QSD Information

At QSD, we believe that high standards and human-centered design are non-negotiable. Founded in 2015 and headquartered in Mostar, we've grown from a small dev hub into a specialized boutique agency delivering advanced digital solutions for clients across Europe and North America. We craft custom software products, with a strong focus on: AI & ML solutions IoT platforms SDKs and API integrations SaaS applications Mobile-first and cross-platform systems Our team blends deep engineering expertise with a product mindset. While we started out building high-impact native mobile applications (and we still love them!), we've since evolved to partner on AI-powered tools, backend-heavy platforms, and data-driven applications that scale. How We Work We don't believe in body-leasing. We believe in long-term partnerships, strong ownership, and building products as if they were ours. Whether supporting enterprises like Philips, or helping mid-sized companies and funded startups go from MVP to scale, our goal is the same: launch, learn, iterate, and deliver lasting value. We operate with lean teams, fast decision-making, and a commitment to quality that our clients often say feels "rare in this industry".
