In my case, it is not completely full-time, but a decent portion of my time. The "trick" in my case is that I am an independent consultant, and open-source is how I dedicate some days of my workload (and a bit of weekends too, but only when I want it). I have published an open-source Ruby data processing framework in 2015 (https://www.kiba-etl.org https://www.kiba-etl.org). I sustain myself by two ways: 1/ consulting on either Kiba ETL (which brings leads) or other data projects and 2/ "Kiba Pro" commercial extensions providing more features with vendor support (yes, proprietary code, not OSS, on that specific part). I have explained in depth how and why I decided to go that route in a talk this year: https://www.youtube.com/watch?v=yv1EnYTXIeA https://www.youtube.com/watch?v=yv1EnYTXIeA About GitHub Sponsors: I'm giving it some thoughts, but some parts are blurry for me as a French company, lawyers have no answers yet, and GH support could not help me from a legal/fiscal standpoint here. I also do not expect much, but will likely try it out. Hope this helps, although this road is not for everyone!
