Search investments don’t cool — Cuill secures $25M

Google is dominating the search business. New numbers from Hitwise suggest Google controlled over 67 percent of all U.S. searches in March — its highest number yet. That apparently isn’t stopping some big time investments in field.

Search start-up Cuill (yes, as the title suggests, it’s pronounced “cool”) has secured a large second of equity financing. The company is currently in stealth mode and little is known about it. On its bare-boned site, the company does promise to be “pioneering a new approach to search.”

There is also an about page for its web crawler bot, which it has named Twiceler.

The company certainly has the right pedigree. Its founder and chief executive, Tom Costello, formerly worked at IBM where he developed the WebFountain Internet analytics engine to survey unstructured data on the web. Prior to that, he created the late 1990s search engine Xift. The two other founders, Anna Patterson (who also serves as president) and Russell Power, both previously worked at Google where they were instrumental in TeraGoogle, the large search index.

The rest of the team is sprinkled with alumni of Google, IBM, eBay, Alta Vista, Xerox PARC, the Internet Archive and Stanford University.

This latest $25 million round was led by Madrone Capital Partners. The Menlo Park, CA-based company previously secured an $8 million round from Tugboat Ventures and Greylock Partners.
