What I learned this week:
Gumroad is a simple payment tool to sell products online - and while it's targeted primarily at artists and other creators, it's insanely easy to use and set up for most simple products online.
I learned recently that you can host videos on Gumroad itself, so in one day I was able to make a simple online course without any tools other than a simple landing page on something like Carrd.
If you're selling an e-book, an online course, a pack of images, a song, literally anything you can download, watch, or absorb online - you can sell it with Gumroad. And it takes less than an hour to set it up.
The potential there is mind-blowing to me. I spun up a course page in a day - spent an hour and a half filming, uploaded it to Gumroad, and I was done.
