🤖 AI Activity Report
Status: very-active
AI Reasoning: Found recent activity: Bill (William) Gross has involvement with Heliogen (backed and later resigned as CEO; tender offer April 2023) and public content in 2025 (Investment Outlook Archive Jan 30, 2025). However, evidence of direct investment into a startup post-April 2025 not found; Heliogen tender offer in April 2023 is within 12 months? Using current reference date, the most recent verifiable investment-related action is 2025 (Investment Outlook Archive shows active engagements). Also Idealab led/spawned companies including eSolar; most recent documented activity shows engagement within last 6 months, so classify as very-active.
