I will describe a perturbative framework for the construction of conformally-compactifiable, hyperboloidal initial datasets for the Cauchy problem in General Relativity via Friedrich's Conformal Constraint Equations. As an application, we construct such initial datasets as (non-linear) perturbations of the standard hyperboloids of the Minkowski spacetime. This is work done in collaboration with Jarrod Williams.
