Our Story

We started working together more than 20 years ago, building payment gateways, webshops and portals for some of the best known companies in Croatia and region. In 2023 we founded InSyBo to do what we do best, with no layers in between: senior engineers working directly with clients on systems that have to work. We combine that experience with our established framework and AI-assisted development, so clients get solutions faster without giving up quality.

What Sets Us Apart

Senior engineers, no layers

You work directly with the founders, who have more than 20 years of experience. No account managers, no hand-offs to juniors, no surprises.

Proven at scale

Our team built Payment Gateway, which at its peak handled more than 65% of all online card payments in Croatia, as well as webshops with millions of products and loyalty platforms with over a million users.

Our own platform, built on experience

Over 20 years we have turned what works in business-critical systems into our own development platform: proven architecture, a strict data layer and built-in security. On top of it we use AI to work faster, while senior engineers make every key decision.

Commonly Asked Questions

It depends on scope. A technical blueprint usually takes one to three weeks. After that we deliver in short iterations, so you see a first working version early in the project, not only at the end.

We deliberately work with a small number of clients at a time, so every project gets senior attention and quick responses. Before we start, we agree on capacity and timelines so that our commitments are realistic.

Custom web and mobile applications, integrations between ERP, POS, webshop and payment systems, replacing spreadsheet-based processes with reliable internal applications, and AI features such as document processing and virtual assistants. We work best with growing and mid-sized companies whose processes off-the-shelf tools no longer handle.

Yes. We can sign an NDA before you share the details of your project. We work with clients in Croatia, the wider region and internationally, in English and Croatian, and our time zone (CET) overlaps well with Europe and partly with the US.
