CAPABILITY

One contract covers four practices. Whatever the project needs stays inside the number we quoted — no separate vendor, no separate invoice.

01

WEB PLATFORMS

Products, portals and internal tools built to carry real production traffic, not demos.

02

MOBILE

Native and cross-platform apps, built for both app stores under the same fixed price.

03

GAMES & REAL-TIME

Unity engine work, multiplayer backends and simulation — built to hold up under real concurrent load.

SYSTEMS & DATA

Integrations, migrations and the plumbing nobody wants to estimate — quoted the same way as everything else: once.

HOW THE PRICE IS FIXED

Two weeks from first call to a signed number. The discovery is paid work — its cost comes off the final invoice.
01

DIAGNOSTIC

Partners only. Ninety minutes on the actual problem, not a sales script.

02

SCOPE LOCK

Every screen, endpoint and acceptance test, written down and signed before a line of code ships.

03

ONE QUOTE

One number, one date. If we misjudged the size of the job, that's on us — not on your invoice.

04

BUILD & HANDOVER

Demos every two weeks. Source code and infrastructure access, handed over the day we're done.

HOW WE WORK

Fixed scope isn't a black box. Every project runs the same way: meetings only when there's a decision to make, one board the client can check any time, and code that ships reviewed and versioned from commit one.

Meetings with an agenda

We get on a call when there's a real decision on the table. Everything else is written down, async.

One board

Scope, tasks and dates live in one place the client can open any time — no shadow spreadsheet, no "let me check with the team."

Shipped, versioned

Every line ships reviewed and traceable. Approval happens in the pull request, not over WhatsApp.

TELL US WHAT HAS TO EXIST.

One call tells you whether we're the right studio and roughly what it costs — no proposal deck, no follow-up sequence. We take four projects a quarter, so we say no more often than we say yes.
