I started using Gumroad just to start my digital journey of selling products. Started with few small projects but that didn't go well.
But then i understood the need and started creating 100+ Mesh gradient pack and it gained over 500+ downloads and 35$+ in revenue. I know its not too big but its a good start.
Here is the link if you wanna grab them for free : https://beingmani.gumroad.com/l/Meshgradient
