🤖 AI Activity Report
Status: low-active
AI Reasoning: Searches show Sigma Prime Ventures’ recent investments for which John Simon is a managing director include portfolio activity with last recorded investments in 2023 and earlier; Tracxn and VentureFizz indicate no Sigma Prime investments in 2025 and the most recent listed portfolio activity dates are 2023 and 2022. The startup ‘Interactions’ shows acquisition activity in Sep 10, 2025 but the firm’s last direct investment entries are older than 12 months. Based on the absence of any investment by John Simon within the past 12 months, classify as low-active.
Angel activity thresholds:
Low Activity – Only known angel investments more than 12 months ago.
