AI Reasoning: Crunchbase shows Isaac Oates’ most recent personal investment was in Osium AI (Seed) with an announced date of Nov 22, 2023. Calculating from Nov 1, 2025, that investment was 23 months ago, which is more than 12 months – however, Crunchbase lists latest as Nov 22, 2023. Wait: Need to ensure correct tag mapping: less than 6 months => very-active; 6-12 months => active; >12 months => low-active. Since Nov 22, 2023 is 23 months before Nov 1, 2025, investor should be tagged low-active. However earlier data indicates other investments in 2022 and 2018. The most recent is Nov 22, 2023, so classification: low-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.
