Your external engineering team for studios and startups. Games, QA, software — delivered by engineers who've shipped across the stack.
Some companies are built from business plans. Kivibyte was built from conviction.
We're Denny and Nat — a developer and a quality specialist based in Tallinn, Estonia. We iterate fast, we fail honestly, and we never hand off something we wouldn't stand behind.
Between us we bring game development expertise, systems thinking honed across years in logistics and QA, and a combined obsession with finding what's wrong before it becomes your problem.
We're a small studio and we're proud of that. You'll always know who's working on your project. You'll always be able to reach us. And you'll always get work held to a standard that larger operations simply don't have the care or attention to match.
Unreal. C++. Shipped. Gameplay, systems, tooling — across the stack.
We find what your team missed. Then we find what we missed. Then we ship.
Built to spec. Handed over clean. Still working a year later.
Technical Lead // Co-founder
Senior maker of games.
14 years building games across indie, AA, and AAA. Full-stack across gameplay, systems, and tooling — Mortal Shell shipped to over a million players and earned a nomination for Best Newcomer at The Game Awards.
Most recently Technical Manager at Mr.Kite / Youmio.ai, an AI-first studio — keeping him at the exact edge where games and intelligent systems meet.
Director of Quality & Operations // Co-founder
Your customers won't see her work. But they'll feel it.
Nat finds the bugs nobody else finds. A decade across logistics, QA, and operations — building tools to fix inefficiencies, optimising systems, and leading a major platform transition at a national rail freight company.
She's worked across complex, high-stakes systems where mistakes have real consequences. Precise by nature. Relentless by habit.
