Custom software — when off-the-shelf does not fit
Business-critical web back-ends, line-of-business applications and APIs — for processes that off-the-shelf software cannot cover properly.
We build software for processes that define your competitive edge. Where SAP modules fit 70 % and SaaS solutions miss the last 30 %, we begin.
When do you need this?
Your processes are your competitive edge
a standard solution would push you back to industry average.
You have an existing ERP/MES
that does not cover the last 20–30 % of your requirements — but you do not want to replace it.
You need an application
that integrates several legacy systems without forcing case handlers into Excel buffers.
No off-the-shelf tool exists
for your specialised process — or it would cost more over its lifetime than a custom build.
What we deliver
Business-critical web applications
in Java/Spring (back-end) and React/Next.js (front-end), GDPR-compliant from EU data centres.
REST and GraphQL APIs
as a clean integration layer between your legacy systems.
Event-driven architectures
with Apache Kafka for high throughput and decoupled services.
Clean domain modelling
(Domain-Driven Design, Event Storming) — no big-ball-of-mud applications.
Tests, CI/CD, code reviews
and security by design as standard, not add-on.
Full documentation,
so your IT can evolve the application autonomously.
Methodology
- 01
Analysis call
60 minutes on your specific project — which process, which systems, which bottleneck.
- 02
Next step
if the scope is clear, you receive an offer with scope, milestones and acceptance criteria. If requirements, the domain model or integrations need to be worked out first, we start with a paid concept phase.
- 03
Implementation
once commissioned, we build iteratively in 2-week sprints — with a demo after each sprint.
- 04
Rollout & operations
go-live in the real process, then operations, adjustments and further development on request.
Typical use cases (industry-focused)
Production-planning tool
for a mechanical engineer, integrated into an existing SAP system
Order tracking
with real-time view across plants and suppliers
Customer-onboarding platform
with document AI and Camunda workflow for regulated industries
Field-service app
(PWA, offline-capable) for service and maintenance teams
Frequent questions
How long does a typical project take?
Analysis call to go-live: typically 3–9 months depending on scope. First productive version often 6–10 weeks.
Can we evolve the module ourselves later?
Yes. Clean architecture, full documentation and knowledge transfer to your IT are part of every delivery.
Where does the software run?
EU data centres by default (Hetzner, Azure EU, AWS EU). On-premises or hybrid on request.
What about the source code?
Source-code transfer is part of the work contract. Pre-existing Monadion building blocks remain Monadion property.
Which process costs your team time every day?
In a free analysis call we look at it together and clarify whether automation makes sense.
