CASE STUDIES
Testimonials
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.
Co-CEO
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.
Co-CEO
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.
CEO, Ping Proxies
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.
CEO, Volume Apps
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.
Product Lead, Pelago
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.

FAQ
We provide end-to-end digital product services including UI/UX design, web development, and mobile app development. From initial concept and prototyping to launch and ongoing support, we handle every stage of the product lifecycle.
The module list decides, so we answer in scopes rather than averages. A first version with accounts and one core feature is 9-15 weeks. An MVP with accounts, payments, content and an admin panel is 9-16 weeks as a mobile app and 10-19 weeks as a web app. A product with the full module list on mobile and web together, from chat and video to AI, offline mode and compliance, is 20-40 weeks. These weeks come out of the hours, at 18 focused hours per person per week, so the calendar moves with the size of the team, not with the deadline. We put dates in writing after discovery, when the module list is fixed. Time your own scope module by module at kultrix.com/cost-calculator.
We follow an agile approach: discovery and planning, UI/UX design, iterative development with regular demos, QA testing, and launch. You get full visibility at every stage with weekly updates and access to project management tools.
It depends on scope, so we publish the rate and the hours behind it instead of one number. Design and development is $35 per hour. QA and testing and project management are $20 per hour each. Across a full team that blends to $30.50 per hour, because every project splits 70% design and development, 15% QA and 15% project management. A mobile MVP with accounts, payments, content and an admin panel is 800-1,410 hours, which is $24,000-$43,000 at that blended rate. We build from Lviv, Ukraine, and the rate covers the whole team, not one contractor. Price your own module list at kultrix.com/cost-calculator. Next step is a 30-minute call, then a written scope with hours, a timeline and a budget range. No payment and no commitment at that stage.
Yes. We offer ongoing maintenance, performance monitoring, and iterative improvements after launch. Our team stays available to handle bug fixes, feature updates, and scaling as your product grows.
