I'm going to talk this through in hopes of finding some insight along the way. Warning, stream of consciousness ahead...
What I'm talking about has more to do with rethinking why you wanted to start your own business in the first place. Be prepared to rethink what marriage is for, what problem marriage is the solution to.
Genesis teaches us it is not good that man should be alone. Women were given to us to be helpers in life.
Ecclesiastes points out wives are here as part of our reward for the toils in life (along with food and wine) and are to be enjoyed.
I can also think of at least one commands given that require a woman: 'be fruitful and multiply'. Any others?
There is also your specific talents which may lead you to undertake certain missions in life.
Not sure where to go with this right now.
You're trying to find the right combination of value to take to the market, and the way you know you're succeeding is you make more than you spend.
In practical startup theory, pivots come about because of a chicken and egg problem: you don't know what product your market wants, but you can't find that out until you have something to sell them. So you do SOMETHING you think will meet needs and provide value, get it out there (sooner the better) and start getting feedback. Should you not get market traction or strike upon a need/demand greater than the current, pivot to something else. Sooner the better; fail faster. Stay lean. Bootstrap from success.
We have a similar chicken and egg problem in relationships. You never know what lies in the heart of [wo]man, what experiences/motives/sins lie uncovered, what trouble lies ahead, how you'll all knit together or how you'll react to adversity. The only way to know is to do it.
I can think of
four things you can pivot on in a relationship: the wife, the roles, the leadership methods, and the mission. Am I missing any?
The woman...Although the woman does constitute a large part of the eventual success/fail, pivoting through them post marriage isn't a good option. Nor is fail faster exactly a sound theory for lasting marriage. I don't think this is what you're getting at.
The PUA community takes a pivot approach to forming a long term relationship. But they pivot from one woman to another, looking for that worthy candidate; not exactly a Godly model. And they tend to shoot themselves in the foot, never being willing to put in the hard work lasting relationships need and not realizing that the skills needed for that are different than what it takes for hooking a woman for a fling.
The roles....presumably you have need of a helper and work for her to do. But maybe what you first conceive doesn't work. Don't be rigid. Be willing to shake things up, swap assignments around, etc. If she is young, she may not even know where her gifts lie, may need a fair amount of training and practice. Watch expectations. She shouldn't come into this with a rigid idea of what life must be like; to miss the forest for the trees. The point is to be his helper, however he may decide. That may change. She's not marrying a role (i.e. cook) or a title (banker's wife, engineer's wife). All those may change. She is marrying a servant of God and God may take him and you places you could never have imagined.
Leadership methods....there are many different styles of leadership, management, and discipline. Every person responds differently and takes a different style. She's not your first wife, doesn't share your history and won't respond the same way. You're starting from square one, but at a higher level of difficulty due to the more complex social dynamic. You need to come to know her so you can lead her in an understanding manner.
The mission....hopefully the husband has a purpose to serve God for His glory. But your specific vision for life to serve that purpose, not sure how that would pivot in relation to marriage. What missions he may go on to that end are likely to change over time. It may be that the talents your wives bring will change what missions you entertain. Raising children and working to spiritually lead your wives are their own missions as well.
