Ask HN: Most beautifully designed SaaS web app?

I know that a lot of people are urging to comment that good design is functional design, not "beautiful design"; and then go on about how a lot of "modern" websites are horrifically designed because they just aim at being aesthetically pleasing, not useful UI. I mostly do not disagree with the sentiment, but... I do want to find web apps that are beautiful. The reason is that I have a web app that I believe has a pretty good functional design, but it is relatively ugly. No customer is enchanted by it, making it harder to make them use it long enough to realize that the design is functional. I am no designer. I was only capable of making it functional because I use the app myself and I listen to customers that validate that my design is more practical than competitors. I am a solo founder, and I have no money to hire a good designer to make it beautiful and keep it functional. So I want some references to serve as inspiration so I can create a beautiful design myself. Thanks! :)
