About TchêGrana — collaborative finance SaaS
Shared budgeting for families & couples — money managed together.
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) • Handover support & documentation STATUS • Live in production (client, admin, landing and API all deployed) • New project — pre-revenue, sold as a complete, deployed codebase + brand ready to grow 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.

Reason for selling
I built TchêGrana to solve a real need for my own family. It's complete and deployed, but I don't have the time/focus to take it to market — I'd rather hand it to someone with the bandwidth to grow it.
