Just like what was mentioned about Softbank... your investors will ask if you've jumped onto the latest fad:

* Are you increasing your engineering headcount exponentially?

* Does your product have a subscription model?

It's no different with physical products. I've seen investors ask:

* Does your product have a consumable that you can sell for recurring revenue?

* What is your strategy for becoming a primarily software company?

* When will you be moving to China?
