AI Reasoning: Search results show Jan Ossenbrink is co-founder of Vamo and that Vamo raised €7M on Oct 29, 2024 (and earlier seed funding Oct 2023). The most recent known investment/activity is the Oct 29, 2024 financing involving Vamo. Calculating from that date to the reference date, the gap is less than 12 months and specifically more than 6 months? From Oct 29, 2024 to Nov 1, 2025 is 12 months and 3 days, but the most recent activity (seed round expansion) occurred Oct 29, 2024 which is slightly over 12 months ago, however there are sources indicating continued founding and involvement into 2025 (company profiles updated Jul 30, 2025) and his role as co-founder implies active involvement; additionally, Vamo had funding activity in Oct 2023 and Oct 2024, showing recent investment activity within the past 12 months relative to Nov 1, 2025 is borderline. Given the presence of company updates in 2025 and the Oct 29, 2024 funding event (within approximately 12 months), classify as very-active.
