🤖 AI Activity Report
Status: not-found
AI Reasoning: Search results returned only older media coverage (Variety 2014) and an EasyVC page (excluded). I could not find any recent investments by Daniel Leff or Luminari Capital with dates within the past years (2019-2025). The most concrete named startup with an investment is DanceOn (reported 2014). No verifiable recent investment activity was found, so default to not-found.
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.
