Only 9% of Senior Consulting Alumni Still Work at a Big Firm. Clients Have Noticed.

Only 9% of senior consulting alumni in one large network still work at a major consulting firm. Across all levels of seniority, the figure is 23%.

Those numbers come from a white paper Movemeon published in October, drawn from its network of more than 100,000 strategy and transformation professionals. It's worth saying up front that Movemeon runs a business placing independent consultants, so it has an interest in this story. But the direction of the finding is hard to argue with, and it's a pattern many senior independents will recognize: the more experience people have, the more likely they are to have left.

The paper's other numbers describe who's buying them. Forty-nine percent of the independent consulting projects Movemeon delivered over the past two years came from private equity firms or PE-backed companies. A quarter of the mandates clients approached it about in the second quarter of this year mentioned AI, against roughly one in six a year earlier.

If you run a boutique advisory firm, this is your competitive landscape changing in real time, and it cuts both ways.

Clients are buying senior judgment directly

For a long time, the way a company got senior advisory judgment was to hire a firm and accept the model that came with it: a partner who sells, a team that delivers, and a bill that pays for both. The Movemeon data suggests a growing share of clients are skipping that structure and hiring the senior person directly, in small teams, for specific work.

Private equity is the clearest example, and it makes sense that it would lead. PE firms tend to buy outcomes on a clock, know exactly what they need done in a portfolio company, and have little patience for paying for a pyramid. When half of a talent marketplace's projects come from PE, that's a buyer telling you how it prefers to purchase expertise.

For a boutique advisor, this is mostly good news. The thing you've always sold, senior judgment without the bench, is now what a lot of clients are actively looking for. But it also means you're competing with a much larger pool of senior people who left the big firms and are selling the same thing.

Clients say analysis is easy to get

The Movemeon paper makes one claim that every advisor who sells analysis should sit with. "Analysis has never been easier to get," it says. Between in-house strategy teams, former consultants now working inside the business, and AI tools, "most organisations already know what they need to change. What they lack is the capacity and experience to make that change happen."

That's a marketplace selling delivery talent, so it would say that. But the AI numbers point the same way. When a quarter of mandates mention AI, Movemeon's read is that "clients want people who can put AI to work in the business, not just a strategy for it."

For a boutique that sells judgment, this is a useful warning about where the value is moving. If the client can get a competent analysis from its own team and a model, the advisor's job isn't to produce more analysis. It's to tell the client which parts of it matter, what they're missing, and what they'd be wrong to do, and to put a name to that judgment.

Pricing is moving off the hour

The second shift is in how the work gets priced. In an interview with Mint in late October, Eisner Advisory Group's CEO said billing is "moving from rates and hours to subscription-based services, bundled services, output pricing and value-based pricing," and predicted that over the next six to eighteen months it would "drive a radical evolution of professional services." That's a prediction, not a measurement, but it comes from someone running a large firm and deciding where to invest.

Brynjolfsson and Petropoulos made the economic case for the same shift in a paper from Stanford's Digital Economy Lab this summer. When AI does a growing share of the work in ways the client can't see, "time-based pricing becomes a worse instrument than it was, because hours are no longer reliable proxies for effort." A client can't tell whether the twelve hours on the invoice were twelve hours of thinking or two hours of thinking and ten of a model's work, so the hour stops being a useful thing to buy.

Put those two shifts together and you get the market a boutique advisor is now selling into. Clients can hire senior people directly, and they're less and less willing to pay for that judgment by the hour.

What a boutique has that a marketplace doesn't

When senior talent is easy to find, being senior stops being a differentiator on its own. Every independent who left a big firm can say they've done the work for a decade. What a boutique can offer that a marketplace placement usually can't is a way of working the client can see and rely on.

That looks like a few specific things. A consistent method, so the client knows what they'll get before the engagement starts. Work products the client keeps and can use after you've gone, rather than a deck that only makes sense with you in the room. Findings the client can check for themselves, with the evidence attached. And a price attached to the question being answered, not to the hours it took.

None of that is new advice, but the Movemeon numbers and Eisner's prediction make it more urgent. A client choosing between a boutique and a senior independent from a marketplace is mostly choosing between two senior people. The one who can show how they work, and what the client gets at the end, has an easier sale.

What to change in how you sell

If you're a boutique advisor or a senior independent, a few changes follow from this.

Stop leading with where you used to work. When most senior people have left the big firms, a big-firm pedigree gets you into the conversation and does very little after that. Lead with the question you answer and how you answer it.

Price the answer, not the hours. If clients are moving away from paying for time, a proposal built from days times a rate is pricing yourself into the category that's shrinking. I wrote about what hourly billing does when AI speeds up your work, and the same logic applies here.

Make the method visible. A short description of how an engagement runs, what the client receives at each stage, and what they keep afterward does more to separate you from a marketplace placement than another case study.

Know where your hours actually go. The economics of a small practice depend on how much of your time goes to work only you can do. That's the difference I described in what a one-person advisory firm's margin looks like, and it matters more when clients are comparing you to someone who can start next week.

The senior people have left the big firms, and the clients have followed them. The advisors who do well from here will be the ones who make it obvious, before the first call, what a client gets that a résumé alone can't promise.
