The New York Times > Technology > New Company Starts Up a Challenge to Google "Google executives have long conceded that one of their great fears is to be overtaken by a more advanced Internet search technology. Vivisimo, a company founded by three former Carnegie Mellon University computer scientists, is hoping to prove that Google's worries are well founded.
Four-year-old Vivisimo plans to start Clusty, a free, consumer search service based on results from Yahoo's Overture engine, Thursday.
The new Clusty service for consumers, which will be free and supported by advertising revenue, uses a similar organizational structure. But it also presents a series of tabs enabling the user to see results from sources besides the general Web, including shopping information, yellow pages, news, blogs, and images."
So... it's like A9?
