Non-linear sigma models on coset superspaces appear in a variety of physics problems, including string theory in AdS backgrounds. In spite of their relevance and remarkable features, the exploration of supercoset sigma models is only just beginning. At the example of superspheres $S^{2N+1|2N}$ and complex projective superspaces $CP^{N-1|N}$, I shall describe some recent results, in particular on the spectrum and certain correlators of supercoset theories. Special emphasis will be put on finding weakly coupled (non-geometric) duals to sigma models with strongly curved bosonic base.
