If only Groupon could have patented its business model. The latest entity to borrow its simple and now widely duplicated go-to-market strategy is a new micro lending site called Cogster.  The site combines localized microlending and social media by connecting consumers with entrepreneurs - but  instead of receiving a stake in the company, consumers receive gift certificates for goods and services as their ROI (via American Banker).

Groupon is not the only model from which Cogster has borrowed: shades of the peer-to-peer lending site Prosper and micro lender Kiva are also present. The site lets a businesses set a financial goal to reach by a certain date. Consumers then choose which business they want to frequent by offering contributions - which earn dividend certificates. If the business offers the Double Money option - and most do - the consumer can then redeem the certificate for its face value within 30 days and then receive another worth 50% of the contribution 30 days later and then a second 50% face value coupon a month after that.

What businesses like about the model is that the up-front money isn't a typical loan, but rather is something that will lead to future customer visits. "This is almost marketing in reverse," found Steven J. Bisbee said (via American Banker). "Instead of paying for a radio ad and hoping people come in the door, this is raising money day one and only paying against it if customers continue to come back over time."

CauseOn is another site borrowing from the Groupon model, offering consumers discounts ranging from 50% to 90% - with 20% of revenues slated to a cause of the customer's choice.
