If your business inquiry is about wanting advice for YouTube or a startup idea or if you want to get me involved in what you're doing or want to collab on some videos I would direct you here.
If this is for a speaking engagement or appearance or brand work or anything like that you should reach out to WME. They're great, I've been working with them for years.
If you want to hire me to make an ad campaign or something like that you can send an email to my office at werk (@) caseyneistat (dot) com. An intern monitors that address and only official business inquiries get a response.
thank you very much.
