KR8OS - https://bitcointalk.org/index.php?topic=2322677.0 (https://kr8os.com) is the one I have my eye on.

Their team is very solid and they seem to have a legitimate blockchain solution. They are advertising focused and so they are thinking of using the blockchain to bring transparency on a very big gray-area in the media space. Have a look! Their presale is in about 2 weeks and they have a really good price for their sale period. Please note I work for KR8OS.
