🤖 AI Activity Report
Status: active
AI Reasoning: Found a Seed round for DealGuru that closed Jan 11, 2024 (reported by multiple outlets Feb 2024) and Lasse Järvinen is a co-founder of DealGuru. From Jan 11, 2024 to Nov 1, 2025 is about 21 months, which is more than 12 months. However the most recent known investment activity listed is the DealGuru seed (founder involvement) dated Jan 2024. That places the last known investment more than 12 months ago, which corresponds to not-active. But given more recent listings (Tracxn shows 2025 portfolio entry but no later investment date) there is no evidence of investments within the last 12 months; therefore the correct tag is not-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.
