Bristol produced a blistering first-half performance to get their European Challenge Cup campaign under way with a 19-5 win in Perpignan.
Early tries from Charles Piutau and Fitz Harding, both converted by AJ MacGinty, gave the Gallagher Premiership side a commanding 14-0 advantage.
And when 19-year-old Joe Jenkins crossed on his European debut after gathering a Harding kick out wide, Bristol looked set for a comfortable night in the south of France.
But Eru Shahn crossed for Perpignan on the stroke of half-time after a clever line-out and the home side largely dominated what proved to be a pointless second period.
Stade Francais hit back from behind to beat Benetton 24-14 and make a successful start at Stade Jean-Bouin.
Benetton led 14-10 on the hour mark after Siua Maile went over for their first try, but Jeremy Ward put the hosts back in front within two minutes, and a further try from Lester Etien sealed their win.
