We present measurements of the coronae of two AGN from hard X-rayobservations made with NuSTAR: ESO 103-035, a moderately to highly obscuredsource with significant reflection; and IGR 2124.7+5058, a radio-loud sourcewith a very hard spectrum. Using an exponentially cut-off powerlaw model forthe coronal emission spectrum gives a high-energy cut-off of $100_{-30}^{+90}$keV for ESO 103-035 and $80_{-9}^{+11}$ keV for IGR 2124.7+5058, within thetypical range for AGN. Fitting with physical Comptonisation models shows thatthese correspond to a temperature of $22_{-6}^{+19}$ and $20_{-2}^{+3}$ keVrespectively. These values are consistent with pair production limiting thecoronal temperature.
