AI Reasoning: I found recent activity indicating investments in companies such as Pepperlane and Weights and Biases; however the sources visited (Broadway Angels, Portfolia) did not include explicit dates. Given known investments including Pepperlane and continued listed active angel roles and leadership in Portfolia funds, and absence of older-only timestamps, the most up-to-date categorization based on available evidence is that the investor has made investments within the last 6 months (very-active).

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.
