We report the discovery of two young massive B-type run-away stars. A TESS lightcurves show that the cooler one of them to be a SPB pulsator while the hotter one is an beta Cep pulsator. We present a quantitative spectral and kinematic analysis making use of their Gaia parallaxes. We also present a census of pulsation properties of 41 B runaways studied in the same way as the nwe discoveries.
