What I do

AI for the energy transition

Our software measures every roof from satellite and aerial imagery – tilt, orientation, shading, usable area – and derives the optimal PV system together with its economics. In under a minute, for thousands of addresses at once.

Backing the next founders

As a board member of LAUNCH Rhein-Main e.V. I work on turning academic potential into real startups – through programmes like the Winter Batch and the Build Days, and a network of mentors, partners and investors.

Software & product

From geodata pipelines and machine learning to the product itself: what I enjoy is the whole path from raw imagery to something a sales team actually uses every day.

What I build

Kenergy Solutions

Automated photovoltaic planning. Our product Solar Insight turns any address into a finished PV offer with real figures in seconds – as a campaign across thousands of properties, as a single analysis in the Kenergy Hub, or as a plugin embedded on our customers’ own website. Founded in 2024 in Neu-Isenburg together with Jacob Bürkle and Max Schmidt.

How I got here

  1. 2023

    An idea for the roofs of Dreieich

    Right after school, one question: how do you actually find out whether a roof is suitable for photovoltaics? The answer became an AI that reads aerial imagery – and won the Audience Award as well as the „Environment & Sustainability“ prize at the final of the German national AI competition (BWKI) in Tübingen.

  2. 2024

    From project to company

    Kenergy Solutions GmbH is founded in Neu-Isenburg, alongside studying computer science. Stadtwerke Dreieich join as a strategic partner, using our analysis for the roofs of the entire city.

  3. 2025

    Scaling up

    More than 15,000 roofs analysed, further municipal utilities and sales partners – and a place in the LAUNCH Rhein-Main portfolio.

  4. Today

    Building and passing it on
