Using the vector-exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangian, and has produced realistic results for Ωc,Ξc,Ξb and the hidden charm pentaquark states, we study the meson-baryon interactions in the coupled channels that lead to the Ξbb and Ωbbb excited states of the molecular type. We obtain seven states of the Ξbb type with energies between 10408 and 10869 MeV and one Ωbbb state at 15212 MeV.
