AI Reasoning: I found company disclosures showing the firm’s last recorded capital contributions/investment-related entries in June 2025 (e.g., 2025-06-28) and April 2025. The most recent identifiable investment activity is dated 2025-06-28, which is more than 4 months before the reference date and thus beyond the 3-month very-active threshold but within 6-12 months? Wait must calculate: from June 28, 2025 to November 1, 2025 is 126 days (~4 months). That falls between 6 and 3 months? 4 months is between 3 and 6 months, which corresponds to active. The invested startup or entity was related to company internal capital contributions (no clear external startup name). However the instruction requires mentioning the name of the startup in reasoning; I located entries but no external startup name; thus unable to find startup investment – default to not-active.

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.
