(And glad to hear that conference sponsorships work. A lot of smaller conferences are struggling to find sponsors these days, so if anyone reading is in a position to sponsor, the organizer of your favorite conference would probably appreciate it!)
FWIW, first time I saw you was at LonghornPHP in Austin. 2021, IIRC.
The organizer of Longhorn PHP is a friend of ours (Daniel Abernathy), and we have a somewhat official-unofficial rule that we always sponsor our friends' conferences :)
