## Questions

### Who makes investment decisions at Mainfactor?

Co-founders Zak Tanjeloff (CEO) and Sam Hendel (President) lead investment decisions. Tanjeloff brought operational expertise from Live Nation, where he ran digital strategy for artist merchandise, while Hendel's background includes venture and operating roles. The firm has not publicly detailed an investment committee beyond the co-founders.

### Does Mainfactor operate as a private equity fund or a holding company?

Mainfactor functions as a permanent-capital holding company rather than a blind-pool fund. It acquires e-commerce and licensed-merchandise businesses outright and holds them indefinitely, reinvesting cash flows into operational improvements. This structure avoids the pressure to exit on a fund timeline, allowing multi-year replatforming and licensing-negotiation strategies.

### What is Mainfactor's relationship to Pharrell Williams and Billionaire Boys Club?

In February 2023, Mainfactor acquired full ownership of Billionaire Boys Club and its Icecream label from founders Pharrell Williams and Nigo (per Business of Fashion, February 2023). Williams and Nigo exited the operating business. Mainfactor now runs the brand's e-commerce, retail stores, and product development. The deal is the firm's highest-profile transaction to date.

### What is Mainfactor's known posture on co-investments alongside external partners?

Mainfactor has not publicly disclosed a co-investment program. The firm's deals appear to be fully self-funded acquisitions where it takes operational control. Allocators seeking co-investment rights should note the firm's holding-company structure, which does not align with the LP/GP co-investment model common in private equity.

### Which sectors does Mainfactor explicitly avoid?

Mainfactor avoids businesses without an organic cultural constituency. The firm targets e-commerce and merchandise operations where the customer base is built around fandom—music, fashion, or personality-driven brands. It does not pursue generic consumer-packaged-goods rollups or businesses where supply-chain margins cannot be materially improved by its operating playbook.
