TAGonSoft, founded in 2013 by mobile developers with over a decade of experience. Since 2021 we focus exclusively on Flutter — one codebase for iOS, Android, web and desktop.
The best proof of what we ship: a real-time game and an AI product in production, both live right now.
Real-time multiplayer backgammon — Flutter, Dart and Go
Classic backgammon against a real opponent, with matchmaking and rankings. Game, admin panel and Serverpod backend in Dart, plus a Go microservice for the real-time match traffic. Play in your browser or on iPhone and Android.
AI table extraction from PDFs and photos — live in production
Upload a PDF or snap a photo of a document and get clean CSV tables back in seconds. A vision LLM (Google Gemini) does the reading; our PHP backend, Flutter web app and guardrails make it reliable enough to charge for.
Over a decade building native mobile apps, plus 5+ years of Flutter in production. We are not a generalist shop that learned Flutter yesterday — Flutter is our primary stack and we know where the edge cases live.
Weekly updates with real progress, demos you can touch, technical decisions explained in language you understand regardless of background. No jargon, no hiding.
Our estimates include realistic buffer for integrations, code review and QA. When we say six weeks, we ship in six weeks — or warn you well in advance if a risk emerges.
Transparent pricing, no hidden hours. We recommend the smallest scope that validates your hypotheses — we prefer an MVP shipped in 2 months over an 8-month project that never sees daylight.
We have worked with Alex, CEO of Tagonsoft, and his team first as consultants after that as developers of our iOS App for over a year. It proved to be a valuable support throughout the development of the App before being taken in hand by our internal team. Alex and his team are totally reliable, serious and honest, rare qualities to find in this field. Cynny is grateful for the contribution and the availability in every critical moment.
CEO, Cynny.com
