DECODE background

DECODE was founded in 2012 by three engineers from the University of Zagreb. Originally starting as a student project, it grew into a full-service development partner trusted by startups and enterprises. Its mission is to help traditional and tech-driven companies solve complex challenges, automate business processes, and bring innovative software solutions to market.

Today, DECODE has grown into a team of 90+ in-house engineers, with 42% holding Master’s degrees in Computer Science (compared to 23% industry average). The company follows a strict “1 team – 1 client” policy to ensure focus and quality, maintaining an average client collaboration of 4.5 years. With a 1:5 QA-to-developer ratio, DECODE enforces rigorous testing practices, and its software impacts over 450 million daily users worldwide.

DECODE’s client base includes Fortune 500 enterprises and high-growth startups, with long-term partnerships with Microsoft, Royal Caribbean, AT&T, ASEE, and RightVybe. The company also spun off Shake, a proprietary SaaS bug/crash reporting tool.
