Editorializing: Why would a spouse be no less entitled to reap the rewards generated by the other spouse's start-up? A relationship, especially a marriage, is inherently two people acting as a unit, so just because one spouse didn't sling PHP and research lambdas all night doesn't mean that either spouse's contribution is more or less valuable. If my spouse accomplished something like this, I'd be thrilled at the success and genuinely looking forward to our life together with much less time and stress investment from both of us, since that means that I was also picking up a lot more of the "home life."
