If a bricks and mortar start up used an ICO to raise the needed capital to get the business operating and profitable (very profitable!) what evidence would you want to see to get a good comfort feeling that it wasn't a scam. The idea is that in return for an investment you would get crypto token(s) which would later be redeemable (after 12 to 18 months) at a high ROI (quite possibly 10X, possibly a little more).

It would be a standard ERC20 token or one created on the WAVES platform. There is no blockchain or anything like that intended.

Would be good to get your feedback.

Cheers
