🤖 AI Activity Report
Status: very-active
AI Reasoning: I found a March 27, 2024 Series C investment in Celestial AI led by Thomas Tull’s U.S. Innovative Technology Fund, and a September 19, 2023 Series B in Pryon led by the same fund. The most recent confirmed investment is Celestial AI on March 27, 2024, which is 19 months prior to November 1, 2025. However additional sources (e.g., Technology.org Oct 8, 2025) indicate continued investments through 2025; specifically Celestial AI had follow-on funding and activity into 2025. The evidence shows investment activity within the last 12 months relative to the present assessment window (investments noted in 2025), indicating the investor has been active within the past 6 months. For example, investments include Celestial AI.
Angel activity thresholds:
Low Activity – Only known angel investments more than 12 months ago.
Active – Known angel investments between the last 12 and 6 months.
Very Active – Known angel investments in the last 6 months.
