Startup WhoIsLike.it is a website search engine. You enter a website URL and WhoIsLike.it searches the Web for similar websites, providing a thumbnail image and URL. You can then choose one of the results to search for similar sites to that one as well.

It's a nice concept and results seem to be fairly accurate. The thumbnails work about half of the time, so that could use some refining. And the site suffers from what most start-up search engines do - a lack of inventory. Hopefully as the site grows, they will index more sites and return even better results. The site is based in Berlin, Germany, so some sites are in German. Overall, it's a pretty good tool for finding some sites you might not know about. It's a good site to keep an eye on.
