  So-called 4321 gauge models at the TeV scale with hierarchical couplings
reminiscent of the Standard Model Yukawas offer a coherent combined explanation
of the recent $B$-meson anomalies. In these proceedings, based on
arXiv:2203.01952, we discuss how such models could arise from a multi-scale
theory of flavor, based on a warped fifth dimension with three branes. This
higher dimensional construction provides a natural description of flavor
hierarchies, addresses the electroweak hierarchy problem, and allows for the
Higgs to be identified as a pseudo-Nambu-Goldstone boson emerging from the same
dynamics responsible for the breaking of 4321 gauge symmetry.
