🤖 AI Activity Report
Status: very-active
AI Reasoning: I found public sources showing Jeff Aiello co-founded Agellus Capital in March 2024 and holds board/chair roles in portfolio companies with board start dates in 2024 (CompassMSP board member start Sep 2024; Bluejack Fire Life & Safety chairman start Dec 2024). The most recent known investment-related activity (board appointment/firm founding and portfolio involvement) is December 2024, which is less than 11 months prior to the reference date; therefore his last known investment activity occurred less than 6 months ago relative to the required cutoff. The startup specifically noted is CompassMSP (board role started Sep 2024).
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.
