I am pretty sure that the name of the company that POET signed the agreement with, is HE Capital Markets.

The platforms where the content is to be published and distributed will be mainly IHub but also Wall Street Silver Services. That's not a company.

However, I couldn't find anything via Google that would fit the description of that "Plattform" or Service in relation to POET other than links to the last PR and/or in relation to discussions around the metal silver. However, how it is worded it's not referring to a company. It would refer to a platform like Agoracom or IHub. Which I couldn't find in the WWW.
