The two‐derivative approximation to non‐critical strings is used as a qualitative tool to find solutions dual to four dimensional CFTs with matter in the fundamental. Two solutions are discussed: an $AdS_5 \times \tilde{S}^3$ , which is dual to an = 1 SCFT only for a ratio of ${{N_f}\over{N_c}}$ and an AdS 5 which is proposed to be dual to = 0 QCD in the conformal window. All solutions have curvatures of the order of the string scale. This contribution is based on [1].
