🤖 AI Activity Report

Status: very-active

AI Reasoning: Third Rock Ventures has multiple portfolio/press updates in 2025 including ARTBIO (Series B announced July 29, 2025) and Tango Therapeutics (multiple 2025 entries, e.g., June 27, 2025). The most recent investment-related company announcement is from July and later portfolio news through October 2025 show activity; the most recent direct investment/financing announcement found is ARTBIO Series B on July 29, 2025, which is within 3 months of the calculation date (less than 3 months). Therefore classify as very-active.

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.
