I think it's important to consider the answer to this question when picking a co-founder. Is your executive team really working towards the same vision of the future, during and after success? Perhaps the money is almost irrelevant because the journey itself is the vision. But depending on the business, that's not always the case. Some people build great businesses just because they are good at it, and they know other people need it - not because they enjoy it or are passionate about it.
Start new products and services to reach more people
It is an excellent question to ask a prospective cofounder, a touch of madness in the answer can reveal how inspired,motivated, but most of all, grounded the person is and more madness than youcan handle will show you in advance why not to start a relationship destined to sour before bearing fruit. Compliments for asking.

I like to aim low.
That said, I am doing what I'm doing because I'm passionate about it.
Forget passionate. More like obsessed. I can't imagine not working on these projects.
I feel the first thing is to strategize on different sector in the company you are founding. This will enable you to apopri each fund to each departments, needs to enable the growth and sustainability of the company. The money itself should be reinvested in the business or should be divested depending on what's on the table.
I feel you should have asked the different question here. The title says "What you do with the money?", but what the actual detail asks is "Should we consider if our visions align with a co-founder/co-founders early on?" and the answer to it is without a doubt YES. As you are a father of 8, you must have a pretty incredible wife whose vision towards future aligns closely to yours - which is have as many children as you can :) The same is matching with co-founders to achieve whatever you want to achieve founding a company.
And what to do with the money? Give it to me - i know very well what to do with it.
I cannot see any relevance in this as a criteria for selecting a co-founder. Spending time talking about the exit windfall, given that most startups fail and very few ever see a $100 mm exit let alone a billion exit will contribute to your failure. You need people in a battle that can handle themselves and their roles in that battle, not one you might engage in some day.
I find it very rare that people ask each other what their ultimate 5 or 10 year goals are. Most personal interaction tends to be transactional or based on relationships (e.g. co-workers) established by other visionaries.
I think it is useful to find how a founder's vision for his company fits in with his own personal character development objectives for himself as a human being.
Gabor has some strong visions, for sure!
A few of my own passions tend to be counter culture, so it usually pays not to share them until I'm intimately acquainted with the other person. I will say that I have definite plans (in mid-execution) to start my own country and grow cannabis to use as a food source (is that part of life extension research I wonder?).
