CoreLine

CoreLine, based in Zagreb, builds and modernizes custom software for product and operations teams working in regulated, high-growth, and operationally complex environments. Client work spans YoungPlanet Digital, a sustainability platform for families across the UK running since 2020, Insync Insurance's quoting system, and Marex.es's digital transformation of marina water and energy management, alongside a 2025 mobile app for Plitvice Lakes National Park that gives visitors real-time navigation.

Work is organized around five disciplines: product design, development, project management, quality assurance, and product management. Design focuses on intuitive interfaces built with a mix of tools and direct user insight. Development is described as clean and scalable rather than quick-and-dirty, and the studio runs an AI-driven process through delivery. Project management is framed as bringing structure to ideas, while QA is treated as the stage where trust in the product gets built, and product management carries work from initial idea through to launch.

Beyond client engagements, CoreLine has built its own products, including CoreEvent, an event management platform; NoCapp, a SaaS tool for real-time visitor engagement on websites; and Corex, an outsourcing platform aimed at helping Europe's fastest-growing companies scale. The Insync Insurance project specifically produced a faster, smarter quoting system credited with improving both efficiency and customer satisfaction, and the Marex.es engagement addresses marina infrastructure rather than a typical consumer app, reflecting the studio's stated focus on operationally complex builds.
