(Custom software, bought like a product)
Delivered as agreed. Under warranty.
We agree the acceptance checks with you before writing a line of code, build at a fixed price with working software every week, and back it all with a 12-month warranty: bugs we ship are fixed free. If a milestone doesn't pass its checks, you don't pay for that milestone.
From first call to working software in weeks, not quarters.

Process
(How we work · no surprises)
Scope & Fixed Quote
We spend 1-2 weeks understanding your business and writing the scope document: what gets built, the acceptance checks for every milestone, a fixed price, and a timeline - before any code is written. If the plan doesn't convince you, it's yours to take anywhere.
The Build
Development runs in weekly milestones against the fixed scope and price set in your scope document. Every milestone has acceptance checks agreed before we build: you watch them pass, or you don't pay for that milestone. Every week you see working software, not slide decks.
Ship & Support
We take the product live and stay on through the launch window. Then you choose: the Care Plan, where we host, monitor, and maintain everything for a monthly fee and your warranty never expires - or a full handoff to your team with documentation and everything they need to take over. No lock-in, ever.
Pricing
(One ladder, three small yeses)
Scope & Fixed Quote
€1,000-€5,000
1-2 weeks · scales with the size of the build
The plan before any code: for a new product, or a review of the one you already have - including AI-built prototypes that never made it to production. You get a scope document with acceptance checks per milestone, a fixed price, and a timeline. If it doesn't convince you, it's yours to take anywhere.
The Build
€5,000-€30,000
2-4 weeks · larger builds quoted individually
The complete product at the fixed price from your scope document: a website, a web app, a mobile app, or all three. Delivered in weekly milestones - each one passes its agreed acceptance checks or you don't pay for that milestone. Every build carries a 12-month warranty: bugs in what we built, fixed free. And you own all of it - the code, the design, the product.
Care Plan
From €250/month
Cancel with a month's notice
After launch, we run it: hosting, monitoring, backups, updates, small changes, and bug fixes on one monthly bill. While you're on the plan, your warranty never expires. If you ever leave, everything is handed over - code, data, infrastructure, documentation.
A written warranty, on every build.
If something we built stops passing its agreed acceptance checks, we fix it free for 12 months after delivery.
On the Care Plan, it never expires.
Beliefs
(Strong opinions, in writing)
Software should come with a warranty.
Acceptance checks are agreed with you before we build, for every milestone. A milestone passes them or you don't pay for that milestone, and bugs in what we built are fixed free for 12 months after delivery.
Fixed price is a discipline.
The price you sign is the price you pay. If we underestimate the work, that's our problem, not yours.
Scoping should be paid.
Real work with a real deliverable: the scope document your build's warranty is measured against. The plan is yours, either way.
Same team scopes and ships.
The people who scope your product are the people who build it. The studio is small by design. There's no handoff between sales and delivery.
No lock-in is a feature.
Your scope document is yours after scoping. Your code is yours after launch. We win the next project because you want us back, not because leaving is expensive.
Working code, not slides.
Every week, you get a working build to click through. Problems surface while we can still fix them. No status reports. No surprises at the end.
About
(The studio)
We are a product engineering studio based in Slovakia, building software for founders without an engineering team.
Kristián Müller
Founder · LinkedIn
I've spent the last several years building products for startups and scaleups across Europe and the US: data platforms, marketplaces, mobile apps, taking them from early concepts through production at scale.
Why can a small studio offer a warranty at all? Verification. Every build runs through automated checks and the acceptance criteria you signed off on before it reaches you. That discipline is what makes a fixed price, a weekly working build, and a written warranty possible.
