After launching, Saltar was lucky picked up by a local-news. Which send ~2000 visitors to our website. It's surprised me that there were 500+ signups within a week.
Saltar landing page is only one page, with animation that people can play, and a signup form. I learn that since someone else is talking about you, all you have to do in the landing page is showing the signup form. People who visit Saltar were ones that already interested.
