In boardrooms and off-sites, AI is now the loudest conversation in consulting. But the tone isn’t always excitement. Behind closed doors, the big four firms are wrestling with something they’re not used to: a technology that doesn’t need their armies of analysts to be useful.
For decades, their model has been clear: throw high-calibre humans at a problem, capture the data, write the deck, hand it back. In this model, efficiency gains belong to the firm, not the client. AI turns that equation inside out.
The fear isn’t that AI will replace consultants tomorrow. It’s that it will make the client less dependent on the consultant today. If a local safety manager, a mid-level operations lead, or a project superintendent can get tailored, context-specific strategic thinking in minutes, what happens to the $500/hour retainer?
At ACN, we’ve gone the other way. We’ve built AI tools into the heart of our work — SPIRA for surfacing unspoken risks, Operating Without Harm for live leadership coaching, RiskSense for turning hazard data into live governance conversations. These aren’t side projects; they’re embedded in the same flow of work we run on site, in meetings, and with leadership teams. The tool is not the product. The product is the shift in the room when the right question lands at the right time — and AI can deliver that on demand.
What we’ve learned is that AI in consulting isn’t about replacing human insight — it’s about making it available to more people, more often, without the bottleneck of a formal engagement. Our clients can use a RiskSense prompt before a risk board, a SPIRA check-in before a high-pressure shift, or a Scaling Smart coaching dialogue before a growth decision. No “engagement letter” required.
The result? Leaders don’t wait for the consultant to come back with the answer. They have the conversation now, act now, learn now. And that’s exactly what the old model is afraid of — because once you’ve worked that way, there’s no going back to waiting weeks for a slide deck.
The real question isn’t whether AI will change consulting. It’s whether consulting firms are willing to change themselves. For us, the answer’s already clear: if our clients can do more without us, we’ve done our job.
