I created my first pitch deck for Tipalink (and first one ever!) and had a chance to present it to a potential investor last week. The overall response was "there is something there... I don't know what it is yet... I want to more fully understand it...". The feedback on the general idea was positive, as it has been from almost everyone I've talked to. But not being technical, they were not clear on how the implementation is unique versus competitors. They wanted to know if it can be protected through a patent.
