Venture capitalists are convinced that the tween market is a big money-maker for wireless operators. MVNO Kajeet has collected a massive $27 million in first round VC money to target pre-teens to early teenagers. Not much is known about the company's plans, although we know that all the founders have children. Kajeet is an anagram of the first letters of the names of the company founders' children. Kajeet will offer prepaid services and promises that kids who use the service will enjoy a full range of features, "while their parents will have access to services that enable them to stay connected with their kids on every imaginable level." Meanwhile, Japanese operators are hoping to put phones in the hands of children who are as young as 5 years old because they can't find anymore customers to tap.
