What we do
We build what’s next.
HIGH5 is a software and game development studio based in Warsaw, Poland, building games, AI-powered applications and digital products from concept to launch.
From addictive mobile games to intelligent applications, we turn concepts into products people want to use, play and come back to.
Game Development
Play. Compete. Repeat.
We develop games, including mobile games built in Unity, from original concepts and core mechanics to polished products ready for players worldwide.
AI-Powered Apps
Smarter ideas. Real impact.
We build web and mobile applications that use AI to solve real problems, automate workflows and unlock entirely new possibilities.
AI-Powered Development
Build faster. Think bigger.
We integrate AI into our development process to accelerate prototyping, explore more ideas and bring ambitious projects to life.
From Concept to Launch
One idea. Every step.
From initial concept and product strategy to design, development and launch, we help turn ideas into working software: web apps, mobile apps and SaaS products.
AI-powered development
Build faster.
Think bigger.
AI is more than a tool. It expands how we explore ideas, prototype experiences and build digital products.
- The machine
- AI-assisted workflows that speed up prototyping and production.
- The player
- The creative experience we build it all for.
Our work
Built to be played.
Made to be used.
Every project starts with a challenge and an opportunity to create something better.
We develop original games, AI-powered applications and digital products designed around real users and meaningful experiences.
Our approach
Less talk.
More building.
Great products don’t happen by accident. We combine creative ambition, technical expertise and AI-powered workflows to move from idea to execution.
Think boldly. We challenge assumptions and explore unconventional solutions.
Prototype early. We test ideas before investing in full-scale development.
Build intelligently. We use the right tools and technologies for every project.
Keep improving. We learn from feedback, iterate and refine the product.
From idea to reality.
Step 01: Discover
Define the problem, audience, concept and product goals.
Step 02: Prototype
Test the core idea with a working prototype.
Step 03: Build
Develop, integrate, test and refine the product.
Step 04: Launch & Evolve
Prepare the release and continue improving the product.
We believe
A more playful tomorrow.
We believe technology should unlock creativity, not limit it. We combine game design, software development and AI-assisted workflows to build products that are useful, engaging and memorable.

FAQ
Questions?
Straight answers.
What we build, how we work and where to find us.
What does HIGH5 do?
HIGH5 is a software and game development studio based in Warsaw, Poland. We build games, AI-powered applications and digital products, and we take them from concept and prototype to development and launch.
Does HIGH5 develop mobile games?
Yes. Loot Crawler, our mobile dungeon crawler for iOS and Android, is in production in Unity 6 and C#. Its game rules run in a pure C# core covered by tests, and a bot that plays thousands of simulated expeditions checks the game balance in continuous integration.
What kind of software does HIGH5 build?
Web apps, mobile apps and SaaS products, often with AI inside. TARN is an AI memory and story layer for tabletop RPGs, open as a web beta with iOS and Android apps in testing. Onboardly is a live SaaS for digital employee onboarding in Poland.
What technologies does HIGH5 use?
We choose the stack to fit the product. Our current projects use TypeScript, Next.js, React, Expo and React Native, Postgres and Vercel for web and mobile apps, Unity 6, C# and .NET for games, and generative AI models for speech, text and images.
Does HIGH5 use AI in development?
Yes, in two ways. We build AI into products: TARN turns recorded game sessions into illustrated, comic-style chapters. We also build with AI: on TARN, AI coding agents work from a versioned specification and every change is checked with type checks, linting and tests. On Loot Crawler, coordinated AI agents handle design, programming and QA tasks, with a person making the calls.
How does a project with HIGH5 start?
With a conversation about your idea. We work in four stages: Discover (define the problem, audience, concept and goals), Prototype (test the core idea with a working prototype), Build (develop, integrate, test and refine) and Launch & Evolve (release and keep improving). Write to hi@high5club.pl.
Where is HIGH5 based?
In Warsaw, Poland. HIGH5 is a brand of High5Club Sp. z o.o., ul. Michała Kleofasa Ogińskiego 11 lok. 9, 03-318 Warszawa, registered in the Polish National Court Register under KRS 0000940990.
