Web studio in Belgrade

Websites, apps & AI. Built to grow your business.

We design and build fast websites, mobile apps and AI features, then help them rank and convert. One senior team, from first idea to launch and long after.

One team, start to finish

Most projects stall between vendors: one designs, another builds, a third handles SEO, and nobody owns the result. We do it all in one place: strategy, design, web and mobile development, AI, QA, SEO and marketing. You get one team that is accountable for the outcome, not just the code.

Launching something new, or stuck with a site that doesn’t bring in clients? Tell us where you are, and we’ll show you the clearest way forward.

How we work

From first call to launch day, and long after.

Four clear steps, full visibility at every one of them. No black boxes, no surprises.

  1. Step 01

    Strategy

    We dive deep into your industry, analyze your competitors and define your ideal audience. Those insights become the foundation for your design, content and marketing, so every move serves your goals.

  2. Step 02

    Design

    From color and layout to sitemap and visual style, every detail is crafted with purpose. Your brand comes to life in a design made for your business, not adapted from a template.

  3. Step 03

    Develop

    We turn ideas into clean, scalable code. Your site is built on a development server, so you get full visibility and real-time access as it comes to life.

  4. Step 04

    Support

    Launch day is just the start. From design updates and marketing to reliable maintenance, we are here for the long haul, supporting your site every step of the way.

B2B marketing & web design

Built for the way businesses buy.

B2B buyers research for weeks, compare options and have to convince a whole team before they reach out. We build websites and content that answer their questions, earn their trust and turn visits into qualified inquiries.

Clients

What our clients say.

  • We brought JOLEY.dev in for frontend work and ended up leaning on them for half the product. They built big parts of our card editor and Stampy, our AI assistant, and they’re usually the ones who spot the edge cases before our customers do.

    Product teamHeartStamp

  • Getting CAD drawings to show up properly in the browser was the part we worried about most. They got it working with Three.js and built the interface around it. Working across borders was never an issue, and questions rarely waited long for an answer.

    Engineering teamAntek AAD

  • We needed one app that works for dispatchers, drivers and managers without confusing any of them. The driver side is the best part: accept or decline a trip, see it on the map, done. They built it end to end and kept us in the loop the whole way.

    OperationsKloudIP

  • They were there from the first line of code and stayed with us for four years. They built the platform our clients use every day for documents and deals, and every time the business changed direction, the product kept up. That kind of continuity is hard to find.

    ManagementDocsCube

  • Our clients run their business on Pantheon, so anything we deliver has to fit into it cleanly. The custom web apps they built did exactly that. They were also good at sitting down with our clients and turning a messy list of requirements into something that actually works.

FAQ

Questions, answered.

What people usually ask before working with us. Anything else? Just ask.

Ask us a question

How much does a website or app cost?

Company websites start at €1,200, online stores at €2,500, AI features at €1,500 and mobile apps at €5,000. SEO starts at €450 per month. All prices exclude VAT. The final price depends on what you need: after a short call we send a written quote that breaks it down, so you can see exactly what you pay for. Work only starts once you approve it, and there are no hidden costs.

How long does a project take?

A company website usually takes four to eight weeks from the first call to launch. Online stores, apps and AI features take longer, depending on scope. Before we start you get a timeline with clear milestones, and you see progress every week.

Who owns the website and the code?

You do. Once the project is paid, the design, code and content are yours, and the domain, hosting and analytics accounts are set up in your name. You are never locked into working with us.

What happens after launch?

We stay with you. We offer ongoing support with updates, security, backups and new features, plus SEO and marketing to keep the site bringing in clients. Support plans start at €80 per month, and you choose how much support you want, or none at all.

Can you improve or take over our existing website?

Yes. We can review your current site, fix what slows it down or keeps it from ranking, redesign it, or take over its maintenance from another developer. We will tell you honestly whether it is worth improving or better to rebuild.

Do you work with clients outside Serbia?

Yes. We work in English and Serbian, and already build products for companies outside Serbia. Calls, updates and documents all happen online, so distance is never a problem.
