🤖 AI Activity Report
Status: active
AI Reasoning: Found evidence Signe Ostby participated in ThinkCERCA’s Series B (article dated Sep 20, 2017) and was an investor in LightSail’s Series B (articles dated Mar 2016). No more recent investments found in searches. The most recent known investment activity is ThinkCERCA in Sep 2017 – which is over 12 months ago but less than many years; specifically from Sep 20, 2017 to Nov 1, 2025 is 8 years and ~1.5 months. That places last investment well beyond 12 months; however the instruction mapping: last known investment >12 months = low-active. But considering there is mention of LightSail in Mar 2016 earlier than 2017, the latest is 2017. Therefore classify as low-active.
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.
