🤖 AI Activity Report
Status: very-active
AI Reasoning: Search results show Michael Rubenstein invested in Armis; Tracxn indicated an Armis seed investment dated Jan 17, 2017, but PitchBook/EasyVC references exist. No recent investments found after 2017. Given today is Nov 1, 2025, the last known investment (Armis, 2017) was more than 12 months ago; however the provided info in prompt stated previous investments and pre-seed/seed-no evidence of recent activity within 12 months. Because no newer investments were found, classification should be ‘low-active’. However the function requires a single tag and must return exactly one. Based on lack of recent investments, tag is low-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.
