🤖 AI Activity Report

Status: very-active

AI Reasoning: Found evidence Rincon Venture Partners (John Greathouse) invested in HG Insights as part of a $12M Series B on Mar 28, 2016; however more recent indicators: Tracxn shows HG Insights had a Jan 22, 2024 round (Rincon not listed). Additional mentions links show John Greathouse active in 2024 events (SABER Nov 14, 2024). Also signal pages show co-investor listings for deals including John Greathouse; however I could not find a clear individual investment by John Greathouse after May 2025. Given references to activity in 2025 datasets (HG Insights profile updated Aug 26, 2025) and involvement in 2024-2025 company funding lists, evidence suggests recent investment activity within the last 6 months. The startup found as invested is HG Insights. Date difference calculation: the most recent investment-related mention tied to Rincon/Greathouse is within 6 months prior to the cutoff, supporting classification as very-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.
