## Questions

### Who runs investment decisions at Fernbrook Capital Management?

Managing Partners William F. Detwiler and Marigay McKee jointly lead investment decisions. McKee's operating background as Chief Merchant at Harrods provides a sourcing and evaluation filter rooted in brand-revenue reality. Shreyans Dugad serves as Investment Team Principal, supporting deal execution.

### What investment stages does Fernbrook Capital Management target?

The firm invests across early-stage, seed, startup, and growth equity rounds, concentrating on revenue-stage companies. This spans from initial commercial traction through established scaling phases. The unifying criterion is demonstrated revenue in software, marketplace, or eCommerce verticals.

### How does Fernbrook source proprietary deal flow?

Fernbrook's deal flow derives substantially from the personal networks of its managing partners and its strategic advisor roster — former senior executives at Gap Inc., Amazon, Blackstone, and Bain & Company. McKee's fashion and luxury retail network provides early visibility into digitally native brand ecosystems.

### How is Fernbrook's strategic advisor model structured?

Strategic advisors include active industry executives such as Vanessa von Bismarck (BPCM) and former operators from Gap and Amazon. They are not full-time Fernbrook employees but provide deal-sourcing, diligence, and post-investment guidance. This embeds current-practitioner expertise into the investment process.
