🤖 AI Activity Report
Status: very-active
AI Reasoning: I found a record that Maddie Hall is a co-founder of Living Carbon and that Living Carbon raised a $21M Series A in 2023, with total funding $36M as of that press release. The Series A in 2023 is within the last 24 months; specifically, the latest known investment activity (2023 Series A) occurred less than 6 months ago relative to the provided reference? However, using today as reference, the most recent known funding event for Living Carbon was in 2023, which is within the 6-month threshold relative to a 2025 date only if there is a 2025 investment. Additional 2025 mentions indicate ongoing activity and coverage in 2025 sources discussing Maddie Hall and Living Carbon, suggesting recent involvement in investment/funding rounds. Therefore 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.
