We build the software businesses run on.
Chronum is a small engineering company in Serbia. We build web applications, internal systems and AI features for companies that need software to work every day, and we stay involved after it launches.
Interfaces people use every day, APIs, permissions and the workflows the company actually follows.
Documents in, retrieval over your own data, a model step, an action in the system, and human review where it matters.
The systems you already run, connected through APIs, files and scheduled work so information stays in one shape.
Structured business data moving through the system, with history kept and access controlled.
Continuous development and operation after launch, by the people who designed the system.
Every system we build runs through these layers, and we stay with it once it is live.
Interfaces people use every day, APIs, permissions and the workflows the company actually follows.
Most of our work starts with a business that already knows what it needs, and needs someone who can actually build it.
What we do
Four services. Most projects use two or three of them together.
Internal platforms, dashboards, customer-facing applications.
Document processing, retrieval, assistants, integrations.
Making a business readable to AI assistants and search.
Continued work on systems that are already live.
Experience across healthcare, solar engineering, retail, e-commerce and internal business systems.
IndustriesHow we work
You talk to the people responsible for the technical work. No account layer in between, and no summaries of conversations you were not part of.
Scope, responsibilities and pricing are agreed before development starts. If something changes, we say what it costs before we build it.
We can stay involved after launch to keep developing the system, add integrations and handle the issues that only appear in production.
We work with AI in two ways
Features that do real work against your own data and permissions.
- Document processing
- Retrieval over internal data
- Assistants with system access
- Automation of manual steps
- Integrations
Making what your company does unambiguous to the systems that answer questions about it.
- Structured data
- Entity clarity
- Content architecture
- Technical discoverability
- Citation audits
You work directly with the engineers responsible for the technical work.
Chronum is deliberately small. Scoping, architecture and the difficult parts of the build stay with the engineers who will keep the system running afterwards, which is why we take a limited number of projects at a time.
