🤖 AI Activity Report
Status: active
AI Reasoning: Search results show Matt (Matthew) Keiser was CEO of LiveIntent and LiveIntent agreed to be acquired by Zeta Global with press coverage dated October 2024. I found no evidence of a personal investment by Matthew Keiser in 2025 or late 2024 (e.g., Sourcepoint or Fanbridge investments dated within the past year). However, LiveIntent’s acquisition and activity in Oct 2024 indicates involvement in transactions within the past 12 months but more than 3 months prior to the reference date. The most recent clear transaction linked to Keiser is October 2024 (LiveIntent/Zeta Global). That places his last known investment/transaction about 13 months before the reference date, but the acquisition is a company transaction rather than a personal investment. Given presence of activity around Oct 2024 and lack of any investment evidence after May-Oct 2024, the appropriate classification is “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.
