The Big 3 era of consulting hasn’t just slowed down; in 2026, it has hit a wall. Modern enterprises are no longer willing to fund massive overhead or wait months for a slide deck delivered by a junior team. Instead, the market has shifted toward strategic integrators, agencies that trade bloated boardrooms for elite talent networks and AI-first engineering.
