Hi
I'm Kai

I build ventures, products, and marketplaces.

Founder and (technical) product person based in Munich.

About me

I am a product engineer and builder at the intersection of technology, design, and business. I grew up in Stuttgart and got into software early because I was drawn to digital products, not just code.

That led me to study mobile media at HdM, where I learned how to combine software, design, and user experience into coherent products. More recently, I completed my studies in Management and Digital Technologies (MMT) at LMU in Munich.

Currently, I work as a Product Engineer at Knowunity, building AI-powered learning experiences. I enjoy working across product, design, and engineering, turning ideas into products that people love to use.

Alongside my work, I build and ship my own consumer products, including Zugkunft and Bon Ami.

Previously, I co-founded REICHARDT, a digital-infused fashion brand, and worked on digital products across startups and established companies. These experiences shaped how I approach building products today: connecting product thinking, design, and technical execution to turn ambitious ideas into reality.

Capabilities

Venture Building

I like working at the earliest stage, turning rough ideas into products, momentum, and clear direction.

  • 0 to 1 strategy
  • Partnerships
  • Founder-led execution

Product & Brand

I care about product taste, clarity, and how a company feels across every user-facing touchpoint.

  • Product sense
  • UX/UI design
  • Prototyping

Technical Leverage

I stay hands-on technically so ideas can be tested quickly and execution never gets blocked by translation.

  • Mobile and web shipping
  • AI-enabled tooling
  • Hands-on engineering

Zugkunft

Zugkunft keeps your long-distance train in sight on the Lock Screen, from leaving the house to arriving. Add a trip from DB Navigator, your calendar, or yourself, and stay ahead of delays, platform changes, and tight connections at a glance.

REICHARDT

At REICHARDT, I helped build a digital-infused fashion brand as co-founder and CTO. The venture pushed me to connect technology, brand, and product experience in a category where execution and differentiation had to work together.

FairPlanAI

FairPlanAI is an AI-powered trade fair intelligence product developed with Messe Munchen. It shows how I like to work on applied software: identify a real operational problem, turn it into a clear product, and use data and AI where they create practical leverage.

CollabNow

CollabNow was an early product launch focused on student collaboration. We built the app to make it easier for students to find collaborators, projects, and opportunities, which taught me a lot about community-driven products and adoption dynamics.
