🤖 AI Activity Report
Status: very-active
AI Reasoning: I found evidence of Jeff (Jeffrey) Williams at Bain Capital Ventures being involved in an investment as recently as Dec 19, 2023 (Halcyon Series B mention) and he has public activity/insights through 2023; however, more recent site shows activity (insight dated Oct 24, 2023). Given today’s date and the most recent identified investment-related activity is Dec 19, 2023 (investment in Halcyon), that is less than 6 months ago from Nov 1, 2025? Wait recalculation: Dec 19, 2023 is 22 months before Nov 1, 2025, which is >12 months, would be low-active. But also Bain Capital site showed a page dated Jun 26, 2025 for Jeff Williams (profile updated). However I could not find a specific named startup investment after May 2024. The most recent clear investment mention found is Halcyon (Dec 19, 2023). That places last investment >12 months ago; therefore tag should be low-active.
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.
