Pardon my ignorance, but what made this a great idea? I'm not overly familiar with the company, but it seems like yet another "instead of going to place X to have service Y, X will come to you." It doesn't strike me as entirely novel. And most businesses following that pattern sputter out because they're just not scalable or there's little demand.
$5.25 MM seems like an awful lot of money for something with seemingly few exit opportunities. So I assume there's something I'm missing here.
