- Company Formation (thefunded and a few law firms come close but it's not marketed well or as complete/one-stop/no-fees-added as it could be)

- Seed finding (just as hiring someone to put up and manage your company's FB, twitter, etc. in a onestop, but this hits angellist, s.co, and the other half-dozen I can't think of)

(kinda tangential to your first list but very applicable for me at least)
