MVP Development for Startups
Founding Developers is a two-person senior engineering studio in Poznań, Poland (EU, CET) that builds MVPs reaching real users in 4–10 weeks. Fixed scope from €1,500 — typical MVPs land between €6,000 and €18,000 — with production-grade software, full IP ownership, and cofounder-level thinking instead of contractor output. No project managers, no junior handoffs.
Scope your MVP with us →What is MVP development?
MVP development is the process of building a minimum viable product — the smallest version of your product that real users can use and pay for — so you can validate demand before investing in a full build. Done well, it's not a throwaway prototype: it's the production foundation your company grows on.
Product discovery first
Before we write code, we understand the problem: who the user is, what they do today, and what the smallest thing is that changes their behavior. We cut scope aggressively — most first versions ship with fewer features than founders expect, and convert better because of it.
Build and launch
We ship working software weekly. Real deployments, real staging environments, real user accounts — not slideware. By mid-project you're already putting the product in front of pilot users while we build the rest.
Measure and iterate
An MVP exists to answer questions. We wire in analytics from day one, watch what users actually do, and iterate on evidence. When the signal says "build more," the codebase is ready to grow — no rewrite needed.
How we build MVPs in weeks, not months
AI-amplified senior engineering
Two senior engineers using AI tooling for the repetitive work outproduce a traditional five-person team — while every architectural decision still comes from 13+ years of production experience. Small team, big output, no coordination tax.
Boring technology that lasts
Elixir/Phoenix, React/Next.js, PostgreSQL — proven stacks your future hires already know. Your MVP shouldn't be a science experiment; it should be the first version of a real company's codebase.
Weekly shippable slices
Every week ends with deployed, clickable software and a short demo. You always know where the project stands, and you can put the product in front of users long before "launch day."
Direct access, no layers
You work directly with Piotr and Kasia — the people writing the code. Decisions that take agencies a week of ticket-routing happen in a same-day conversation.
How much does MVP development cost?
A production-ready MVP costs €6,000–€18,000 with us as a fixed-scope project; smaller scopes start at €1,500, and ongoing support runs €1,600/month for 5 working days at €320/day. What drives the price is scope: the number of user flows, third-party integrations, and compliance requirements — which is why we scope together first and quote a fixed number before any money changes hands.
Fixed-scope MVP
From €1,500 · typical €6,000–€18,000
Defined deliverables and timeline, sprint-based development, regular demos, code handoff with documentation, and post-launch support. Most MVPs go from kickoff to production in 4–10 weeks.
Ongoing support after launch
From €1,600/month — 5 working days at €320/day
We stay embedded after launch: iterating on user feedback, hardening infrastructure, and shipping the next features. Pause or resume anytime — you pay only for the days you need.
Where we build MVPs
We're an EU company based in Poznań, Poland (CET), working with startups worldwide. For Nordic founders we've put together dedicated pages covering pricing in local currency, contracting, and how collaboration works in practice.
MVP development in Denmark
Copenhagen and Poznań share the same timezone, and the krone's euro peg means our EUR pricing is effectively fixed in DKK. EU contracts, GDPR by default.
MVP development for Danish startups →MVP development in Sweden
We helped rebuild the e-commerce frontend of Stockholm's Fishbrain — 13M+ users. Same CET timezone, English-first collaboration, EU contracts.
MVP development for Swedish startups →Proof, not promises
We took Towar, our own AI agent platform, from first commit to live users in 2.5 months with two engineers — and we helped relaunch Fishbrain's e-commerce frontend for 13M+ users in 3 months. Work can start within 5 working days of the first conversation.
Case study: an AI platform MVP in 2.5 months
Towar.ai is a production AI agent orchestration platform — agent builder, scheduled autonomous runs, persistent memory, full debugging, and an MCP server. We built it entirely in Elixir and Phoenix: from first commit to live users in 2.5 months, with two developers, 349 merged PRs, and no JavaScript framework.
That's the same playbook we apply to client MVPs: ruthless scoping, boring technology, weekly shipping, and production quality from the first deploy.

How much does it cost to build an MVP?
A typical MVP we build costs €6,000–€18,000 as a fixed-scope project; smaller scopes start at €1,500. The price depends on the number of user-facing flows, integrations, and compliance requirements. You get a fixed quote before we start — no hourly surprises.
How long does it take to build an MVP?
Most MVPs we build take 4–10 weeks from kickoff to production. We shipped Towar, a full AI agent platform, in 2.5 months with two engineers. We ship working software every week, so you see real progress from the first sprint.
What technology stack do you use for MVPs?
Elixir and Phoenix for real-time and AI-heavy products, React or Next.js when a JavaScript stack fits better, and PostgreSQL for data. We choose proven technology your future team can hire for — no experimental frameworks you'll regret in a year.
Who owns the code and IP of the MVP?
You do. Full IP transfer is standard in our contracts — code, documentation, and infrastructure configuration. Everything lives in your repositories and your accounts from day one.
What happens after the MVP launches?
Three options: continue with Ongoing Support from €1,600/month (5 working days), pause and resume when needed, or take the codebase to an in-house team — we document everything and hand off cleanly. Many clients keep us for iteration after launch.
