Cautus Sistemi

Cautus Sistemi is a software agency and venture builder in Zagreb, Croatia, in business since 2014. We build custom web and mobile applications, CRM and business systems, webshops and AI automation for companies in Croatia and abroad, and we provide on-site IT support for offices in Zagreb and the surrounding area.

We build and run our own products in production. Patrono is a restaurant operations platform for web, iOS and Android, connected to the POS Sector system and to the Croatian e-invoicing system. Staxo is a crypto trading simulator for iOS and Android. Klinika Hub is a system for private practices, integrated with CEZIH, the Croatian national health information system.

Client work includes the official Croatian webshop for Evolution Power Tools, built for Peloza d.o.o., with Stripe checkout, shipping priced off the courier's real tariff and stock levels synced from the point of sale. We also built a custom CRM for an agency that runs delivery platforms for restaurants.

You can work with us in three ways. We build and maintain a system, and you own the code and the data from day one. We build a joint product, where you bring the market and we bring the technology and the team. Or you use one of our own products. We design interfaces and user experience in house, and work with Spiffy Studio on brand and visual identity.

We work in English and Croatian, in Central European Time, and invoice as an EU company, with reverse charge for VAT-registered clients in other member states. We reply within 24 hours and write the scope and the estimate after a first call, at no charge.
