How we work
Services / Software development
We build software for enterprise teams across Sweden, the Nordics, and broader Europe.
Manufacturing, logistics, finance, healthcare, B2B platforms, and the systems running underneath them.

THE PROBLEM
You hand an agency a spec. They build to the spec. Six months later, the software does exactly what you asked for, and it still doesn’t solve the problem.
This happens because most pain owners hire agencies to execute, not to think. The discovery phase is a formality. The questions are about features, not outcomes. Nobody asks why you’re building what you’re building, so nobody catches the assumption that turns out to be wrong.
We’ve seen it from both sides. We’ve rebuilt software for companies that paid another agency to build the first version. We’ve also built our own products, which means we’ve felt the cost of building the wrong thing with our own money.
WHAT WE BUILD
The software your team uses but customers never see. Field apps, dispatch tools, commissioning workflows, internal admin systems. Kalmar’s commissioning app runs at ports worldwide with 17 languages and offline mode. Familjehem Göteborg manages foster care workflows with BankID and GDPR compliance built in.
Concept to launch, with a focus on shipping something users actually pay for. Avidnote grew to 70,000 researchers across 100 universities including Princeton and Cornell. Meela Health raised €2.6M in seed funding on the product we built. Linkbound hit $25K ARR in its first week using our build-measure-learn approach.
The plumbing that makes legacy systems talk to modern interfaces. SAP integrations, ERP connectors, PIM bridges, custom APIs, payment gateways, Jira Service Desk extensions. Most of our enterprise clients started with one integration and turned into multi-year partnerships.
OCR, ML pipelines, agentic workflows, data extraction systems. We built an OCR system for an industrial client that cut serial number extraction from days to 2 minutes using AWS Textract and custom models. We’ve shipped AI inside Avidnote, Robinize, Aktarr’s content workflow, and several internal client tools. Practical AI that earns its cost, not demos.
Moving off platforms reaching end of life or hitting performance ceilings. Magento 1 to Magento 2 with custom modules. Monolith to services. Multi-stack consolidations across multiple countries. Indexing times dropped from days to 2 minutes after the Arvid Nilsson rebuild. The multi-country financial group we worked with consolidated stacks across multiple national entities.
HOW WE WORK
Discovery is a working week, not a formality. We map your business context, pressure-test your assumptions, and find the parts of your spec that won’t survive contact with reality. Sometimes that means we recommend a smaller build than you came in for. Sometimes it means three iterations within the same budget instead of one. Either way, you start development with a plan you trust.
We deliver in two-week increments with demos tied to business KPIs. After every cycle you see what worked, what didn’t, and where the budget goes next. We built Linkbound to $25K ARR in its first week by testing a hypothesis before building a full product. We helped Greenfee365 grow bookings by 63% and order values by 121% on the same platform using the same approach.
We run our own SaaS products. Avidnote has 70,000 researchers across 100 universities including Princeton and Cornell. Robinize was Product Hunt’s #1 product of the day. We co-own Hidroxa, which grew 33% in revenue after the platform rebuild. When we recommend a stack, a pricing model, or a go-to-market move, it’s based on what we’ve shipped and paid for ourselves.
WHAT CLIENTS SAY
The PDT app was our first big step into the digital world using apps and Cloud solutions. By implementing this app, we could, with one tool, solve multiple issues that we had with our delivery process of new machines to our customers. The app helps us improve the machine quality, shorten our lead time and increase our cash flow.
Zendev understood our vision of connecting women with the right therapists. They improved the platform, were easy to collaborate with, and meeting them in person built real trust.
What I appreciated most in our partnership was the way I could explain our business to you and how we could develop the online store to fit our needs.
The 110% commitment we received from Zendev was truly remarkable.
We struggled with outdated AutoCAD renders and no good way to manage large-scale 3D scans. Zendev solved both.
We needed a tech partner who could help us scale Greenfee365 into the global marketplace, and Zendev exceeded our expectations.
Their team developed custom solutions that optimized our booking platform, resulting in faster load times and an improved user experience
Zendev provided the solution we needed. Implementing Progressive Web App (PWA) significantly improved our site speed, Google rankings, and conversion rates. The new platform has driven a 33% increase in revenue and 17% more users.
WHY ZENDEV
Nikola Mirković runs Gothenburg. Senad Šantić runs Mostar and Sarajevo. Same company, two countries, no agency-and-vendor relationship in the middle. You get Swedish business culture on the client side and 100+ engineers in offices 90 minutes flight away, working the same hours you do.
Code ownership is yours from day one. Repos, documentation, runbooks, infrastructure access all live in your accounts, not ours. If you ever want to bring development in-house, we hand off cleanly. Several clients have done exactly that, and none of them regretted starting with us.
Information security and quality management certified. Data handled and stored in the EU. Most of our engineers have 5+ years of experience.
EXPERTISE
Our stack is built around handoff quality. We work with the same design and development tools used by the teams building Spotify, Figma, and Klarna.
FAQ
Custom software projects at Zendev start at €40,000 and scale based on scope, team size, and timeline. Hourly rates land between what you’d pay an in-house Swedish senior developer and offshore alternatives, because our delivery team works from Mostar and Sarajevo while client management happens in Gothenburg. Most enterprise engagements run €100,000 to €500,000 in the first year. We give a fixed estimate after the discovery week, not before.
A working MVP usually ships in 3 to 6 months. A full enterprise platform takes 6 to 18 months depending on integrations and scope. The Kalmar PDT mobile app reached production at ports worldwide within a year. The myflow app shipped in 3 months. Timelines compress when scope is clear and stretch when integrations to SAP, ERP, or legacy systems are involved. Discovery week gives you a real estimate.
Off-the-shelf software solves common problems cheaply. Custom software solves your specific problem, often the one no off-the-shelf product handles. We’ve told clients to buy a SaaS product instead of building one. We’ve also rebuilt platforms after off-the-shelf solutions hit a wall at scale. The honest answer is most companies need both. Custom builds make sense when the workflow is core to your business and the integrations are non-trivial.
You own everything from day one. The code, the repository, the documentation, the infrastructure, the deployment pipelines. All of it lives in your accounts, not ours. We don’t hold code hostage, we don’t lock you into proprietary frameworks, and we don’t require ongoing fees for access to what we built. If you ever want to bring development in-house or switch providers, you take everything with you.
Every engagement starts with a discovery week where we map your business context and pressure-test your requirements. Development runs in two-week cycles with demos tied to business KPIs, not just feature lists. Bi-weekly demos, phase gates, and budget checkpoints are built in. Most clients see working software in the first month. We don’t ship in 6-month silence and reveal the final product at the end.
Yes, that’s how about half of our engagements run. We embed engineers into your team, join your standups, use your tools, and report into your tech leadership. Or we take on a defined scope your team doesn’t have capacity for and ship it alongside them. Loopme, myflow, and several of our enterprise clients run this way. We don’t require you to outsource everything to work with us.
You leave with everything you came in with, plus what we built. Code, docs, runbooks, and infrastructure access stay with you because they were always yours. We provide a structured handover, knowledge transfer sessions, and full documentation of architecture decisions. Several clients have transitioned projects in-house after we helped them build the foundation. None of them regretted starting with us, and we kept working with most of them on other projects later.
