After spending the last three-and-a-half years serving as the digital agency for Capital One, 360i will be defending the biz. According to the folks on the Spy line, the financial institution has issued an RFP for its search/display portion of the account, which has been handled by the aforementioned, Dentsu-owned agency. Sources familiar with the matter, though, tell us that 360i is “not concerned” about the RFP, which we’ve been told is a federal requirement that needs to be issued every now and then. Our sources add that 360i has maintained an “excellent relationship” with the client and will be defending the account. We’ve yet to hear back from Capital One on the matter, but we’ll update if and when we do.
