They could also hire some more team members in order to introduce demo version of their platform before ICO. I am sure it would pay off to do that since they would get much higher starting capital trough investments.
A demo is really nice but to hire more team member for this? I am not sure. Would just make sence if they would benefit from them in the complete long run.
But at least some videos where they test the platform would be cool.
Hiring additional team member that has the capability to contribute significantly to platform development would ideal. Imho.
If they didn't have the persons to handle something, the programmers to handle the beta version in this case, hiring another persons could benefit them.
