Abstract This review will cover the most recent results from the B factories in the field of heavy quarkonia and multiquark systems. At Belle-II, the first data taking period beyond the Υ(4S) peak energy has been been devoted to the study of the region around s=10.75 GeV, where enhanced transition rates to lower bottomonia suggested the existance of a new exotic bound state. In turn, LHCb keeps discovering new tetraquarks and pentaquarks at steady pace. Most of them are composed by at least one cc¯ pair, but recently also systems with two \ccbar pairs and tetraquarks with open double charm have been found.
