If you founded or work for a YC startup, I would love to know if your startup uses Errbit [1] or Fat Free CRM [2]. (Open-source Ruby on Rails applications.) If so, I would really appreciate it if you could leave a comment with the name of your startup, and the apps that you use. Thanks!

Full disclosure: I'm applying for an O-1 visa so that I can move to SF and work for a YC startup. I've contributed a lot of code to these apps, but need some statistics for a recommendation letter.

An H-1B visa would definitely be easier, but unfortunately, I don't have a degree or the required experience.
