In this article, we give new results in the startpoint theory for quasi-pseudometric spaces. The results we present provide us with the existence of startpoint endpoint, xed point for multi-valued maps dened on a bicomplete quasi-pseudometric space. We characterise the existence of startpoint and endpoint by the so-called mix-point property. The present results extend known ones in the area.
