We study the relationship on Weinstein domains given by Weinstein cobordism. Our main result is that any finite collection of high‐dimensional Weinstein domains with the same topology is Weinstein subdomains of a ‘maximal’ Weinstein domain also with the same topology. As applications, we construct many new exotic Weinstein structures, for example, exotic cotangent bundles containing many closed regular Lagrangians that are formally Lagrangian isotopic but not Hamiltonian isotopic and a new exotic Weinstein structure on Euclidean space. A novel feature of our construction of exotic structures is the use of results from symplectic flexibility. We also describe a similar construction in the contact setting which we use to produce ‘maximal’ contact structures and extend several existing results in low‐dimensional contact geometry to high dimensions. We prove that all contact manifolds have symplectic caps, introduce a general procedure for producing contact manifolds with many Weinstein fillings, and give a new proof of the existence of codimension two contact embeddings.
