RainaCorp — Independent Product Studio

We build software products, and run them in production.

RainaCorp designs, builds, and operates its own platforms — across personal finance, smart homes, media, and self-hosted infrastructure — and takes on a small number of client commissions each year.

Products

Platforms we own and operate.

Not client deliverables — our own products, built end-to-end and maintained in production.

FinPath Navigator Live · v4.1

A personal finance cockpit with purpose-built tax engines for 16 regions — net worth, budgets, cashflow, investments, and an AI assistant in one privacy-first app, on web, iOS, and Android.

Project North Star Live · Self-hosted

A self-hosted library server for EPUB and PDF — like Plex, for books. Automatic metadata extraction, in-browser readers, and reading progress that syncs across devices.

The Lab

Smaller tools, real users.

About

How we work.

The studio

RainaCorp is a UK-based independent product studio. We don't just deliver software — we operate it. Every product above runs in production with real users, which keeps us honest about reliability, security, and the details that only show up after launch.

Commissions get the same treatment as our own products: one team, end-to-end ownership, from first sketch to deployment and beyond.

The stack

Frontend — React, TypeScript, Tailwind CSS
Mobile — React Native (Expo), Capacitor
Backend — Python (FastAPI), Node.js, PostgreSQL
Platform — Supabase, Firebase, Docker, Vercel
AI — LLM integration, vision models, multi-agent systems
