That's what they claim. And what Brad said is correct. According to the CEO (who is also CEO of LCC) their software is much more granular than other search engines. For example, when they scour NYT, Twitter, Blogs, etc. they are able to create about 100 semantic tags for every 1 that most of their competition does. This is how they're able to create so many Q&A pairs. They also incorporate real time keyword search along with the Q&A pairs that they have, which is something that (AFAIK) isn't done by any other company.

it's sort of hard to classify swingly as a typical startup... it's more like a company incubated within a larger corporation.. they are licensing TONS of data from their parent company, which has been collecting this type of data for 10+ years or something like that
