Is There a Canvas for Business Model Canvas?

Business model canvas is great and I think a lot of companies are using it but it's I've started to do something as a defining business models which is something that you actually get into in this API world. It's about kind of mapping out all the different stakeholders or constituents of a digital ecosystem and seeing what types of value they exchange. This can be a really powerful way of coming up with visual business models that's very actionable whether you want to refine what you're doing or find new opportunities and gaps.
