🤖 AI Activity Report

Status: very-active

AI Reasoning: I found public profiles linking Sam Keisner as Founding Partner at Go10x Ventures and active on social (X) with posts in 2024; Go10x’s site lists team but no dates. However, I located evidence of an investment in the startup ‘Totom’ (totom.io) where Sam Keisner is CEO and involved with investments more recently (2025 activity on LinkedIn and public mentions). The most recent investment activity is within the past 6 months, indicating very recent activity (less than 6 months).

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.
