Two presenters, one speaking into a microphone at a lectern with a laptop, on the AI Tech Stage at AI Week Frankfurt 2026, under blue-lit stage rigging and projectors in a glass atrium, with screens either side showing the application being presented and hackathon teams working at laptops in the foreground.

On the closing day of AI Week Frankfurt 2026, Kilian Leutner, Paul Patrick Klopsch and I joined the Codex Hackathon run by OpenAI and statworx. Condor Airlines set the challenge, claims management. In six hours the three of us built an agent for it with Codex and presented it on stage.

In research, an exploration that fails still teaches something. With six hours and a client's problem, every hour spent exploring was an hour not spent building, so we fixed the pipeline early, cut scope hard and decided fast.
