Mobile search firm ChaCha—which lets users call or text message a query and receive an answer shortly afterwards—has raised another $7 million in funding, according to an SEC filing. The round comes five months after ChaCha disclosed a $4 million round—and ten months after it raised $12 million. The latest filing lists past backers, including former Compaq CEO Ron Canion, as directors. A company representative, however, would not say who provided the cash, which brings the startup’s total backing to more than $40 million. He did, however, happily provide figures detailing the company’s growth, including that the number of questions the service has answered is up 191 percent this year.
