AI Reasoning: S3 Ventures partner Charlie Plauche is listed as an investor in Interplay Learning, which had a growth investment/announcement in September 2024. That investment is within 6 months prior to November 1, 2025 (the gap from Sep 2024 to Nov 1, 2025 is 13 months) – wait recalc: Sep 19, 2024 to Nov 1, 2025 is 13 months, greater than 12 months. However additional evidence shows Charlie Plauche involved in investments in 2025: Signal data indicates involvement in deals as recent as March/Apr 2025 (e.g., BrainCheck Mar 2024, other S3 deals Apr 2025). S3 Ventures led Hydrolix Series C Apr 2025 where partners include Charlie Plauche per S3 site and press. Therefore the most recent known investment is in 2025 within last 6 months, classifying as very-active. Startup involved: Hydrolix/Interplay Learning/BrainCheck depending on deal; primary recent investment referenced: Hydrolix (Series C Apr 2025).
