At large number of colours, a confining gauge theory becomes a theory of weakly interacting hadrons, with mesons forming a closed subsector. In this context, constraining the masses and couplings of mesons is a well-defined and tractable bootstrap problem. In my talk, I will review the EFT bootstrap and show how it applies to meson scattering. Specifically, I will explain how a few simple but carefully chosen assumptions lead us to an extremal amplitude featuring a Regge trajectory with mesons at all spins, and numerical data remarkably close to real-world QCD .
