exists elsewhere. How important is it to be the only player in the market? Would love to hear everyone’s thoughts. We’re a platform with one of our core features existing elsewhere offered by a decently popular competitior. However, we have a tonne of features targeted specifically for Enterprise that they don’t have. I’d love to know what people think, and how they approached standing out in a competitive space :)
