Thanks for your comment. I guess you should look into outsourcing / hiring / automating some of the more mundane tasks. Though for the second group of tasks you outlined, having a founder specialize in them, so that the other founders can focuse on the technical side, sounds like a good thing.

And it allows the business guy to grow. Eventually you will want to have a business guy anyway, so it's a sound approach to train him from day 0.
