This raises the question of whether you need a co-founder or a hire. It depends on the business.

IMO "40% is way too high for a designer" is too general. It depends on how significant a part of the leadership team they're going to be. Since you say you want them to "help out on the front end" - I'd lean towards guessing that you might need a hire, not a co-founder.

Also a good point. I wasn't too specific but I was thinking more someone with previous startup experience and also at least a little bit business savvy.
