Employing a freemium model for your startup is a complex affair. You get the users/customers (hopefully), then have to figure out how to best generate revenue. Join us to hear Peter Fishman, Yammer's Director of Analytics, discuss how companies that employ a freemium model should evaluate price, revenue, cost and profits. Peter will leverage his experience at Playdom and Yammer to provide examples in both consumer and enterprise spaces, as well as more traditional examples that you'd typically see in Berkeley textbooks. Come on over to Yammer HQ (1355 Market St. 3rd Floor), enjoy our sweet digs and learn some stellar stuff. **Beer, wine and heavy apps to be served so come HUNGRY!
