Any 1-topos has an enveloping infinity-topos defined as sheaves of spaces over the 1-topos. But surprisingly, this construction does not send presheaf 1-topoi to presheaf infinity-topoi! I shall explain why and provide sufficient conditions for the envelope to stay a presheaf topoi. Applications includes the presheaves over the simplex category, or G-equivariant presheaves.
