That's the thing, the only time I feel like founders should get a different distribution of equity is if one of the founders is paying salaries, paying for hosting, paying for business cards &c... That's how we are doing it at my company - my cofounder had the money and wanted to bootstrap, I was okay with that (I figure my cut will be worth more if we bootstrap instead of go 50/50 and find VC) so my cofounder is paying for everything including a "median" salary for me; we've done our split 20/80. As far as the other vectors go, I feel like they shouldn't matter - all the cofounders have a role and everyone should be working equally hard!! My test of the app assuming none of the cofounders were paying for everything put the split (for two of us) at 58/42. Which is silly because my cofounder may be the reason why we have customers and is also a key player in the industry - but there would be no app, no features, and it wouldn't be working as well as it would if an outsourced rent a coder had done the work.
