When testing, I realized that at least 80% of users that were really interested with the app were elderly or not 'tech savvy' at all. That said, the landing page - no matter how good it was - wouldn't matter a lot from the user acquisition perspective. Those people can barely use facebook.

My idea was to 'manually' get condo managers to sign up, they are the actual target audience. But the process of calling them, showing a demo and getting them to use cost me some cash. The price target for the service was around 20 USD/condo. I was spending more than 250 to get a deal on a single condo (avg of 88 users/condo).

I still think the ideia is infallible, but a little ahead of it's time. I actually got buyout offers from two large condos in florida, but I couldn't use the source code for my new attempt.
