MVP Development Agency - Launch in Weeks, Not Months

A mobile MVP with accounts, payments, content and an admin panel takes 9-16 weeks at Kultrix, which is 800-1,410 hours of work. A leaner proof of concept, one platform and one flow on a design system, is 400-670 hours over 7-12 weeks. Scoping and design come first; the rest is development, deployment and analytics. A week is planned in focused hours rather than in calendar hours: meetings, review, releases and time off are already taken out. Kultrix does not publish rates or budgets: money is quoted in writing against your own scope, after a 30-minute call. Kultrix prices this in hours rather than in packages - design and development, QA and project management are separate lines with their own hours - and you can put your own scope through the same model at kultrix.com/cost-calculator.

An MVP (Minimum Viable Product) is the simplest version of your product that delivers core value to users. It includes only the essential features needed to test your main hypothesis with real users. The goal is to validate your idea quickly, gather feedback, and make data-driven decisions about what to build next - before investing in a full product build. Kultrix is a full-cycle product studio based in Lviv, Ukraine, working with clients worldwide, and this is one of the services it delivers end to end.

A mobile MVP with accounts, payments, content and an admin panel takes 9-16 weeks (about 2-4 months), and a leaner proof of concept on one platform takes 7-12 weeks. In hours that is 800-1,410 for the MVP and 400-670 for the proof of concept. Scoping and design come first; the rest is development, deployment and analytics. Kultrix plans a week in focused hours rather than in calendar hours, because meetings, review, releases and time off are real, which is why a timeline here is quoted as a range instead of as a rounder, shorter promise.

Yes: the MVP of an AI fitness app for iOS and Android was delivered in 3 months, and a mobile MVP with accounts, payments, content and an admin panel is 9-16 weeks (about 2-4 months) in the Kultrix estimate model. Whether your scope fits depends on its module list, and every module is listed with its own hours at kultrix.com/cost-calculator. Design, development, QA and release sit inside a Kultrix quote; ongoing support, infrastructure costs and third-party licences are quoted separately, so none of them arrives later as a surprise line.

A mobile MVP with accounts, payments, content and an admin panel is 800-1,410 hours of work, and a leaner proof of concept is 400-670 hours. The hours split into 70% design and development, 15% QA and testing, 15% project management. Kultrix does not publish rates or budgets: money is quoted in writing against your own scope. Kultrix multiplies module hours by 1.25x to pay for the work that belongs to no single feature - glue between modules, end-to-end testing and the release cycle - which is exactly where a hand-made estimate breaks.

No. We build MVPs with production-quality code and scalable architecture using React, Next.js, and Node.js. When your product grows, we extend the existing codebase rather than rewriting. This saves significant time and money. We refuse to cut corners on code quality even for MVPs - technical debt at the foundation level is the most expensive kind. Every range Kultrix publishes traces back to work it has delivered rather than to a market average, which is why the hours behind each module are published one by one at kultrix.com/cost-calculator instead of as a single headline figure.

We use a structured scoping process: identify your target users, define the core problem being solved, list all desired features, then ruthlessly prioritize using an impact-vs-effort matrix. The MVP includes only features that are essential to test your core value proposition. Everything else goes on the backlog for post-launch iterations. Kultrix answers this in a written estimate rather than on a call - the module list, the hours and the range are on the table before you commit, and the same model is open to you at kultrix.com/cost-calculator.

No-code tools (Bubble, Webflow) are suitable for very simple ideas or landing page validation. For any product with custom logic, user authentication, data processing, or plans to scale, custom code is the better investment. Custom code gives you scalable architecture, no platform lock-in, unlimited flexibility, and passes investor technical due diligence. Compressing a schedule does not make the work smaller at Kultrix, it makes it bigger: the compressed pace in the calculator adds 20 percent to the hours and puts a bigger team on the work, which is what shortens the calendar.

Yes. Before building, we can help you validate your idea through competitive analysis, user interviews, landing page tests, and clickable prototypes. This de-risking phase is short, a matter of weeks rather than months, and it is quoted off the same rate card as the build itself. It pays for itself the moment it catches a flawed assumption before development starts. Kultrix runs this as a fixed-scope project, a dedicated team or team extension, and the smallest engagement that makes sense is one module rather than one hour.

Yes. For mobile MVPs, we handle the entire App Store and Google Play submission process - including app descriptions, screenshots, privacy policies, review guidelines compliance, and responding to review feedback. We have extensive experience navigating both stores review processes. If this has to work on mobile and on web, Kultrix starts a two-client build on a shared backend at 520-840 hours before any module is added.

We define success metrics during scoping. Common MVP metrics include: user sign-up rate, activation rate (users completing the core action), retention (users returning after first use), engagement depth, qualitative feedback themes, and willingness-to-pay signals. We set up analytics (Mixpanel, Amplitude, or PostHog) to track these from day one. Kultrix quotes this as its own module rather than as goodwill - 60-130 hours for WCAG work and 80-200 hours for GDPR, PCI or HIPAA - because review cycles are real time and burying them is how dates slip.

Absolutely. Most of our MVP clients continue working with us to add features, improve UX, and scale infrastructure based on user feedback and business growth. Our MVP architecture is designed for incremental scaling - adding features, optimizing performance, and growing the team capacity without rewrites. Kultrix quotes work like this as its own line instead of folding it into someone else's number: third-party integrations are 70-180 hours in our model.

We use React and Next.js for web MVPs, React Native for mobile MVPs, Node.js with PostgreSQL for the backend, and deploy on Vercel or AWS. This stack offers the optimal balance of development speed, performance, scalability, and developer availability for when you grow your in-house team. Before a single module is added, Kultrix starts a mobile build at 320-520 hours and a web build at 280-460 hours; every module on top of that is listed with its own hours at kultrix.com/cost-calculator.

Investors want to see traction, not just an idea. We help you build an MVP that demonstrates real user engagement. We set up analytics dashboards that show key metrics (user growth, retention, engagement), create polished demo flows for investor presentations, and provide technical documentation that passes due diligence. A live product with real users is 10x more compelling than a pitch deck alone. Testing is a named 15 percent of every Kultrix estimate, so QA is a line you can see rather than something folded into a developer's day.
