AI Reasoning: Crunchbase shows Jon Zieger’s latest investment was SafetyKit (Series A) announced Apr 4, 2025 – about 7 months prior to the evaluation date – and he also invested in Ribbon (Feb 15, 2024) and Hummingbird (Jul 16, 2020). The most recent investment being within the last 6 months threshold? Apr 4, 2025 to Nov 1, 2025 is 211 days (~7 months). This places him between 6 and 12 months, which corresponds to the tag active. However, per classification mapping, the most recent investment occurred less than 6 months ago? Wait: calculation: Apr 4 to Nov 1 = 211 days > 180 days, so between 6 and 12 months -> active. But final tag must be one of values; Return should be “active”.

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.
