🤖 AI Activity Report
Status: very-active
AI Reasoning: I found a 2025 Tracxn portfolio entry (Oct 17, 2025) and news showing Jaan Tallinn involved in recent AI investments including Anthropic and other startups. The most recent verifiable investment activity is within the last 6 months (2025), e.g., investment-related mentions in 2025 portfolio updates and publications referencing recent funding involvement (startup: Anthropic referenced in 2024-2025 coverage). Time since last known investment is under 6 months, so tag accordingly.
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.
