Why SaJo Consulting?
Software development with the long view.
Plenty of companies write software. We build solutions that still work years later. Transparent processes, modern technology and direct contact are what turn an idea into a product that lasts.
One team, start to finish
You work with the same people throughout — people who know your project and your requirements. Direct contact instead of changing faces.
Software without compromises
No off-the-shelf product bent into shape. We build what fits your processes and your goals.
Built to last
We rely on proven technology, sound architecture and scalable design, so your software still holds up tomorrow.
You always know where your project stands
Short development cycles, regular reviews and clear milestones keep you informed throughout.
More than just development
After go-live we stay on board for maintenance, further development and support – so your software can grow with your business.
Excellence isn’t a promise here – it’s a method.
AI makes software development fast. Our process makes it good. Four principles carry every project:
Architecture to arc42
A documented, standardised architecture as a dependable foundation. Every decision is recorded and traceable – years later too.
Defined processes & quality gates
Defined stages instead of ad‑hoc development: each phase has clear entry and exit criteria that are measured, not assumed.
Security by Design
Security isn’t bolted on at the end. It is part of every development cycle – from specification through to release.
Human in the Loop
AI accelerates – people decide. Experienced architects and developers review and take responsibility for every result.
How a project runs
From the idea to finished software.
Every successful software project starts with a clear structure. That is why we work in an open process where you always know where things stand and what comes next.
Analysis & concept
Together we go through your requirements, processes and goals. The result is a technical concept that development builds on.
Planning & architecture
We settle the architecture, the technology and the milestones. That gives the project a stable base to grow on.
Development
Our developers work in short cycles. Regular reviews and working increments let you follow progress at any point.
Testing & quality assurance
Before release the software is tested thoroughly — quality, security and performance first.
Go-live & further development
After a successful launch we stay on with support, maintenance and the continued development of your software.
Industries & solutions
Digital solutions for different industries.
Every industry has its own processes and its own problems. Our experience lets us build software that fits into what already exists and earns its keep.
Manufacturing & industry
Digital solutions for production, manufacturing and logistics – from process automation to connecting machines and ERP systems.
Healthcare
Custom software for practices, laboratories and medical institutions – secure, efficient and built for sensitive data.
Retail & e-commerce
Tailored applications for digital sales, shop systems and interfaces to the platforms you already use.
Public sector
Digital applications for public authorities and institutions – with a focus on usability, security and accessibility.
Logistics & transport
Software for planning, steering and tracking logistics processes – transparent and efficient.
Solutions beyond a single industry
Not every problem fits neatly into an industry. We build software shaped around your requirements and your way of working.
Selected projects
Custom software, in the field.
No two companies need the same thing. So we build software that simplifies processes, automates routine work and pays off over time.
Technology
The technology we build with.
We rely on proven frameworks, modern architectures and cloud technology to build software that is fast, scalable and still maintainable in a few years.

About us
We build software because we like building software.

SaJo Consulting GmbH builds custom software for companies that want to digitalise, automate and genuinely improve the way they work. Together with our clients we create applications that are sound underneath and noticeably easier to live with day to day.
Our team of experienced developers accompanies projects from the first idea through the concept to a successful rollout — with modern technology, short development cycles and a working relationship between equals.
What sets us apart? We listen, we understand what our clients are up against, and we build software that fits what they actually need – not a standard product, but something genuinely built for them.

FAQ
Frequently asked questions
Do you build custom software or standard products?
We build tailored software, shaped around your requirements and your business processes. You get a solution that fits your company rather than the other way round.
What technology do you use?
We work with Angular, Java, Spring Boot, AWS, Azure, Docker, Kubernetes and REST APIs, among others. The stack is chosen per project, according to what the project needs.
Do you take over existing software projects?
Yes. We extend existing applications, modernise them, and take over projects already under way.
How does a project with you run?
We start by going through your requirements together. Then come the concept, development, testing and going live. Throughout, we work openly and in close contact with you.
Do you offer support after go-live?
Yes. After launch we can stay on with maintenance, support and continued development.
Do you build AI solutions?
Yes. We build and integrate AI-supported applications, automations and assistance systems that make processes more efficient.
Do you work remotely only?
No. We work remotely and on site with our clients – whichever makes more sense for the project.
Can you connect existing systems and interfaces?
Yes. We build custom interfaces and connect existing systems — ERP, CRM, e-commerce or third-party — through modern APIs.
