Entrepreneur · Developer · Thinking partner
I develop ideas.
And the software
to go with them.
I build software, products and companies. I enjoy thinking things through with people who have something in mind — and getting to work together.
01 / From the workshop
Built. Tried.
Still curious.
An idea rarely stays an idea for long. A selection of what I’m working on.

Explore the project02 / A little about me
I like understanding things.
And making them work.
For more than 30 years, I’ve been connecting technology, products and business. What keeps it interesting is the people — and the next good question.
Sometimes it takes a prototype. Sometimes, a good conversation first.
Why people come to me
A question is a good start
Software
Build or buy, legacy or greenfield — and what the code can really do once you look inside.
Product
What gets built and what deliberately doesn't — and how to tell early whether it holds.
Architecture
Scaling paths, interfaces, technical debt — and the interest it charges.
Organization
Teams, responsibility, speed: structure follows decisions, not the other way around.
Risk
Technical, regulatory, entrepreneurial — assessed realistically instead of moderated away.
Governance
Who decides, who controls, who is liable — settled before it matters.
Regulation
Compliance read as a design constraint — build it in early and you're faster later.
Investment
Cap table, valuation, roles: capital tied to work and responsibility.
Responsibility
The question behind all the others: who bears the consequences — and do they know?
Experience, perspective — and a life beyond the screen.

comes together.
pinkstone.group is at the core of my work. Alongside it, there is room for a product studio, advisory work, mentoring and smaller experiments.
At the core of my work
pinkstone.group
At PinkStone, I connect technology, product and growth. We work out what a venture needs, build the right solution and take responsibility for delivery. Our own products and investments grow out of this work, too.

Alongside it
Product studio · a PinkStone brand
fastercode.studio
A studio for business software. Five proven product lines, from CRM and AI operations to a support assistant, are adapted to each process. The whole product is handed over, including the source code. Support can be added as needed.
fastercode.studioAdvisory board
Hangar Strausberg
A place for AI, drones, autonomous systems, robotics and dual-use is taking shape at Strausberg airfield. It offers test environments where new developments can be tried out in practice. I support the venture as an advisory board member.
Personal
Mentoring
Part of my week belongs to founders and people responsible for teams. We work through decisions, product questions and how to work together. Confidentially and at a pace that fits. Sometimes over a walk.
Just say helloSide project · exploring
xy foundry
A side project where I use AI to explore new business ideas. Small experiments that may grow into further ventures.
04 / Thoughts
A thought worth
staying with.
Observations from building, learning and working together. Often about AI, health and education. Always open to another perspective.
All thoughts
Using is not understanding
AI literacy begins the moment someone notices that the answer is wrong.
It's not the model that's expensive
Model costs are the smallest line item in any serious AI project.
Prevention has no dashboard
What didn't happen is hard to bill — and even harder to celebrate.
05 / Working together
Something
in mind?
I enjoy working with people who want to build something. An early idea is a perfectly good place to start.
Let’s get talking
Investment
as an investor who rolls up his sleeves: judgment, network, hands-on work — and sometimes capital.
Board & advisory
when technology, market and organization need to be judged together.
Mentoring
confidential, regular or one-off — for people building under pressure.
Co-building
when deep expertise should become a product or a venture.
Sparring
one concrete decision, a second pair of eyes, an honest verdict.
Early teams
even before product, even before funding — substance counts for more than maturity.
06 / Contact
A good start:
a few lines.
An idea, an open question or a project in progress. Two or three sentences are enough. I read and reply to messages myself.
