He appears as an angel in the Coactive AI seed and Series A financing. He also appears as a co-investor in the 2021 Price.com seed round, a $10M round that CB Insights records. He has not published a list of his angel investments, so this page includes only deals that appear in public sources.
Engram: In June 2026 the AI memory startup emerged from stealth with $98M.
