To accelerate AI adoption, Block intentionally dismantled its siloed General Manager (GM) structure, which had given autonomy to units like Cash App. They centralized into a functional organization to drive engineering excellence, unify policies, and create a strong foundation for a company-wide AI transformation.

The objective of an effective organizational flattening is to streamline the interactions and dependencies between teams, not just to remove people from an org chart. Companies that focus on redesigning workflows and communication patterns first, using frameworks like Team Topologies, achieve sustainable efficiency.

Rippling structures teams into business units led by GMs who oversee product, sales, and implementation. This is driven by the belief that a unified team focused on a specific customer problem (e.g., IT) delivers a superior end-to-end experience compared to a traditional matrixed organization.

To maintain the agility of acquired startups, Amplitude's CEO implemented a top-down ban on "decisions by committee." This empowers individual PMs to make decisions quickly without getting bogged down in universal alignment, protecting the fast-moving culture that made the startups valuable.

Lanzone structures Yahoo with autonomous business units ('states') led by general managers who own their P&L. Centralized functions like finance and HR operate at the 'federal' level. This balances entrepreneurial speed within units with centralized efficiency for shared services.

To maintain high velocity, Robinhood integrates legal and compliance partners into product development from the very beginning. By making them co-owners of the product vision, they become creative problem-solvers rather than end-stage blockers, which is crucial for shipping quickly in a regulated industry.

Block restructured from divisional GMs to a functional organization (Engineering, Product, Design) across all brands. This creates a single shared roadmap and forces alignment, enabling cross-unit collaboration that was difficult when incentives were siloed in separate P&Ls.

To avoid bureaucratic bloat, organize the company into small, self-sufficient "pods" of no more than 10 people. Each pod owns a specific problem and includes all necessary roles. Performance is judged solely on the pod's impact, mimicking an early-stage startup's focus.

To avoid bureaucratic slowdown, LEGO's CEO broke his leadership team into smaller, empowered subgroups like a "commercial triangle" (CCO, COO, CMO). These groups handle operational decisions, only escalating disagreements. This has cut full executive meetings to just one hour a month plus quarterly strategy sessions.
