🤖 AI Activity Report
Status: not-found
AI Reasoning: Search results and Joseph Loomis’s personal site show his roles (founder of CyberSponse, advisor roles) but do not provide clear, verifiable dates of any recent investments in 2023-2025 for startups like CyberSponse, Opus Security, Sleepyhead, or Island. I could not find documented investment transactions or funding dates within the last 12 months to classify his activity. Therefore 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.
