One of the best understood AdS/CFT incarnations relates tensionless $k=1$ strings on AdS$_3$ to a symmetric product CFT$_2$. I will discuss an exact duality between string theory on a spacetime which is not asymptotically AdS and a non-conformal field theory. The bulk theory is constructed as a marginal deformation of the $k=1$ AdS$_3$ string, while the spacetime dual is a single trace $TT$-deformed symmetric orbifold theory. As evidence for the duality, I am going to show the exact match of the one-loop bulk and boundary torus partition functions.
