I will review the (numerical) S-matrix Bootstrap approach to scattering amplitudes. In particular, I will explain how this approach can be used to bound the space of Wilson coefficients in Effective Field Theories (EFT). I will discuss two notable examples: the chiral lagrangian and supergravity. Remarkably, strongly coupled string theory seems to saturate the bounds imposed by Lorentz invariance, unitarity and causality.
