🤖 AI Activity Report
Status: very-active
AI Reasoning: I found Nathaniel (Nat) Turner’s public investments list showing recent angel investments. The investments page lists active investments including Headway (invested) and many others; external sources such as Tracxn/PitchBook and his site show ongoing activity with portfolio additions as of 2025 (Tracxn entry Oct 17, 2025). The most recent identified investment activity is within the last 6 months (example: Headway listed among recent investments), so classify as very-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.
