Fuchi and then Novatech, were the first corp to officially have Cybermancy, however, I believe the Azzies knew it as well, since Blood magic is a speculated requirement. I imagine the vampires know cybermancy because it gives them a safety net for net essence loss. The speculation is that cybermancy prevents death via essence loss, so if a vampire even without cyberware could still use the cybermantic ritual to prevent her own death.
