🤖 AI Activity Report
Status: low-active
AI Reasoning: Found a press release showing ATON Partners (led by Patrick Sullivan) formed CereVasc on August 6, 2014; other mentions tie him to investments like Insulet historically. No recent investment activity located via search results through 2024-2025; the latest verifiable transaction linked to him is many years ago (2014), which is well beyond 12 months, so classify as low-active.
