TrialPay, a San Jose, CA-based developer of a payment platform that allows a company’s customers to access premium content and services by participating in relevant offers, has raised $3.1 million in first round funding, according to an SEC filing, picked up by PEWNews. The round was led by Battery Ventures. The company has not launched fully yet, but from the scant description on the site, it seems like an affailiate marketing service which will hawk, among other things, content offers. The CEO and founder is Alastair Rampell.
