Custom software
Applications that mirror your processes, instead of your team having to adapt to an off-the-shelf product.
These are the tasks we take off your hands
Customer portals & dashboards
A place where your customers handle everything themselves, plus reporting that shows your team the numbers that matter.
SaaS platforms
Multi-tenant platforms with roles and permissions, single sign-on, subscription billing and your own branding.
Interfaces & APIs
We connect CRM, ERP, accounting and external services so data no longer has to be copied over by hand.
Automation & AI agents
Recurring processes run on their own. AI agents read inboxes, classify enquiries and create the matching records.
Operations & further development
We host your software in the cloud or on your own infrastructure, keep it up to date and grow it together with you.
How ideas turned into working software in a matter of months
From onboarding on the fly to a platform of its own
- An onboarding platform where lessons are created and managed in one place
- A question and answer board plus an AI chat that gets new employees moving straight away
- Runs as a product in its own right today and is still operated by us
From scattered routines to one internal tool
- Task management where recurring routines are stored as workflows and run at the push of a button
- Equipment documentation that logs maintenance on machines, with photos added straight from a phone
- In daily use in our own operation and growing with every routine that is added
From an idea to a booking platform of its own
- A market-ready SaaS booking solution in three months
- Booking calendar for customers, dashboard for owners and staff, automatic confirmations by email
- Subscription billing through Stripe and infrastructure that grows with the number of bookings
The difference only shows after two years
Doing it yourself
- Decisions without experience from comparable projects
- Finding, onboarding and keeping developers
- Mistakes surface only once they are expensive
- Servers and operations run on the side
- No plan for the day someone hands in their notice

The team behind your next project
Jan Umbach
Founder and software developer
Jan owns architecture and implementation and builds the systems underneath. He is your contact whenever things get technically demanding, for example with complex algorithms or when AI should be built into your software in a way that actually helps. His decisions keep your software maintainable and extendable for years.

Alexander Röse
Software development and consulting
Alexander is your first point of contact. He listens to your plan, judges what it means technically and works out a solution with you that holds up in daily use. Alongside development he owns design and usability, so your team enjoys working with the software.
+49 1522 1435483Our Location
From our office in Melsungen near Kassel we support medium-sized companies with their software projects.
We are based in northern Hesse, right on the A7 motorway. From here we look after clients across the entire DACH region.
You rarely need to make the trip, though. We work digitally, from the first analysis through development to handover.
You know what your business needs. We know how to build it.
You know your processes, your customers and the points where things get stuck every day. What is missing is someone who turns that into working software. That is where we come in.
We first clarify what the solution has to do, then build it so your team works with it day to day instead of around it. No off-the-shelf software you have to adapt to, but a solution that follows your processes.
Your next project starts with a conversation
In 30 minutes we clarify what is possible, what it costs and how quickly it can happen. That applies to process automation just as much as to custom software or an API integration.
You talk directly to a developer who can assess your project technically. Afterwards you'll know what an implementation would look like and where you stand on time and budget.
