Analysis: TrialPay's payment and promotions platform pairs online shoppers with ideal offers. The company had a revenue run rate of $50 million back in March of 2009. We believe, given the rise in virtual currencies and online gaming, we expect the company could achieve revenue in the $75 - $100 million range this year. A valuation of $200 million assumes a multiple of 2x.
