I'm can't propose an equity split, but given those facts I think Eddie deserves more than Mark who deserves more than Fred. This will be a full time job for Eddie, a part time job for Mark, and a side project for Fred. (Yes, I'm sure Fred will work 100 hour weeks and that his day job is easy, but the mental tax of holding two jobs cannot be overstated.) But I wouldn't divvy up 100% right now. I would keep some equity unallocated so that if Mark or Fred decide to work for the startup full-time, their equity can be adjusted to reflect that.
