About The Studio

Validated ideas, turned into products that ship

We help startups, entrepreneurs and growing businesses turn validated ideas into focused, reliable mobile applications and games. Our work covers the complete development process: idea validation, project planning, user experience design, development, third-party integrations, testing, launch and ongoing technical support.

Scope Defined Before Code

Functionality, user journey and technical requirements are agreed in writing before development starts, which keeps budgets predictable and prevents projects from quietly expanding.

Built to Survive Launch

Analytics, crash reporting, store compliance and update pipelines are part of the build, not an afterthought added when the first bad review arrives.

  • Full-cycle production: design, art, code, QA and release
  • Native iOS and Android, plus cross-platform builds
  • Playable prototype before the production budget is committed
  • You own the source code, art sources and store accounts

What We Do

Mobile development from first concept to live product

Games, business applications and startup MVPs, delivered against a written scope and a schedule you can plan around. Every engagement includes design, development, testing, store release and the support that comes after it.

Mobile Game Development

Full-cycle production of casual, hyper-casual and mid-core titles for iOS and Android, from the core loop to the store release.

Mobile Application Development

Practical applications that solve a clear business problem: booking, client portals, internal tools, e-commerce and subscriptions.

MVP Development for Startups

A focused first version that proves the concept with real users, built in weeks rather than quarters and ready to iterate.

iOS, Android & Cross-Platform

Native builds where performance matters, cross-platform where speed and budget matter, decided during scoping.

UI/UX Design & Prototyping

Interface design, interaction flow and clickable prototypes that are tested before a single production screen is coded.

API & Third-Party Integrations

Payments, ad networks, analytics, CRM and internal systems connected properly, with error states nobody usually plans for.

Business Process Automation

Mobile-first automation of the manual work that currently lives in spreadsheets, group chats and paper forms.

Maintenance, Support & LiveOps

Store policy changes, OS updates, crash response and content updates handled under an agreed reaction time.

Why Studios And Founders Choose Us

A studio that commits to a scope and then delivers it

Three principles that decide how every project runs, from the first estimate to the last support ticket after release.

A Scope You Can Hold Us To

Every project starts with a written scope covering functionality, user journey and technical requirements. It reduces unnecessary development, controls cost and keeps the product from expanding past its original objective.

One Point of Contact

A single project lead, a shared board you can open at any time and a written summary at the end of every sprint. You never have to ask what is happening with your product.

Your Product Stays Yours

Source code, art sources, project files and store accounts belong to you from the first commit. Handover documentation is part of every delivery, not an upsell.

By The Numbers

Results measured after launch, not on the pitch deck

Analytics and event tracking go live with the first build, which means the numbers below come from released products rather than from estimates written before development started.

48+

MVPs Delivered

Integrations Shipped

How We Work

A process built to remove surprises

Every project moves through the same structured path. Scope is agreed in writing before development begins, and each sprint ends with an installable build you can hold in your hand.

Step 01

Discovery Call

A short conversation about the product, the audience and the business problem behind it. No prepared documents required, and no charge for the call.

Step 02

Scoping & Estimate

We define the required functionality, user journey and technical requirements, then return a written estimate with fixed stages, deliverables and timelines.

Step 03

Design & Prototype

User flows and a clickable prototype come before production art. The path through the product is tested and approved while changes are still cheap.

Step 04

Development Sprints

Two-week sprints, each ending with an installable build and a short written summary of what changed, what is next and what needs your decision.

Technology Stack

Chosen for your product, not for our habits

The engine, framework and infrastructure are selected during scoping, and the reasoning is written down so the decision can still be reviewed two years later.

Frequently Asked Questions

Everything worth knowing before we start

The questions we are asked in almost every first conversation, answered without marketing language. If yours is not here, the contact form reaches the same people who would answer it.

It depends entirely on scope, and we will not pretend otherwise. A focused MVP sits in a different bracket than a mid-core game with a live back end. That is why we do not publish price lists: after the discovery call and the scoping session you receive a written estimate with fixed stages and deliverables, prepared for your specific requirements.

A focused MVP is usually eight to twelve weeks. A business application with integrations typically runs three to six months. Casual games with a meta layer are four to nine months, and mid-core titles with servers and live operations run longer. Scoping gives you a realistic schedule before you commit to anything.

Both. A significant share of our work is improving, rebuilding or taking over an existing mobile product. We start with a technical audit and an honest assessment of what is worth keeping, then propose either continuation or a targeted rebuild of the parts that need it.

You do. Source code, project files, design sources and documentation belong to you from the first commit, and store accounts stay in your name. Handover documentation is part of every delivery.

Unity and Godot for games, Flutter and React Native for cross-platform applications, Swift and Kotlin when native is the right call, with Node.js, PostgreSQL, Firebase and AWS behind them. The choice is made during scoping based on your product and roadmap, not on our preferences.

Support agreements cover operating system updates, store policy changes, crash response with an agreed reaction time and a schedule of improvements. For games we also run live operations: events, balancing passes and seasonal content based on real cohort data.

Pricing Built Around Your Scope

We do not publish fixed price lists. Every game, application and MVP has a different scope, platform mix and support model, so every quote is prepared individually after a short scoping conversation. Send us your requirements and you will receive a written estimate with a clear breakdown of stages, deliverables and timelines.

Client Feedback

What teams say after the launch week

Feedback from founders, publishers and operations teams we have worked with. Names are withheld where projects are covered by a non-disclosure agreement.

The scoping session alone was worth it. Half of what we thought we needed for launch turned out to be version two, and the version we shipped was in the stores nine weeks later.

Founder

Service Marketplace Startup

We came with a prototype another team had abandoned. They audited it, told us plainly what was worth keeping, and rebuilt the rest without pretending the audit was free work.

Product Lead

Casual Games Publisher

A build at the end of every sprint and a summary we could actually read. After three agencies, that alone made the project feel manageable.

Operations Director

Multi-Location Service Group

Retention was flat after launch. They ran the cohort data, proposed three changes, and shipped them in two updates. The second one moved the number.

Head of Growth

Mobile Publishing Studio

Our internal tool replaced a spreadsheet forty people were editing at once. The audit trail alone paid for the project inside a year.
