according to LinkedIn there is only 1 guy named like that in Germany, but still other companies affiliated with than the ones mentioned by Thalion:
Salvador Fernandez Gomez
Geschäftsführender Gesellschafter (CEO) at SALVA-MEDIA International GmbH - HRB 81127
Frankfurt Am Main Area, Germany
That company (founded 2007) is located in the same suburb as Phase 5, but a different street, but then moved to another location, same location of FWD Fernsehwerbung Deutschland GmbH, which went bankrupt since September 6th 2016!
The website DNS entry for this company expired and is now for sale.
no word of P5 on Linkedin, not now nor in the past either, just a hint that indicates he is the same guy, is the fact this account is following Commodore (a tombstone company entry in Linkedin)
Instead of his aggressive response on Facebook that he will sue X Y Z who is critical of the new P5, he can solve all this very simple by delivering the goodies, instead of teasers. And yes, his own FB profile looks...odd...
...too many red flags for me...
