Previate Esta

For this hackathon, we will be presenting Previate Esta, a social entertainment app designed to connect people, events, and nightlife experiences. It began as a pre-party game and evolved into a full social platform where users can discover bars, parties, shows, and activities to enjoy with friends.

Previate Esta has been live on both the Google Play Store and the Apple App Store for over 6 years, establishing itself as a real, proven, and consistently growing product.

To date, it has accumulated approximately 2,000,000 total downloads, with over 100,000 monthly active users and a digital community of more than 1,000,000 followers across social media.

Our goal for the hackathon is to demonstrate how a widely used, established application can integrate new technologies —such as Web3 identity, decentralized verification, and secure user-to-user messaging— to further enhance authentic connections within nightlife and social experiences.
