The ALICE experiment, dedicated for heavy-ion collisions at the LHC, is taking data with proton-proton collisions since November 2009. This contribution summarizes initial operation and performance of the ALICE detector at the LHC as well as first results from pp collisions at 0.9 TeV and 7 TeV. The energy dependence of the charged-particle multiplicity and of the antiproton-proton production asymmetry at mid-rapidity is presented. The strangeness and charm production analysis is discussed.
