We discuss the possibility that inflation is driven by supersymmetry breaking with the superpartner of the goldstino (sgoldstino) playing the role of the inflaton and charged under a gauged U(1) R-symmetry. Imposing a linear superpotential allows to satisfy easily the slow-roll conditions, avoiding the so-called eta-problem, and leads to an interesting class of small field inflation models, characterised by an inflationary plateau around the maximum of the scalar potential near the origin, where R-symmetry is restored with the inflaton rolling down to a minimum describing the present phase of the Universe. Inflation can be driven by either an F- or a D-term, while the minimum has a positive tuneable vacuum energy. The models agree with cosmological observations and in the simplest case predict a rather small tensor-to-scalar ratio of primordial perturbations. Upon coupling the inflaton sector to the (supersymmetric) Standard Model, we examined decay modes of the inflaton, with the resulting reheating temperature around 10^8 GeV.
