🤖 AI Activity Report

Status: active

AI Reasoning: Greentown Labs runs climate-tech accelerators and published activity in 2024 including cohorts and investments (e.g., Ardent, Maple Materials, Oxylus Energy, Phlair, Aquasaic, Cellsense, EcoForge) with documented cohort activity in 2024. The most recent confirmed investment/cohort involvement is in 2024; assuming today is Nov 1, 2025, the last known investment occurred between 12 and 6 months ago (in 2024 within the last year but more than 6 months ago), placing them in the ‘active’ category.

Here are the thresholds established for the different statuses:
Not Active – No known investments in the last 12 months.
Low Activity – Only known investments between the last 12 and 6 months.
Active – Known investments between the last 6 and 3 months.
Very Active – Known investments in the last 3 months.
