It may be an arguable point, but I think at bare minimum she brings some value via bringing ton of cache and PR with her, so she may be a good fit for a small firm that could benefit from a lot of press and razzle dazzle.

She seems absolutely obsessed with the fashion industry (why did Yahoo need to open an office in Milan and spend $3 million sponsoring the Met Fashion Gala) so perhaps some sort of online fashion store would be a good fit, like Net-A-Porter, Shop Bob or Poylvore.
