About the project

Ingrezo is a ticket sales and event management platform built from scratch for the way events work in Brazil. On one side, organizers create, sell and track everything in real time. On the other, the audience discovers the event, pays with PIX, card or boleto and gets in with the ticket on their phone. There is a promoter system with commissions, bulk complimentary tickets and even native crowdfunding campaigns. And since event gates rarely have good internet, check-in works offline and syncs once the connection is back. Under the hood, a modern full-stack TypeScript application with an end-to-end type-safe API, installable as a PWA.

Complete Brazilian payments: PIX, card and boleto with transparent fee calculation
Promoter/affiliate system with commissions and per-promoter metrics
Real-time sales and revenue dashboard, with conversion funnel
Native crowdfunding campaigns integrated into the same payments base
Multi-organization and team collaboration with granular permissions
End-to-end type-safety (tRPC), from database to screen
A complete product, in production, with versioned releases

Leonardo Gomide CPO · Co-founder

Role Product, full-stack development and infrastructure

“Ingrezo was born from a need of my own. I'm a DJ, I've organized events around my region, and I always missed a simple tool for a solo producer to manage ticket sales for small and medium events. The big platforms are expensive and way too complicated for someone doing everything alone. So I built my own, from scratch: data model, screens, payments, deployment, all of it. I wanted it to be easy to use without giving up cutting-edge technology, and that guided every decision, from PIX at checkout to the real-time sales dashboard. The part I'm proudest of is the offline check-in. Anyone who has worked an event gate knows good internet is rare there, so the system validates tickets without a connection and syncs later. It's the kind of detail you only notice when you've lived the problem.”
