Case Studies
Deep dives into how we solve real problems
Lumera Studio Lab: SaaS for Beauty Salons
A complete business management platform enabling small beauty salons to compete with larger chains.
Challenge
Small beauty salons struggle to compete with larger chains. They lack the resources for professional websites, booking systems, and business management tools that bigger competitors take for granted.
Solution
We built Lumera Studio Lab, a complete SaaS platform that provides salons with a professional website and admin dashboard. They can manage bookings, clients, inventory, staff schedules, and analytics all in one place. Connected to their website, it becomes a powerful business tool.
Digital Transformation for Taxi Companies
Modern booking websites for transport companies in the Croatian market.
Challenge
Traditional taxi companies needed a stronger web presence to stay competitive. Each client had different needs: from a simple landing page showcasing driver experience to full booking systems with instant pricing.
Solution
For Taxi Bogović we built a focused landing page that highlights their drivers and service. For Taxi Krk and Rijeka Airport Taxi we developed mobile-first sites with complex booking forms and instant pricing. Each project was tailored to what the client wanted and needed.
Websites for Student Organizations
Clean, professional websites for academic and educational institutions.
Challenge
Student organizations and educational institutes needed professional web presence to attract members, showcase their work, and communicate their mission. Budget constraints and volunteer turnover made this challenging.
Solution
We built Tourism Lab and Institut za političko obrazovanje (IPO) with clean, maintainable designs. Easy to update, fast to load, and professional enough to represent these organizations to the public.

About Us
Croatian expertise. Global standards.
We are a Croatian-based team with deep expertise in website design, software engineering, and systems. We combine business focus with modern tech stacks and AI to deliver solutions that scale.
Family Roots
Our story began with WELT-ŠPED d.o.o., a family company with over 40 years of experience in transport and logistics. Founded back in the 1990s, technological solutions depended on the owner's knowledge and determination to improvise and adapt.
Evolution
That spirit of innovation evolved into Welt Digital. While we've been doing web design for over 15 years, Welt Digital represents our evolution toward more complex software solutions: SaaS platforms, AI integration, and scalable systems.
Deep Expertise
We have spent decades in transport, logistics, and mobility, and have since expanded into beauty, automotive, and service industries. That background means we understand not just the technology, but the business problems it needs to solve.
Family Owned
Still family owned after 40+ years, we build long-term relationships, not quick wins.
Industry Depth
Decades of experience in transport, logistics, and service industries inform every solution.
Continuous Innovation
From 1990s improvisation to modern AI, we've always found ways to solve problems.

Custom software systems, SaaS products, AI integrations, and high-performance web platforms. We take on technically complex projects with clear business objectives, the kind that need deep architectural thinking, not just implementation.
Fixed-scope phases with clear deliverables and milestones. After discovery we provide detailed estimates and stick to them. Changes go through a structured process, so there are no surprise costs.
15+ years in web design and 40+ years in transport and logistics through our family company WELT-ŠPED d.o.o. Welt Digital is our evolution into complex software, SaaS platforms, and AI-powered systems.
Comprehensive documentation, team training, and a transition period so your team can maintain and extend the system. Many clients stay with us for ongoing support and new features.
Practically. We identify workflows where AI delivers measurable ROI, then build solutions that integrate with your existing systems, no AI for its own sake.
Both: startups building their first major product and established businesses modernizing their systems. What matters is complexity and commitment to building things right.
