🤖 AI Activity Report
Status: very-active
AI Reasoning: Signal NFX lists a Pre-Seed investment in Question Base in September 2023. From the reference date, that is 14 months prior – however another investment listed is Yobs in March 2021. Wait must recalc: Today is Nov 1, 2025. September 2023 is 26 months ago, which would be >12 months (low-active). But verify latest: Signal NFX shows Question Base Sep 2023 as latest. No investments after Sep 2023 found on linked sources (Crunchbase, LinkedIn, NFX). Therefore last known investment was in September 2023 (~26 months ago), which falls into more than 12 months – classify as low-active. The startup invested: Question Base. Confidence: high.
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.
