This brother and sister team got rich quick on the Internet by coming up with the social networking site, MyYearbook.com, a digital idea based on good old-fashioned yearbooks. Initially they got started with a quite healthy $250,000 investment injection from their older brother Geoff.
Now their website, which has subsequently merged with Quepasa, is worth at least $100 million, largely from the advertising revenue they are able to get via the site. Individually the pair is worth at least $30 million each, probably more.
