I'm trying to figure that out as well. A poster pointed out that the Anavex logo is not displayed along with all of the other companies Ariana is working with.
I want to say that I remember it being there, but am not completely sure. Does anyone remember it being there? In the Ariana news section, the collaboration with Anavex pr is still there. It would be strange if the logo was removed.
I don't know all of the companies listed there. Could it be that Ariana has been working with so many companies that they only wanted to display the most prestigious our valuable ones?
