I've been commissioned by a large company client to add Cyrillic to one of my more successful preexisting typefaces.
After completing that work, since they don't own exclusivity to this customization, I'll add it as an update to that family wherever my fonts are already being sold.
However, I think it could also be an opportunity to expand to other sites. I do vaguely remember I was once considering a site that was focused on selling Cyrillic or multilingual type but for the life of me can't find it now.
Do you have any recommendations for a reputable (and hopefully profitable) partner that would match this description?
