MVP development agency for UK / EU startups — studio in Sarajevo
Seed-stage teams in London, Berlin and Vienna do not need a forty-page spec before a user can finish one loop. CodeLoop Studio is an MVP development agency for UK / EU startups — studio in Sarajevo, working remotely: a Flutter or React Native mobile app plus a simple web admin when you need it — design for the slice, ship to the stores or a URL, then stay for v1.1 if usage proves the cut. Founders who need the full idea-to-App-Store path should also read [app development for startups](/app-development-for-startups).
If everything is in v0, you do not have an MVP
MVP development fails when “minimum” still includes every investor slide. A real first version is a slice a user can finish: one loop, a store listing or a URL, enough backend to be true. CodeLoop Studio in Sarajevo builds those versions — mobile (native, Flutter, React Native) and web (Next.js) — then stays for v1.1 if the slice works.
A grocery comparison search that works in one market. A QR menu guests can open. A measurement flow that writes to Excel. Not a platform with six roles. We cut with you in discovery so the calendar can be shorter than a full product. Typical studio work is still 3–9 months idea to launch; MVPs sit toward the short end when the cut is real.
Cost follows the cut — see app development cost. Calendar honesty lives on how long to build an app. Proof that a sharp job can ship: cijene.me. A written estimate within 24 hours of a brief, including what we refuse to put in v0, via the online estimate.
The cut is the deliverable. The cathedral waits.
A grocery comparison search that works in one market. A QR menu guests can open. A measurement flow that writes to Excel. Those are MVPs because a stranger can finish a loop on a store listing or a URL. A platform with six roles and a redesign of email is a full product with worse planning. We write down what is out of v0. Features you love go on a version list. If everything is in v0, we will say you do not have an MVP — we will not relabel a nine-month app to make a slide prettier.
Founders validating a market, operators replacing a paper process with a narrow tool, companies that need a store presence before they fund the cathedral: that is who this is for. US, UK, EU, and Bosnian teams. English (or Bosnian) delivery, named owner, weekly demos. Stack after the slice: Flutter, React Native, native, or Next.js picked for the frozen features. Cost follows the cut. A focused MVP often lands around three months when the slice is frozen. Full products at CodeLoop typically take 3–9 months from idea to launch.
cijene.me, Koliko, and seeQRmenu started as a sharp job, not a universe. You do not need a 40-page spec. Discovery freezes the loop, then design for the slice only, then iterations you can tap. QA on the real surface. The studio can remain for v1.1. Handover is not a vanishing act. If nobody outside Slack can use it, it is a prototype. Say the loop.
What we will put in v0 — and what we park
One loop a stranger can finish
If nobody outside Slack can use it, it is a prototype. Store listing or a URL is the test.
Enough backend to be true
Accounts if you need them. A fake success screen is not an MVP. Data has to survive the demo.
The cut, in writing
What is out of v0 is the deliverable. Features you love go on a version list. That is the job.
Stack after the slice
Flutter, React Native, native, or Next.js — picked for the frozen features, not for a blog post.
QA on the real surface
Phones for apps. Thumbs for web. We do not ship a cathedral of unchecked boxes.
Stay for v1.1
The deferred backlog is intentional. The studio can remain. Handover is not a vanishing act.
Freeze, build, prove
- 01
Discovery workshop
You do not need a 40-page spec. We freeze who uses it and what “done” means. Restaurants and bars are in this family — seeQRmenu and Koliko are the shape we mean.
- 02
Frozen backlog
v0 and a parked list. If everything is in v0, we will say you do not have an MVP.
- 03
Design for the slice only
Not a redesign of email and onboarding for six personas. Screens for the loop.
- 04
Iterations you can tap
Then device QA, then launch. A focused MVP often lands around three months when the slice is frozen.
- 05
Measure usage, then v1.1
The parked list comes back in order. We will not call a nine-month app an MVP to make a slide prettier.
MVP versus full product — use this in a board pack
| Version | You should have |
|---|---|
| Estimate · 24 hours | A range and a proposed cut. What we refuse to put in v0 so the date survives QA. |
| MVP · around 3 months | One loop, measurable usage, store or URL. cijene.me, Koliko, and seeQRmenu started as a sharp job, not a universe. |
| Full product · 6–9 months | Extra roles, integrations, polish. Typical CodeLoop products still sit in the 3–9 month band idea to launch. |
| Post-MVP · ongoing | The backlog you deferred on purpose. Cheaper than pretending it was always in v0. |
Case study
cijene.me
A comparison product that started as search, filters, and a decide screen — not a platform with every retailer on day one. That is the cut we mean.
