Every consulting firm faces the same question in 2026: How do we reorganize around AI? Three distinct architectures have emerged.
The Obelisk (Big Four)
AI replaces junior work. Small partner layer, massive AI base, 60-70% fewer juniors. Competes on efficiency and scale. Fatal flaw: talent pipeline crisis in 5-10 years.
The Hourglass (MBB)
Middle management is most automatable. Preserved partners and juniors, hollowed middle. Competes on judgment. Fatal flaw: missing rung problem.
The Box (Boutiques)
Kill the pyramid. Flat teams, 1:1 ratios, outcome pricing. Competes on expertise. Fatal flaw: cant staff large programs.
The Key Insight
The only losing move is not choosing — trying to preserve all options while competitors commit and execute.
