São Paulo's nightlife platform

I co-founded and built REVO, the platform that runs São Paulo nightlife. Venues use the dashboard for guest lists, QR door check-in, tickets, reservations, digital menus and CRM. The public uses the app.

House AI

Customer service on WhatsApp and Instagram

AI customer service on each venue's WhatsApp and Instagram, always anchored to real dashboard data. The venue keeps its own number.

AI phone survey interviewer
