AI Reasoning: Found a confirmed investment: Araris Biotech, announced 04 Oct 2022. Calculating from that date to the reference date results in a time gap of more than 12 months but less than 36 months? Wait: From Oct 4, 2022 to Nov 1, 2025 is 3 years and ~28 days – that’s >12 months, so classification should be ‘low-active’. However check for more recent investments: search results show Tracxn entry dated Oct 19, 2025 mentioning Pureos Bioventures, but that is after reference date; irrelevant. No evidence of any investments within the last 12 months (Nov 2024-Nov 2025) or within last 6-12 months. The latest verifiable investment found is Oct 4, 2022 (Araris Biotech), which is more than 12 months ago. Therefore tag is low-active.

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.
