Ask HN: YC for non-consumer technology startups?

Most of the high profile YC success stories seem to be consumer-facing, web and mobile startups. Others, like Heroku, are still tightly bound to that same business community, serving mostly agile web based startups.

What do people think about YC for other business types? I'm particularly interested in disruptive technology innovation in established, well financed industries.

Questions:

* Has YC been interested in opportunities like this?

* Would YC be as helpful for opportunities like this?

* Are there any notable success stories?

Thanks!
