🤖 AI Activity Report
Status: not-found
AI Reasoning: Searches found historical mentions of Dr. Rolf Käse as an angel investor (notably involvement with Transcatheter Technologies and recognition in 2015), but I found no verifiable record of any investment or financing activity within the last several years up through November 1, 2025. The most concrete referenced investment events and public mentions date back many years (e.g., 2013 and earlier). Given absence of recent investment dates, defaulting to not-found as no recent investment information could be confirmed.
Angel activity thresholds:
Low Activity – Only known angel investments more than 12 months ago.
Active – Known angel investments between the last 12 and 6 months.
Very Active – Known angel investments in the last 6 months.
