  Quiver theories constitute an important class of supersymmetric gauge
theories with well-defined holographic duals. Motivated by holographic duality,
we use localisation on $S^d$ to study long linear quivers at large-N. The
large-N solution shows a remarkable degree of universality across dimensions,
including $d = 4$ where quivers are genuinely superconformal. In that case we
upgrade the solution of long quivers to quivers of any length.
