I get what you mean but you should also understand most ICOs are done because of the lack of working products. They need funding in order to actually products working.

But anyway, I believe a solid ICO whose team has constantly delivered "working" products is the ENJIN ICO. I used their service as a minecraft server owner before and during my 1 year use of their services there were always lots of updates and enhancements to their platform. I believe they will do really good once they launch their mainnet.
