In Bragster you don't place cash bets, you simply "brag" to your friends that you will do something, like turn up at work in your pajamas. You can bet anything you want. It's very video oriented as well, so people can see proof of your dare. Revenues willeventually come from "sponsored brags" created by brands which want to distribute a marketing message in a fun way, and they are looking to license a white label version of the platform. Bragster is biggest in English speaking territories like the UK, US and Canada.Bragster is the re-launched version of Gottabet, a site which won a seed round in 2006 but dumped it's cash bettings model. |  | Series A | Feb 13, 2008 |  |
