Founder · Operator · Venture Partner · Vienna

I've started things.
Some worked. Some didn't.

The most useful thing I can offer founders is someone who has been in the room when it gets hard. Not to give advice from the outside, but to actually help.

What I've built

Own
ventures

Not a polished portfolio version. The useful version.

aiones

I built aiones as an AI-powered business process discovery platform, a system that maps how companies actually operate by talking to their people in natural language and turning those conversations into structured process documentation.

We got to an early product and ran pilots with a handful of companies. But we did not find the product-market fit we needed to grow the way it would have taken. I made the call to stop rather than keep grinding at something that was not clicking.

What it taught me

The gap between technically works and people will change their behavior for it is where most AI products die. That shapes how I approach AI adoption work now.

SponsorHive

I co-founded SponsorHive as a platform connecting brands and event organizers around sponsorship. I built the full product and the operational automations behind it.

After several months, the co-founder relationship did not work. We had different ideas about direction and priorities, so I moved on.

What it taught me

Building the thing and running the company are different jobs. Sometimes the most important decision is realizing early that the team is not right.

How I work with founders

Not an advisor outside the room,
but someone in it

I am not a VC. I do not write checks and wait for the update email. I work alongside early-stage founders as the person who can help carry the work: stress-test the model, scope and build product, design operations, unblock decisions.

Sparring

Regular conversations about whatever is hard right now. No template, no standing agenda. I push back when I think something is off. I also do some of this for free when the fit is right and the problem is interesting.

Operator sprints

I join for a defined period, usually two to six weeks, and take something off your plate properly. Build a thing, set up a process, unblock a decision that keeps slipping. Fixed scope, real output.

Fractional co-founder

For the right project at the right stage, I come in with a small equity stake and real operational involvement. I am selective about this and upfront about what I can and cannot commit to.

What I'm looking for

When it
fits

A few things make it a better fit.

  • You are building something in AI, automation, operations, or B2B tools.
  • You are early enough that a hands-on person still changes the trajectory.
  • You want someone who will be direct with you, including when the answer is that this is not the right move.

What I am not: a passive advisor who reviews the monthly update deck, or a generalist with no strong opinions.

Ventures

Building something?

The easiest start is a short note about what you are working on and where you are stuck. I reply to everything.
