Although there are many good ideas out there, aren't you safer to invest in an ICO which already has a functioning and proven product? ROI is much more likely in this scenario
If you find an ICO which can offer its product then send here the link, I think that you will find many investors.
ICOs with product is not for small investors, good example is Telegram ICO.
I think Romad may be in full compliance with your standards. They are a blockchain anti-virus software. I have applied for their trial products and have been trialing for 2 months. If you are interested, you can take a look.
