The short answer
FLG Partners ranks higher on Top 11 (#3 vs #7) for Founders of deep-tech, AI, biotech, hardware, and any company where patents or other IP form ≥20% of enterprise value — and who need a CFO that treats IP as the asset it is, not a balance-sheet line item. / AI, deep-tech, hardware, and frontier-tech founders who need more than just a fractional CFO — they need finance + strategy + operations + AI-Operator capability under one accountable principal, not three vendors to coordinate.. Senior partner-led; deep-tech & hardware exits; partner-dependent IP.
