After a brief introduction to factorization in exclusive B meson decays and its formulation in soft-collinear effective theory, I discuss the derivation of light-cone sum rules from correlation function within the effective theory. As an example, we study the B -> pi transition form factor, which is one of the hadronic input functions for the determination of |V_ub| from semi-leptonic or the CKM angle alpha from non-leptonic B decays.
