The thesis
Why this org is unusual
Four ecosystem-oriented leaders—Ecosystem, Business, Engineering, Finance/People, and Legal—report directly to the CEO.
This emphasizes Block’s divisional model, where Square, Cash App, Bitcoin, and TIDAL operate with substantial autonomy.

The structure reflects Block’s strategy of running distinct platforms with shared infrastructure rather than a purely functional hierarchy.
- CFO also serves as COO and People Lead
- Distinct ecosystem P&L ownership
