# Alternative Firm Geometries: Diamond, Network, Platform

The primary source argues consulting is moving from pyramid to **obelisk** ([[concept-consulting-obelisk]]). Independent commentary broadly agrees the junior-heavy base is shrinking but disputes which single shape wins. A downstream agent should treat the obelisk as **one of several plausible geometries**, not a foregone conclusion. This note (enrichment-derived) catalogs the alternatives.

- **Diamond** — Boutique Consulting Club's "The Consulting Pyramid Won't Die. It'll Change Shape" proposes a diamond: a thin base of tool-literate AI facilitators, a **thick middle of domain experts/architects**, and a compact partner apex. Argued as "the most credible" future because a stronger mid-tier preserves apprenticeship and judgment. "A tight 10-person diamond can out-margin a 20-person pyramid."
- **Network / Hybrid** — Methus: "The future firm is not a pyramid… it is a network of human and machine intelligence… hybrid organisational models — flatter, modular, integrated teams." Strat-Bridge: a "flatter network of high-judgment consultants supported by AI infrastructure."
- **Platform** — Future-of-consulting pieces describe "from pyramid to platform": firms build proprietary AI platforms, knowledge graphs, and data assets and **sell outcomes/subscriptions, not hours.** Emphasizes platform leverage over team geometry.

**Leverage redefined:** Strat-Bridge's synthesis — "AI is not removing leverage. It is redefining it" — captures the shared thread: leverage shifts from human hierarchy to AI infrastructure. This directly complicates [[claim-pyramid-collapse]]'s "collapse" language and grounds [[contrarian-structural-change]].
