Status: active
AI Reasoning: Crunchbase lists Alvar Lumberg’s latest known investment as Supersimple (Pre-seed) announced Apr 2, 2024. From Nov 1, 2025 this is 20 months ago, which would indicate not-active; however Crunchbase also shows investments on Jan 26, 2024 (Esgrid) and Apr 2, 2024 is the most recent. Wait need recalc: Apr 2, 2024 to Nov 1, 2025 is 1 year 6 months 30 days ≈ 19 months >12 months. Therefore classification should be not-active.

Not Active – No known investments in the last 12 months.

Active – Known investments between the last 6 and 3 months.
