Saw this post recently on Sramana Mitra's blog, about this startup called WaterFilters.NET.
Here is the post.
The business model is interesting, and the post says that they have revenues and are growing. I think there could be many more such startups on roughly similar lines, whose business model involves something in the physical world, and not the usual me-too wannabe-Facebook social-networking kind of startup.
