"Sambotestet", a Facebook app that determined; who is your perfect cohabitant? The test result was made possible through an advanced technical solution, taking full advantage of the Facebook API. A number of factors were compared for example common interests, tags in pictures, events attended etc. The data was compared in real time between different Facebook accounts. When the test was completed the perfect "sambo" (cohabitant) was presented with the help of a picture where the user and the perfect "sambo" were tagged together. After that the participant could of course share the result.

Launch was made through a sponsored post, worth $300, this little push kickstarted the viral effect. In less than a month, the number of likes increased from 5000 to 370 000. People using Sambotestet spends an average of 2 minutes of active engagement.
