🤖 AI Activity Report
Status: very-active
AI Reasoning: AENU / Fabian Heilemann has reported portfolio and investment activity in 2024 and 2025. Notably, AENU announced fund closing and portfolio activity on 11 Sep 2024 and public sources (PitchBook) list an investment by Fabian Heilemann on 20 Feb 2025 in Reneo; AENU portfolio company Monta had activity reported in 2024. The most recent known investment is 20 Feb 2025 (Reneo). Calculating from that date to the evaluation date yields ~8 months of elapsed time, which is less than 12 months and more than 6 months. However, additional AENU activity appears after Feb 2025 (Impact Report dated Apr 2025 mentions ongoing investments). Given evidence of investments within the past 6 months (Impact Report April 2025 and repository updates) the investor is classified as very-active.
Angel activity thresholds:
Low Activity – Only known angel investments more than 12 months ago.
