Applied AI & Intelligent Systems
AI that does real work inside your operation: autonomous agents, machine-learning models, computer vision, and intelligent automation, integrated directly into the tools and products you already run.
Applied AI · Custom Software · Physical Systems
We build what off-the-shelf can't.
Notum is an applied-AI and software engineering studio. We design, build, and ship the complex systems generic tools can't handle. And when the problem reaches into the physical world, we build the hardware too.

The gap
Off-the-shelf breaks exactly where your business is hardest.
The processes that actually differentiate you (the edge cases, the deep integrations, the real-time decisions) are the ones generic software was never built for.
That's the work we take on: custom AI and systems engineered around your operation, not the other way around. No templates. No black boxes. Senior engineers, accountable for the outcome.
What we build
Depth, not a menu.
Three capabilities, one team. AI and software are the core. Hardware is the edge most firms can't offer.
Complex Software & Cloud
The mission-critical platforms off-the-shelf can't deliver. Custom web applications, high-performance APIs, and secure, scalable cloud architecture, built AWS-native with infrastructure-as-code from day one.
Physical AI & Custom Hardware
When intelligence needs a body. We write the autonomy software that drives robots and connected devices in the real world, and design the electronics, sensors, and enclosures to match. Most software firms stop at the screen. We don't.
The throughline
We make software think. Then give it a body.
Most software stops at the screen. We engineer intelligence that perceives, reasons, and acts, from cloud architecture down to the circuit board.
Why Notum
We've already shipped AI into the physical world.
Writing software that controls an autonomous robot in an unpredictable environment is one of the hardest things in applied AI. We do it. So when your problem is "merely" a complex enterprise system, a custom model, or an integration nobody else will touch, it's well within reach.
Code is the foundation
Any firm can build an app. Very few can design the sensor that feeds it and engineer the system around it.
Complete problem-solvers
The valuable problems aren't solved by code alone. They need a team fluent from cloud architecture to circuit board.
One senior team, full stack
You work with the people who build, not a layer of account managers. From database to device, one accountable team.

How we work
A clear path from problem to production.
- 01
Scope
A focused discovery sprint. We map the problem, the constraints, and what success means, and tell you honestly if we're the right team.
- 02
Architect
A clear technical plan and a realistic roadmap before a line of production code. No surprises, no black boxes.
- 03
Build
Senior engineers, short feedback loops, working software early and often, so you steer as we go.
- 04
Operate
We don't disappear at launch. We monitor, harden, and evolve what we ship into the long term.
The team
Founded and led by an engineer.
Notum is led by Milan Rajčević, an engineer with 15+ years building neural networks, machine-learning systems, and autonomous robotics: the kind of deep-tech work most studios outsource or avoid. We keep it in-house.
That focus is the point: we'd rather be the obvious choice for a handful of genuinely hard problems than a vendor for everything.

The invitation
Bring us the part nobody else can build.
If off-the-shelf tools and generalist shops can't deliver it, that's exactly where we start.
