We launched OrgPad 10 months ago when we have about 50 people registered recruited from our friends and their friends. We have discovered that even convincing your friends to open your product is difficult.
We are growing ever since, steadily gaining new people. We just broke 1000 users while spending $0 on advertising, mostly our users recommend each other and we are writing posts to various places. Out of these people we have maybe 50 heavy users which is an amazing growth compared to the time when only three of us were using OrgPad.
What are your tricks to finding more users? We believe that building a great product comes first.
