I'm sure something like this exists, I see no reason to reinvent the wheel here. But finding a good one is challenging.
We have a product, we have identified a market. We have potential customers that are waiting for us to deliver them a 'package,' or something that can summarize the benefits the product will give the customers, so they can take that to their bosses and team.
But we don't have absolute clarity on the product itself (its current state, which is totally fine, vs it's future state, which would be optimized for the customer). We don't have a perfect way to convey these things to the customer (that take into account, say, tone, imagery).
