In this note we study exceptional algebroids, focusing on their relation to type IIB superstring theory. We show that a IIB‐exact exceptional algebroid (corresponding to the group Enfalse(nfalse)×R+$\mathsf {E}_{n(n)}\times \mathbb {R}^+$, for n≤6$n\le 6$) locally has a standard form given by the exceptional tangent bundle. We derive possible twists, given by a flat frakturglfalse(2,double-struckRfalse)$\mathfrak {gl}(2,\mathbb {R})$‐connection, a covariantly closed pair of 3‐forms, and a 5‐form, and comment on their physical interpretation. Using this analysis we reduce the search for Leibniz parallelisable spaces, and hence maximally supersymmetric consistent truncations, to a simple algebraic problem. We show that the exceptional algebroid perspective also gives a simple description of Poisson–Lie U‐duality without spectators and hence of generalised Yang–Baxter deformations.
