This type of market research was previously only accessible to companies that could drop 10k or more on these surveys. This tool will help entrepreneurs validate ideas they were unable to test because it was cost prohibitive.
As an aside, google launched this about 6 months ago and pretty much has everyone in that business scared. Ultimately it all boils down to having profiles on a lot of users and selling access to them. Google's user base (and what they know about them) dwarfs what everyone else has combined. If they wanted to, with a bit of effort they could own that market in 6-12 months.
