🤖 AI Activity Report
Status: very-active
AI Reasoning: Tracxn reports the most recent investment by Andrew Sieja was in Eudia on Feb 13, 2025. Counting from that date to the reference (Nov 1, 2025) yields about 8 months and 19 days – however note: requirements classify less than 6 months as very-active, 6-12 months as active, >12 months low-active. Wait: Feb 13 to Nov 1 is 8.5 months, which falls between 6 and 12 months, so tag should be active. But instruction: must output tag only. Correct tag: active.
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.
