I know of 4 of them.
InvestFeed, Debitum, adbank and Tenx

Tenx is a hold for sure, A lot of risk in the other ones. If they produce their product you might see some good gains but it will be a while (year) down the track before that will happen. Maybe see what the markets are doing by the end of July and hopefully offload them then at a better price then now.
I think there's better option available who have their product working.
