This proceeding is based on the paper 1010.5188 [hep‐th] where we discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate three D‐brane stack realizations of the Georgi‐Glashow model and analyze them with respect to their Yukawa couplings. We show that most/all phenomenological problems that appear in two stack models can be resolved in three stack models. We exemplify with globally consistent Georgi‐Glashow models based on RCFT that these D‐brane quivers can be indeed embedded in a global setting.
