testimonials
Read what our clients say about partnering with us for successful design and development.
What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.
Frank W.
Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.
Dinant V.
Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.
Timur G.
Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.
Musa S.
Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.
Taj S.
We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.
Laurent D.
Kultrix developed our mobile app and the entire backend infrastructure. They took ownership of the architecture decisions early on, which saved us months of rework. The app runs smoothly and our users love the experience.
Taras L.
We have been working with Kultrix for years now, from software development to ongoing design work. They consistently deliver quality and understand our product deeply. It feels like an extension of our own team rather than an external partner.

FAQ
Absolutely. Most of our clients come to us with a concept, not a spec. We run a discovery phase where we help you define the scope, features, and user flows. You focus on the business vision, we handle the technical side from day one. You can describe the idea in your own words at kultrix.com/contact.
It depends on scope, so we publish the rate and the hours behind it instead of one number. Ongoing support, infrastructure and third-party licences are quoted separately, and the module-by-module breakdown for your own scope is at kultrix.com/cost-calculator.
A mobile MVP runs 9-16 weeks, a web SaaS with integrations and a second language 9-17 weeks, and a full platform across mobile and web 20-40 weeks. You see working builds every two weeks, not one reveal at the end. The week count for your own scope comes out of the first call, which you ask for at kultrix.com/contact.
Kultrix is a product team in Lviv, Ukraine, building web and mobile products for clients worldwide.
Yes, 100%. Once the project is paid for, you own everything: source code, designs, assets, accounts. No lock-in, no licensing fees. You can take it to any developer if you ever want to.
Yes. If you have Figma files or a prototype ready, we can skip the design phase and go straight to development. We will review the designs for technical feasibility and flag anything that might cause issues on real devices. Send the Figma link at kultrix.com/contact and the feasibility review comes back before anything is agreed.
It happens on every project and we plan for it. We work in 2-week sprints, so you can reprioritize features at the start of each sprint. Major scope changes may affect timeline and budget, but we will always discuss that transparently before proceeding.
Yes. We specialize in React Native, which lets us build one codebase that runs natively on both platforms. You get the quality of a native app without paying to build it twice.
Just your idea and 30 minutes for a call. We will walk through your concept, ask the right questions, and follow up with a rough scope and estimate within a few days. No payment, no commitment at that stage. You ask for that call at kultrix.com/contact.
