Awesome. Are you open to sharing some #'s? How many people sponsored this?
I'm up to 211 sponsors, about $1700 per month.
Many of those sponsors are one-time donations. At the beginning, I set the minimum one-time donation to $1; once I reached 100 sponsors, I bumped the minimum up to $10.
The larger sponsors come mostly from digital ink library perfect-freehand (https://github.com/steveruizok/perfect-freehand), also MIT licensed, which is being used by many products such as Next.js live, Milanote, Clover, etc.
