It is Iconomi, and they have two coins: ICN and BLX.
You can buy ICN on Kraken but BLX can be purchased only on ICONOMI website.
BLX is a market index that is made out of a diversified investment by Iconomi company. My BLX investment has returned 20% profit since 2 weeks ago and I just invested in ICN to see how that one goes.
Both ICN and BLX are ERC20 tokens so you can safe guard them in your Ethereum wallet e.g. MyEtherWallet.
BLX return of investment has been about 800% since 6 months ago which is remarkable for an index.
