MVP development for startups
Your idea doesn't need a year of development to be tested. It needs the smallest version that proves someone will pay for it.
From 4,000 USD
Example: a product we built and run, as it is.
01 The problem
Why most first products fail
The most common founder mistake isn't technical: it's building the full featured product before confirming anyone wants it. Months and the whole budget go into features nobody could do without, then launch day reveals the market wanted something else entirely.
We work the other way round: we sit with you and cut the idea down to the smallest version that tests the core hypothesis, build it on foundations that survive success, and put it in front of real users within weeks. Everything you spend after that goes into what the market has proven it wants.
02 What you get
What MVP development includes
A scoping workshop
We separate the essential from the nice to have: you leave with a clear list of what goes into the first version and why, and what waits without regret.
A launchable product, not a demo
A version real users sign up for and pay in: sign in, payments if needed, and the complete experience of the core hypothesis.
Foundations that survive success
The same stack we build large systems on, so if the idea takes off, you build on top of it instead of rewriting from scratch.
Measurement from day one
Built in analytics that show what users actually do, so your next decisions run on data, not impressions.
Full ownership
The code is yours on payment, which matters when investors run due diligence on everything you have.
A fit if you are
- A founder validating an idea before a funding round
- An established company launching a new digital product
- An idea owner who needs a technical partner, not a contractor waiting for specs

Questions about MVP development
How much does MVP development cost?
From $4,000 depending on the idea's scope, and you'll find the price in your currency in the price section above. The first workshop is free: we discuss your idea and give you a realistic read on scope, cost and timeline before any commitment.
How fast can we launch?
The target is always weeks, not months, and tight scoping is what makes that possible. The exact timeline depends on the idea and is fixed in the proposal.
Will you sign an NDA?
Yes, without hesitation, your idea stays yours. But what protects a startup idea best is shipping speed, not secrecy, and speed is what we work for.
What if the MVP works and we need to scale?
That's the goal: the foundations are built to take growth. We can keep developing with you, or hand the code to your in house team when you build one. No lock in either way.
