🤖 AI Activity Report
Status: very-active
AI Reasoning: Crunchbase lists a funding event for Jamix with involvement by Zac Altman on Feb 21, 2024, which is less than 21 months ago. Wait calculate: From Feb 21, 2024 to Nov 1, 2025 is 1 year 8 months and 11 days – that’s 20+ months, which is more than 12 months. However also Seed Round – Alloy listed but date obfuscated; no evidence of investments within last 6 months. The last known investment (Jamix, Feb 21, 2024) is between 12 and 6 months? Actually it is more than 12 months. Therefore tag should be low-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.
