Thanks for the comment Peter :) The best way is to build a great product that people want and love to use so they promote you through word of mouth. As most startups we don’t have a huge marketing budget so we have to rely on just hustling and trying to get users any way we can. If you have a startup at the early stage you should concentrate most efforts on getting good PR and testing one or two channels and finding what works. For us referrals have been working great so we continue to push that.
