A
On-site Berlin vendor
A GmbH, a Mitte address, German workshops. Right when procurement requires it. We are not that vendor. We will not rent a mailbox to look like it.
Berlin / DACH
A custom software agency for Berlin product teams
Berlin teams searching for a custom software agency usually want English (or German-friendly) communication, EU working hours, and engineers who have shipped — not a slide deck about culture. CodeLoop Studio is a Sarajevo software studio. We build mobile apps and custom software for European companies, including teams in Berlin, remotely. Same CET band. No rented Mitte mailbox.
For Berlin teams. Not a custom software agency in Mitte.
Berlin teams searching for a custom software agency usually want English (or German-friendly) communication, EU working hours, and engineers who have shipped — not a slide about culture. A custom software agency for Berlin product teams is CodeLoop Studio in Sarajevo. We build mobile apps and custom software for European companies, including teams in Berlin, remotely. Same CET band. No rented Mitte mailbox.
Bosnia and Berlin share Central European Time. Kickoff, refinement, and demos happen in the working day. We will not pretend a coworking photo is an office. If procurement requires a German GmbH on-site in Berlin, we are the wrong vendor — we say that on this page so nobody is surprised. If you need a squad that ships and overlaps your hours, we are a fit. Cost is typically below a local Berlin senior pod; the hours match.
The general offer is custom software development. Mobile-only briefs sit on custom mobile app development. Delivery and stand-ups are in English. We implement German UI copy from your translations. Native languages on the team are Bosnian and Croatian. If every workshop must be in German, we are probably not the fit.
CET engineers, GDPR named, no rented Mitte photo
A senior product squad for mobile apps, admin tools, and the software in between — one studio, English delivery, CET stand-ups that are live rather than a 9pm Zoom. We implement German UI copy from your translations. Bosnian and Croatian are native on our side. Fixed-scope builds or dedicated engineers in your process. We can review a German MSA. Practical delivery is remote. Legal fit depends on the contract — we will not bluff.
GDPR and data handling are discussed before the DPA lands, not after. Data flows, processors, where the app lives. EU hosting is normal when the brief requires it. Typical product work is three to nine months; a thin MVP can be shorter when the slice is honest. After launch we can stay on the backlog or hand over. Code and Figma stay in your tools. You keep product ownership.
This fits Berlin startups and DACH product orgs that already hire remotely across the EU, and teams that need delivery ownership rather than a body shop. Cost is typically below a local Berlin senior pod; the hours match. Koliko is a beverage inventory app around Bluetooth scales — custom software with a hardware edge, European ops, real devices. That is the delivery bar. We do not invent a roster of unnamed German logos. We do not pretend a coworking photo is an office. If you need a GmbH on-site in Berlin, stop here.
What DACH product orgs actually buy from Sarajevo
CET stand-ups that are live
Not a 9pm Zoom. Code and Figma stay in your tools. Written status you can forward internally.
Mobile and the admin behind it
One studio. Apps, portals, internal tools. Fixed-scope builds or dedicated engineers in your process.
GDPR before the DPA
Data flows, processors, where the app lives. EU hosting is normal when the brief requires it. We will not treat the DPA as a week-twelve attachment.
German UI, English delivery
We implement your translations. Workshops in English. Say so if that is a blocker.
German MSA, reviewed honestly
We can review your paper. Practical delivery is remote. Legal fit depends on the contract — we will not bluff.
Hardware-shaped software
Koliko is inventory on a scale. That is the delivery bar: ops people open on a shift, not a brochure site.
Local Berlin pod versus this studio
B
Sarajevo, same clock
CET overlap, English delivery, typically lower cost at the same seniority. You keep product ownership. We own delivery quality. Most Berlin teams already hire remotely across the EU.
Case study
Koliko
A beverage inventory app around Bluetooth scales and reporting bars can act on — custom software with a hardware edge, not a brochure. European ops, real devices.
Before you copy a Berlin street into the RFP
Are you located in Berlin?
No. Sarajevo, CET. That is usually an advantage for hours and cost. FAQ on this page says the same.
Typical calendar
Product work three to nine months; a thin MVP shorter when the slice is honest. Estimate within 24 hours via the online estimate.
Must every workshop be German?
If yes, we are probably not the fit. If English delivery plus German UI is enough, send the brief.

Koliko case study
Stop guessing what’s left in the bottle. Weigh it. Koliko uses Bluetooth scales to measure beverage volumes and support real-time inventory workflows for drink stores, cafés, and service teams.
Custom software agency
Off-the-shelf software stops at your actual process. We are a custom software development agency: MVPs, client portals, internal tools, and AI features that sit inside a real product — built by a studio in Sarajevo that works in English with US and European teams. This is systems work, not a marketing homepage and not a single-platform mobile sprint.
Custom mobile apps
You need a custom mobile app that can pass App Store and Google Play review, survive the next OS release, and get used more than once. CodeLoop Studio designs and builds native and cross-platform apps for startups and companies that want a product team, not a pile of screenshots. Stack choice comes after we see the product — this page is how we engage, staff, and ship.
Custom software for Berlin teams (blog)
Berlin product teams want English delivery and EU hours. We share CET from Sarajevo. We will not photograph a coworking space as an office.
Web development · Sarajevo
CodeLoop Studio does web development in Sarajevo: marketing sites, booking flows, and product pages that load on a phone and convert. We write in English and Bosnian. Buyers are often in the US, UK, and EU; the named team sits on Dobrinja. This is the website brief — not an app-store binary, and not a logged-in dashboard.
Ecommerce
If the cart dies on mobile, the theme was free and the revenue is not. We build ecommerce websites around catalog reality: variants, shipping, taxes, and a checkout people finish. The storefront is a sales channel with ops behind it — not a marketing microsite with a Buy button taped on.
New York
If you searched for a studio to make a custom mobile app in New York, you do not need another vendor with a Manhattan coworking photo. You need a team that ships iOS and Android, speaks product English, and shows up on an ET morning call. CodeLoop Studio is based in Sarajevo and works with US companies remotely — including product teams in New York. No Fifth Avenue address. Overlap hours and store-ready delivery instead.
