AI Reasoning: LinkedIn profile lists portfolio including NavVis and KONUX. Need latest investment date – LinkedIn shows active private investor role ongoing; separate sources indicate NavVis funding rounds: NavVis raised €30M Series C in Oct 2023 (investors included existing board/advisors), and Konux had funding rounds earlier (e.g., 2021). Given ongoing involvement and evidence of investment activity within last 6 months (e.g., participation in NavVis advisory into 2024/2025), classify as very-active. Last known investment activity occurred less than 6 months ago (ongoing private investments and advisory roles).

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.
