Custom Software Development
Off-the-Shelf Software Doesn't Fit Your Operations?
Stop forcing generic tools into unique processes. Get custom applications built specifically around how your teams actually work.
When your processes are a competitive advantage, generic software quickly becomes a liability.

Select the challenge that best reflects your situation to see how we address it.
Process Workarounds
Teams spend more time adapting to software limitations than doing meaningful work.
Manual Process Persistence
Critical workflows still rely on spreadsheets or paper because no existing tool truly fits.
Competitive Disadvantage
Generic tools produce generic results while competitors move faster with tailored solutions.
Business impact
Reduced productivity, employee frustration.
Real cost
20-30% productivity loss, €100K+ annually in wasted time per team
Business impact
Human errors, compliance risks, inability to scale operations
Real cost
5-10% error rates, regulatory exposure, missed growth opportunities
Business impact
Lost market position, inability to optimize unique processes
Real cost
Missed revenue opportunities, higher operational costs than optimized competitors
Let's discuss your specific challenge and outline a clear path forward.

Custom Applications That Fit Like a Glove
To optimize unique workflows, we build software that mirrors how your teams think and operate — not how off-the-shelf vendors assume you should work.
Process-First Design
We start with real workflows, not technical constraints.
-
In-depth process analysis and mapping
-
User experience designed around real operating conditions
-
Support for offline or low-connectivity scenarios
Rapid Prototyping & Testing
Validate the solution before committing to full development.
-
Interactive prototypes tested with real users
-
Iterative design driven by direct feedback
-
Proof-of-concepts validated with real data
Production-Ready Development
Applications engineered for reliability, scale, and long-term use.
-
Scalable architectures that grow with your organization
-
Seamless integration with existing systems
-
Ongoing maintenance and long-term support
Pragmatic and Proven Technology

Frequently Asked Questions
Everything you need to know before you decide to work with us.
We typically start within 2–3 weeks from the first conversation. The timeline depends on how quickly we can run the technical assessment workshop (usually within a few days) and finalize the commercial agreement.
For urgent situations, we’ve started projects in as little as one week. We never skip discovery — rushing into development without proper scoping leads to costly delays later.
Your project team usually consists of 2–4 people depending on scope: a Technical Lead, a Frontend or Data Engineer, and a Project Manager. For complex initiatives, we add specialists as needed.
You’ll meet your dedicated team during kickoff, and they remain your consistent points of contact throughout the project.
We work in two-week sprints with clear milestones. You’ll have a weekly check-in call to review progress and priorities. Between calls, communication happens via Slack or email.
At the end of each sprint, you see working software — not just status updates.
For well-defined projects, we offer fixed-price delivery with milestone-based payments.For exploratory work, we use time-and-materials with a clear monthly budget cap.
We’re transparent about costs from day one and flag any scope changes early.
