  Warped extra dimensions can address both the Planck-weak and flavor
hierarchies of the Standard Model (SM). In this paper we discuss the SM
neutrino mass generation in a scenario in which a SM singlet bulk fermion -
coupled to the Higgs and the lepton doublet near the IR brane - is given a
Majorana mass of order the Planck scale on the UV brane. Despite the
resemblance to a type I seesaw mechanism, a careful investigation based on the
mass basis for the singlet 4D modes reveals a very different picture. Namely,
the SM neutrino masses are generated dominantly by the exchange of the
TeV-scale mass eigenstates of the singlet, that are pseudo-Dirac and have a
sizable Higgs- induced mixing with the SM doublet neutrino: remarkably, in
warped 5D models the anticipated type I seesaw morphs into a natural
realization of the so-called "inverse" seesaw. This understanding uncovers an
intriguing and direct link between neutrino mass generation (and possibly
leptogenesis) and TeV-scale physics. We also perform estimates using the dual
CFT picture of our framework, which back-up our 5D calculation.
