We dropped the free trial and we saw revenue increase during the first week.

Instead of having a trial for 14 days, I replaced it with a 14-day money back offer. Same kind of risk reversal, but now people were actually deciding whether to continue or not right on day one, instead of the "maybe" that would come back in two weeks from now but wouldn't actually come back.

Has anyone else replaced trials with guarantees before, and did it work out after the first burst of enthusiasm?
