🤖 AI Activity Report
Status: not-found
AI Reasoning: Searches found profiles and historical roles (ProgrammableWeb, API Science) but no clear, verifiable recent investment activity with dates from reliable sources. Crunchbase listing suggests past investments like TeachStreet (older) but date was obfuscated in the scraped result; no confirmed investment date within the past several years was found. Because I could not verify a recent investment date to place within the 6-12 month windows, defaulting to not-found.
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.
