In product as a platform, you may understand that there are problems in a particular space, but you may not understand the problems. However, you may understand how a platform might enable the solving of problems, while not really understanding all the problems that will be solved themselves. Generally to be sure of this you should see at least 2 or 3 solutions that you could have conviction in, but understand that entablement would solve very many tangential problems to those you have conviction in is more important. You can somewhat use this to size a future ecosystem market, but you have to be wary about your predictions of the number of solutions you enable. You're also very much fighting too early or just right in terms of timing. Looking for solutions to problems will help you judge the value of the capability, but trying to predict all the applications of those solutions is a fool's errand.
