🤖 AI Activity Report
Status: low-active
AI Reasoning: I found evidence that Jeffrey Leventhal (S12F) participated in Shiftsmart’s $95M Series B announced December 2, 2021. That investment is older than 12 months (approximately 47 months before the reference date), and I found no more recent investments attributed to him or S12F after that date in the sources searched. The startup mentioned: Shiftsmart.
