AI · Custom systems · Security
We build custom AI and systems. And we keep them secure.
From custom development to penetration testing.
We design, build and hand over software your company actually uses every day. Scope and price clear up front.
30+ systems deployed across 5 industries · Czechia and Slovakia
What we do
Three areas.
All under one roof.
Every engagement starts with scoping. We define what gets built, by when and for how much, before development begins.
01 · Main area
AI implementation
AI agents and features built straight into your operation. Customer assistants, internal copilots, document and data automation. We start from the process that matters.
What we’ve built →02
Custom systems and migration
Software built around your process, not the other way round. New systems from scratch, or a clean move off ABRA, Pohoda and Helios without the old baggage.

Security and penetration testing
We test your apps, API and network like an attacker. We get you ready for ISO 27001, SOC 2 and GDPR audits. And we fix the findings with you, not just list them.
Learn more →Not promises, deployment
We don’t talk AI. We run it.
These aren’t bought-in case studies. They’re products we build and run ourselves. They serve real customers every day.
klientbox
An AI receptionist that fills the calendar
Booking, reminders and client reactivation for service businesses. The assistant replies and books into open slots itself.
Live with clientsOutreach engine
Researches, writes and sends at scale
It studies each contact, writes the message and sends it, with safeguards that keep sending clean and within the rules.
In productionInternal copilots
Assistants right inside your tools
AI that reads your documents and answers in plain language. Built into the systems your team already works in.
DeployedSecurity and compliance
Security you can actually work with.
Not a report for the drawer.
We fix the findings with you and harden the system, not just hand over a list of bugs. The certificate is issued by an accredited authority; we get you fully ready for it.
Hands-on work
- Penetration tests of web, API and network
- Vulnerability assessment
- Hardening and secure architecture
- GDPR implementation
For certification
- ISO 27001 readiness and ISMS
- SOC 2 (Type I and II)
- Gap analysis and controls
- Audit support
The certificate is issued by an accredited authority, not us. We build the controls, test them and stand beside you, so the badge on your site is backed by security that actually holds.
I want a pentestHow we work
No surprises. By design.
01 · Brief
A clear brief
Before we write a line of code, we know exactly what we’re building and why.
02 · Timeline
A deadline that holds
We treat the delivery date as a commitment, not an estimate.
03 · Ownership
The code and data are yours
You own the source code from day one. No vendor lock-in, you can carry on alone anytime.
