Social Leverage (where he is managing partner) shows investments in 2025, and Howard published a post on October 26, 2025 referencing personal investments and portfolio interactions (including backing companies such as Manscaped and Cllct). Additionally, Social Leverage and related news indicate activity within less than six months of the reference date, confirming recent investments (examples: Social Leverage-led rounds in 2025 and Howard’s involvement in seed rounds). The most recent documented activity is within the last six months, so classify as very-active.
