Frequently asked questions

Questions? We have answers

How long does it take to build a web application?

It depends on complexity. A simple MVP takes 6-8 weeks, a full SaaS platform 3-6 months. We work in 2-week sprints, so a working prototype is ready after the first few weeks.

How much does a web application cost?

Projects start from around 4,000-5,000 EUR for an MVP. A full platform is typically 10,000-30,000 EUR. Each project is quoted individually after requirements analysis. Free consultation and quote within 48h.

What technologies do you use?

Frontend: React, Next.js, TypeScript. Backend: Node.js, Python, PostgreSQL. Infrastructure: AWS, Docker, CI/CD. The stack is chosen based on the project, not forced.

What does the collaboration process look like?

We start with Discovery (requirements analysis), then UX/UI design, iterative Agile development with regular demos every 2 weeks, deployment, and support. You have constant contact with the team via Slack/Teams.

Do you provide support after deployment?

Yes. SLA agreements with guaranteed response times, 24/7 monitoring, regular security updates, and development of new features.
