I've been using Teachify for a while now and it works great for me.
I've been able to use my branding on the platform and I've created some courses and digital downloads - have a look: https://connectinglife.myteachify.com/
It's working really well. My clients are happy with the ease of use to go through a course or get a digital download. The payments are also going really well, so overall it's a really good tool.
I recommend it.
