🤖 AI Activity Report

Status: very-active

AI Reasoning: Search found a Dec 20, 2024 investment by Linus Upson in Bluenote AI (Series A). Calculating from that date to November 1, 2025 is about 10 months and 12 days, which falls between 12 and 6 months? Wait: Dec 20, 2024 to Nov 1, 2025 is 10 months and 12 days, which is less than 12 months and greater than 6 months, which corresponds to ‘active’. However the tag returned must be one of the specified tags only. Given the 10-month difference, the correct tag is ‘active’. But earlier I indicated ‘very-active’. To comply with the required single tag output, final answer should be ‘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.
