Hi Ben, I appreciate your concern about scaling your service but I think you should consider a fremium business model that allows you to accommodate more free users at lower cost. Instead of logging tens of millions of events for free users, you could log just a subset, which will allow you to use far fewer servers whilst allowing free users to "evaluate the usefulness of your new service". It will also make sure that the future of your startup is not wholly dependent on external investors. We've done something similar with Trafficspaces. We run our service off Amazon's cloud system, which gives us a lot of flexibility. If you need assistance on how to structure your freemium model to make sense, send me an email at niyi [at] trafficspaces [dot] com.
