TchêGrana — collaborative finance SaaS

About

TchêGrana is a production-ready SaaS for collaborative personal finance — built for

families, couples and groups who want to manage money together with transparency,

while keeping individual privacy. The pitch: "the control of a spreadsheet, with the

ease of an app."

It's fully built and live in production — client web app, admin panel, marketing

landing, a Java backend, PostgreSQL and Stripe subscriptions (monthly + annual). Not a

prototype: real auth (email + Google), payments, webhooks, transactional email and CI/CD

are all wired and running.

WHY IT'S INTERESTING

• Underserved niche: shared/family finance for the Brazilian market (PT-BR, BRL, LGPD-aware).

• The hard parts are done — Stripe billing, multi-tenant workspaces, roles/invitations,

statement import, recurring transactions. Huge head start vs. building from zero.

• Free public financial tools (calculators, financial diagnosis) already act as a lead magnet.

KEY FEATURES

• Shared & private accounts, transactions, transfers, balance adjustments

• Budgets, savings goals, recurring expenses/installments, cash-flow forecast

• Income-based expense splitting (contribution split)

• Bank-statement / spreadsheet import (.xls/.xlsx) → auto-categorized entries

• Multi-member workspaces with email invitations & roles

• Fast dashboards: monthly surplus, evolution, "where I spent", net worth

• Light/dark mode, fully responsive, recently redesigned to a mature financial-SaaS UI

TECH STACK

• Frontend: React 19 + TypeScript + Tailwind (client), Vite (admin), Recharts

• Backend: Java + Spring Boot, PostgreSQL (Flyway migrations), JWT + Google OAuth

• Payments: Stripe subscriptions, webhooks, billing portal — monthly & annual plans

• Infra: Docker + Caddy (HTTPS) on a VPS, GitHub Actions CI/CD, SMTP transactional email

WHAT'S INCLUDED

• Full source code (client, admin, landing, backend) with git history

• Domain tchegrana.com.br + subdomains

• Deployment setup (Docker, CI/CD, infra docs) and Stripe plan configuration

• Brand assets (logo, favicon, design system)

STATUS

GREAT FOR

A solo founder or small team wanting a ready-to-launch fintech in the Brazilian

family-finance niche — skip 6–12 months of full-stack build and go straight to growth.