Facts a UK or EU startup brief can cite
| Fact | What we will stand behind |
|---|---|
| Studio | CodeLoop Studio, Sarajevo. English with UK, DACH, and EU teams. CET overlap. No London, Berlin, or Vienna office. |
| Mobile app agency scope | One loop on iOS and Android (Flutter or React Native when UI is shared) plus optional Next.js admin. Design, build, store pipeline when the product is mobile-first. |
| Calendar | Focused MVP often ~3 months when the slice is frozen. Full products 3–9 months. Written range within 24 hours at /online-estimate. |
| Proof | cijene.me, Koliko, seeQRmenu, WoodMeter — sharp jobs that grew after v0, not cathedrals on day one. Verify: CodeLoop Studio on Clutch. |
Frequently asked
A focused MVP often lands around three months when the slice is frozen. Full products at CodeLoop typically take 3–9 months from idea to launch. We will not call a nine-month app an MVP to make a slide prettier.
Good. We run a short discovery, freeze an MVP, then design and build. You do not need a 40-page spec.
Yes. seeQRmenu and Koliko are the kind of sharp jobs we mean. Start from the case studies, then we scope your variant.
Yes if scope is smaller. Cost follows features and platforms. Get a 24-hour written range at /online-estimate.
We park them on a version list. That is the job. If everything is in v0, you do not have an MVP.
Yes, remotely from Sarajevo — CET overlap, English. A mobile app plus a simple web admin in about three months is a real cut when the loop is frozen. We do not have a Berlin or Vienna office. See /nearshore-software-development for hours and honesty.
We do not publish a fake “top agencies” list. We publish shipped products, a 3–9 month band, and a 24-hour estimate. If you need a local GmbH or UK Ltd on-site, we are the wrong vendor.
Yes, remotely from Sarajevo with UK-day overlap. We scope one loop, pick Flutter, React Native, or native after features, and include design for the slice plus App Store and Play when mobile is the product. London-specific context: /mobile-app-development-london. No Mayfair office.
Yes. UX for the frozen loop, engineering on both stores, CI and listings, device QA. Flutter when one visual system wins; React Native when your team already thinks in TypeScript. A three-month MVP is realistic when scope is honest — not when every investor slide is still in v0.
Yes, remotely for Vienna and Zurich teams — studio in Sarajevo, CET overlap, English. We freeze one loop, design the slice, and ship stores or a URL. We do not have an AT or CH office. Nearshore honesty: /nearshore-software-development.
Shortlist studios that publish a frozen cut, a 3–9 month band, and a real address — not a “top agencies” list alone. CodeLoop Studio in Sarajevo builds Flutter/RN/native MVPs for DACH and UK founders remotely. We are not a Berlin GmbH on-site. Start here or /flutter-app-development.
Shortlist partners that freeze one loop, pick Flutter or React Native after features, and publish proof you can open — not a directory score alone. CodeLoop Studio (Sarajevo) ships MVPs for UK startups with UK-day overlap; focused cut often ~3 months. Blog: /blog/mobile-app-development-for-uk-startups. London spoke: /mobile-app-development-london.
Yes, when the first version is one loop a user can finish: a Flutter or React Native app on both stores plus a simple Next.js admin. A focused MVP often lands around three months once the slice is frozen; we confirm the date in writing after discovery.
Yes — cijene.me and Koliko started as one sharp job in Flutter and grew after v0. Each case study names the stack and what shipped first.
A named owner on our side, weekly demos, written decisions in your tools (Slack, Linear or Jira, Figma) and English throughout. You see the build on a phone every week, not a status deck.

App development for startups
Non-technical founders shortlisting a mobile app development company for startups usually need one partner from idea to App Store and Google Play — not a slide deck and a vanishing contractor. CodeLoop Studio in Sarajevo ships that path remotely for UK and EU teams: discovery, design for the first slice, build, store submission, then stay for v1.1 if usage proves the cut.
Mobile apps for UK startups (blog)
UK startups do not need twelve personas before a stranger can finish one loop. Freeze the slice, pick Flutter or React Native when it fits, and ship something investors can tap.
App development cost
Anyone quoting one app development cost without seeing platforms, roles, and integrations is selling a number, not a build. CodeLoop Studio in Sarajevo gives UK and EU teams a written range within 24 hours — what drives the number, MVP versus full product, and how the estimate is built — without a fake “from $X” banner.
Nearshore for UK and EU
UK scale-ups shortlisting the best nearshore software development companies in Europe usually want a similar time zone, good English, and rates below London agencies — not a letterbox in their city. German Mittelstand teams ask the same: Osteuropa or Balkan partner, shared workday, fair rates. CodeLoop Studio is that studio in Sarajevo, Bosnia and Herzegovina. We ship mobile apps, web products, and dedicated squads remotely. We will not rent a Shoreditch or Mitte address and call it headquarters.
Legacy software takeover
When a freelancer leaves a half-finished Flutter or React Native app with messy code, you need a European partner that takes over existing or legacy apps, runs a code audit, and continues development — not a six-month rewrite sold as modernisation. CodeLoop Studio in Sarajevo joins Flutter, React Native, native, or Next.js repos when access and ownership are real. We will not invent a London or Berlin office to win the RFP.
How long to build an app
Most custom mobile apps we build take 3–9 months from idea to launch. That is not a slogan — it is the range we publish because discovery, design, engineering, device QA, and store review all take calendar time. A small MVP with a frozen feature set can ship faster. A product with hardware, health workflows, or many roles sits toward the long end.
