48X vs Big 4 AI consulting: outcome in 48 hours, not strategy in 6 months
Big 4 AI engagements are partner-led, multi-month, and start with a strategy phase before any system ships. That model is built for large enterprises and large fees. 48X is built for serious SMBs. You want the Brain of your business or your codebase live this week, paid by the metric it moves. Not by hours and decks.
