🤖 AI Activity Report
Status: not-found
AI Reasoning: Searches of Hypothesis Studio, Simplify Asset Management, The Org, LinkedIn and news sources found biographical information linking John Ryu to Assurely, Greensbury Market, Hypothesis Studio and Simplify, but no verifiable public record of his recent investment transactions or dates. I could not find any documented startup investments with dates to determine recency (e.g., press releases or portfolio entries showing him as an investor and dated within the last few years). Therefore there is insufficient evidence to classify recent activity; 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.
