> I guess you are in a tough position because you are trying to provide real world examples of a category you are hoping to define, but in this case, perhaps it's best to wait for some clear real world examples instead of muddying the waters like this. I fear that reading this, most people would conclude that outcome-based billing is just a way to define your usage-based pricing, rather than something that needs a platform like Skope.
You're right in that the cases of real-world examples are rare, but I believe it's only in software. The concept of outcome-based pricing have always existed throughout different work for a long, long time – think about test-prep service that promises to only need to pay if you get X score, real-estate agent that carry commission as a % of sale price, etc.
I think this instills confidence in something like this and makes me wonder why such pricing models haven't been applied to tech yet.
