AI Reasoning: I found a Mitsui & Co. press release showing an investment in NumberAI (Numa) dated Oct. 2, 2024. The date difference between that investment and the reference date is between 6 and 3 months (approximately 13 months? Wait recalc). Oct 2, 2024 to Nov 1, 2025 is 13 months – that’s more than 12 months, which would be ‘not-active’. However, other Mitsui pages show investments in Dec 19, 2023 (E12 Ventures) and multiple 2025 announcements of investments in May 2025 (e.g., May 9, 2025: additional investment in aircraft engine-related business). The May 9, 2025 announcement indicates an investment within 6 months of the reference date (less than 6 months but more than 3 months), placing the last known investment around May 9, 2025. That date to the reference date is almost 6 months, slightly less than 6 months? From May 9 to Nov 1 is about 5 months and 23 days, which falls between 6 and 3 months? It’s just under 6 months so falls into ‘active’. Therefore tag as 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.
