How do you take your product-ready startup from stage 0 to something everyone is talking about?

I have built plenty of amazing products, some of which are public on my GitHub (https://github.com/afrotechboss). But I always find it difficult to scale from there. I enjoy the building process, sometimes I even onboard a couple of first users, they love it, but after a while it dies off. I feel like I have a lot to learn. Any advice?
