The Priceless Brazil Guide is a website accessible from any device with a directory of places and activities informed by Brazilians’ social media activity. It’s the best of Brazil, according to Brazilians themselves.

People use the hashtag #priceless when tweeting, checking in, taking a photo, or posting a status update. This behavior supplies the guide’s content. Users can browse recommendations from friends or chosen experts. They can like experiences, tag things they’ve done, or make a to do list.

In just three months, with no paid media support, over 10,000 people registered to use the guide, posting over 1000 experiences.

Since the service is rooted in the activity of its users, it’s constantly growing and evolving.
