exe.cutor d.o.o
5
(13 reviews)
Solving complex challenges with AI, custom software, and 20+ years of experience
Highly recommended
exe.cutor is a Zagreb-based software company founded in 2013. We design and build custom software end to end: web applications, desktop applications for Windows and macOS, and embedded electronics built around microcontrollers. Clients come to us for work that does not fit off-the-shelf products: custom business systems, integrations (fiscalization, e-invoicing, identity and authentication), hardware-backed access control, and long-term maintenance of systems running in production. We use AI to accelerate delivery while engineering judgement and accountability stay with our team. Our team of nine, including associates, has delivered across banking, telecommunications, public-sector and environmental systems, energy management, fleet monitoring, tolling, CRM and gaming platforms. Core stack: Java and Spring Boot, C# and .NET Core, Angular, React, TypeScript, PostgreSQL, SQL Server and Oracle, Docker and Kubernetes. For AI work we run locally deployed models — document intelligence, computer vision and speech — so that client data never leaves their perimeter. Each of our engineers brings 15 to 18 years of delivery experience from before exe.cutor. We work in English and Croatian.

Top awarded
Our range of expertise is extensive and interdisciplinary. When developing new solutions, we focus on design and technology. Our own playfulness is a constant motivator to constantly try out new paths and solutions. From the idea to the finished product is a long way. That's why we've built our own digital playground. What is a trend today could be the new standard tomorrow and already outdated next week. So that the digital labyrinth doesn't remain a one-way street, there is Becklyn. Becklyn develops digital products, strategies, and innovative and technical solutions for medium-sized businesses. We employ a large team of software developers from Frontend, Backend, Operations, and Dev-Ops.
