CityX
Smart city platform · 2023 · Founder, Full-stack
A modular platform cities run their services on.
CityX is a modular platform cities run their services on: a citizen app, the core behind it and a console for city staff. More than 30 modules, from fault reports to live departures, connect to the systems a city already has. In production since 2023.
AI self-driving business: built, marketed, sold and run by AI agents, with a human directing.
What Krnic did
Krnic designed, built and operates the platform: the module engine and gateway in the Core, the citizen app, the role-scoped Console, and the integrations with city systems and open data. The business around it is run by twelve AI agents with defined roles, under human approval.
