🤖 AI Activity Report
Status: very-active
AI Reasoning: I found a Feb 13, 2025 investment where CapitalT (quotes from Janneke Niessen) led a round in AI-BOB. From Nov 1, 2025, that investment is 8 months and 19 days ago – wait recalc: Feb 13 to Nov 1 is 8 months and 19 days, which is between 6 and 12 months -> tag should be ‘active’. However instructions require output only the tag. Returning tag now.
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.
