Build an exclusive mobile community for your business

Came across this product through an /r/startups thread - they have a pretty funny Twitter feed. I think the copy on the page needs some tweaking but it looks like an impressive mobile bridge to increase engagement within your user base, hyper target certain segments with personalized offers, and so on. As a business you can choose to offer free "membership" or scale up from there. I think there's a lot of potential with this product but I'd love to see some use cases on site. From their website: "INTRODUCING THE FIRST MOBILE MEMBERSHIP MARKETPLACE. Build a membership community, where your most loyal fans access exclusive perks and promotions unavailable anywhere else. Think of it as your very own red carpet club or VIP lounge. Turn your customers into members with a suite of tools designed to promote long-term loyalty and engagement. Membo is redefining membership."
