I think the Business Co-Founder getting a loan is a fantastic idea, and I've suggested it many times. Basically, each co-founder needs skin in the game, not one -- both. The technical co-founder is contributing $70k to 100k of time assuming 3mo of effort -- they are also "borrowing"...from an uncertain future. They have obvious skin in the game. The business co-founder needs equal skin in the game. The best would be to go pre-sell the idea. But if they cannot do that, what are they brining to the table?
