Joseph at our sister site paidContent.org reports Cuill, a start-up promising “a new approach to search”, has raised a big $25 million second round led by Madrone Capital Partners. Still in stealth mode, the company’s angle is that it can index the web more economically than Google - a mighty claim, if ever there was one. Though based in Menlo Park, California, note that Cuill’s co-founder is Tom Costello from Louth on Ireland’s east coast, who has started the company along with wife Anna Patterson, ex of Google (NSDQ: GOOG). Costello has a Stanford computer science PhD and is an IBM search alum. No word on when Cuill will be unveiled, though. Release.
