The next wave of digitalization.

We build software for the next wave of digitalization - web apps, mobile apps, internal tools, automations, AI integrations, data pipelines, and Web3 platforms. Whatever takes manual work off your plate, speeds up a process, or replaces a costly off-the-shelf tool, we can design and ship a custom solution for it.

All kinds of businesses - from solo founders and small companies to established enterprises, public institutions, and agencies looking for a technical partner. We work locally in Zagreb and across Croatia, throughout the EU, and worldwide. If you have a real business problem that software could solve, we'd like to hear about it.

Yes - we regularly work as the engineering partner behind marketing agencies, design studios, and consultancies that don't have in-house developers. White-label, named, or hybrid arrangements all work for us. If you have a recurring need for reliable engineering or a specific client project that needs technical depth, get in touch.

Yes - native iOS, native Android, and cross-platform apps with React Native or Flutter. We've shipped everything from focused single-purpose tools to full consumer products with hundreds of thousands of monthly users, including the backend, APIs, push notifications, and analytics that keep them running in production.

Yes - fast marketing sites, SEO-optimized landing pages, web apps, online stores, internal dashboards, admin panels, booking systems, and full SaaS products. We use modern frameworks, custom design, and accessible, performance-first code. No templates, no page builders, no recurring license fees.

Absolutely - process automation is one of our core services and the practical first step in any digitalization initiative. We replace manual work, spreadsheets, and constant tool-switching with custom automations that connect your CRM, accounting, e-mail, e-commerce, and any other systems you already use. Most clients see hours saved per week within the first month, and the savings compound over time.

Yes - anything from a smart chatbot on your website to custom AI tools that summarize documents, draft customer replies, analyze data, route tickets, or trigger actions across your stack. We build with the leading models (Claude, GPT, Gemini, and open-source LLMs) and pick the right one for the task, your budget, and your data-privacy requirements.

Most engagements run six to sixteen weeks across our four phases - Research, Design, Build, Operate. Smaller scopes (audits, automations, single integrations) can ship in one to three weeks. We commit to a fixed scope and timeline after the Research phase.

It depends on the project and its scope - there is no one-size price list. The first call is free of charge and commits you to nothing. After a short Research phase you get a written proposal with a fixed price and milestones, and we always agree the price before any work starts, so there are no surprises.

Both. We regularly take over existing codebases for audits, rewrites, performance work, or feature delivery - and we're equally happy starting a greenfield product on day one.

Yes - our Operate phase covers monitoring, security patches, bug fixes, and continuous improvements. We offer monthly retainers from light-touch support to full product ownership, scaled to what your software actually needs.

Yes. Once the work is paid for, you own the source code, the design files, the data, and all intellectual property created for you during the engagement - handed over in your own repositories and accounts. Our pre-existing tools and any third-party or open-source components stay under their own licences; for our tools you get a licence to keep using them in your product. We build in no kill switches and no recurring dependencies on us, so you can take everything to another vendor whenever you choose.

Yes - most of our clients are business owners, operators, or domain experts without a deep technical background. We translate business goals into technical decisions, document every choice, and explain trade-offs in plain language. Your job is to know your business; ours is to turn that into software that actually works.

We're platform-agnostic. There's no single stack we push on every project - each engagement is individual and calls for a different set of technologies, so we pick the right tools for the problem, your team, and the long term. The constant: we only work with modern, actively maintained technologies that will still be supported and easy to hire for years down the line.
